.NET Application Architecture


ClickOnce will now detect if the ClickOnce application store has become corrupted. In the event of store corruption, ClickOnce will automatically attempt to clean-up and re-install broken applications for users. Developers or admins do not need to do anything to enable this new behavior. This makes machines easier to manage. You opt into this behavior by targeting. Please tell us if you would like that behavior.

This change significantly improves connection reliability. An ExportParameters bool method was also added for exporting the key using explicit curve parameters. Create ECCurve factory methods. This functionality is provided by system libraries, and so some of the new features will only work on Windows You can see an example of.

You can start building. You need to select the. The following Windows versions will be supported same as. NET targeting packs page. The improvements in the. NET Framework take advantage of new Windows 10 client features and make general improvements for all Windows versions. Please do tell us what you think of these improvements.

Save my name, email, and website in this browser for the next time I comment. Not quite sure why the release notes seem to talk about TLS 1.

Personally, I think having those enabled by default would make far more sense, given how often it is being recommended to switch completely to TLS 1. This particular change tracks the fix for Message Security. The fix was quirked in. Hence you would need to intentionally retarget your application to. So, there is no answer for this question? I just found it https: An answer was provided over here: NET Standard and the changes to. I can say even though I exclusively use.

NET proper is suffering as a result of the need to coordinate from all these separate frameworks. Is there a plan yet for doing this? When will it be communicated publicly? NET at any given point in time thus my prior two questions. NET is supposed to be open-source now, is there a way to improve this communication with the community? Perhaps design notes and roadmaps like the language teams are doing?

There are millions of apps that are running on. NET Framework and they will continue to be 5 and 10 years from now. NET Framework is like a star with many planets and comets and asteroids that orbit it due the gravity that it exerts on them.

So, you can choose to see that as a bifurcated effort and costing us focus on the team. In reality, we work hard to leverage our efforts across. NET Core and increasingly Xamarin, too. When we build a feature, it costs us 1. Make it once, sell it 3x customers. Communication could be a lot better. There are not many announcements there yet, but there will be. We also have a design repo planned, too. NET Core and Xamarin to become the same thing. My understanding is with.

So make all that stuff platform specific,. NET Core compatible and move towards one version. I find it hard to believe the long term plan is really to maintain 3 different frameworks. NET Core and not. Differences like this in tooling and functionality will only grow over time.

Will there be some pain merging the frameworks? Apple breaks backwards compat worse than this and gets away with it. You can even make upgrade tools to assist like Apple does. Merging the frameworks would be super expensive and likely result in unhappiness. Instead, we intend to continue to add value to all the.

NET products and make it increasingly easier to move code between them. NET Standard and a uniform project format come in. There is a reason why Microsoft has become pretty successful with large corporate and government customers … because we work harder than almost any other company to keep apps working over long periods of time. I say almost since IBM has a long history of similar, actually even more herculean, efforts.

They do want new and innovative features from us, but they expect all their existing code to work at the same time. We do intend to make. It will come in later releases. NET Core and enable it for other project types in the same release, particularly with our short releases.

It is not enough to list a bunch new parameters options and API names without a mapping between old and new. If the metric 1. It is very handy that 4. Is it then fair to say that there are also no plans to merge Mono either? Right … No plans to merge Mono. We believe that this approach is the best choice. I updated the release notes with a link to the coreclr repo. Could you share some more details regarding Azure connections reliability?

What protocol was used before? Ah, you are welcome! Seeing that ValueTuple was now in. I happened to spot a typo in… https: We are very close to enabling the full open source experience for the.

I expect it will take another week. Anyone knows where this is located in the documentation? Check out this page. It is clearer on this point: This will delay adoption of better high DPI support for years.

I hope this will be fixed in future updates, having a dependency on everything being compiled against. It is only available for WinCU right now. It is supposed to be available for others later I guess soon. At least that is how I read it. That helps a bit, still having to compile every component against. If its just for the manifest then I could recompile my.

We totally understand the desire to make these improvements available on Win7 however the underlying operating system does not support the features WinForms needs in order to make per-monitor DPI support Dynamic DPI available. Additional control behavior improvements may also require underlying Windows OS feature as in improvements to comctl If our app is built against 4. If your app is targeting an earlier version than 4.

There is a check done at startup that checks: So to summarize the new information, it looks like once. It is stated in the post that not only the application should be compiled against. Will this manifest prevent this application from running on earlier Windows versions? Declaring Windows 10 support in the manifest will not prevent the application from running on other OSes. You can read a bit more at: I would guess that the answer is no. Install fails, and yet there is still no proper way to report errors other than through Visual Studio itself which still does not work for me.

It fails to install the. Net Core SDK 1. Yet it is not. You see loads of people have the problem: I logged a bug on git: While you are reading. Whenever I sign in I get the error: We are doing our best to fix the problem as soon as possible.

Name made it into this release. Also, kudos on naming this 4. The minor point releases were really annoying as it makes it harder to remember and discuss with IT what version we need to be on. It will be available on the same Windows versions at 4.

I updated the blog post to make this clearer. I have a request just like everyone else on this page apparently! Can you guys take ownership of the Chocolatey packages for the framework and targets and keep them updated?

Can you point to the ones you are referencing? The Magnifier tool is actually pretty useless for testing high DPI, because it just does a bitmap scale up.

I updated the text on Magnifier. I believe it is correct now. I am able to select build Anyone had a similar experience? So it seems that. So, apparently you need to enable it manually. That did the trick for me.

Yes, you have to make this choice in setup see the image in the post. New WPF Touch support: Do I have to target Framework 4. From the MSDN entry: Can you double check? Has any of this made its way back to. NET desktop framework is just not getting the same love and attention as. Yes, a bunch of. The team is sharing them with me.

I already added a link for the GC change, to. Are there benchmarks or numbers for perf increase when you move an mvc 5. NET Framework release includes performance-related improvements. You said that 4. More than 3, less than 10 and hopefully closer to the first number. We have some quality-related process to still go through to get the release ready. We now have to get the product ready to ship for nearly over a dozen different variations.

For those of us not using Win 10, what are some of those improvements that are not W10 -specific? Very few other things were Windows 10 specific. I have Creators Update and latest VS version Sadly, PropertyGrid uses the same color not just for grid lines, but also for the left border and category names background.

As a result, all property grids using default colors now look… well, rather ugly. We made the change in order to comply with industry standards http: We appreciate your feedback around your scenarios and will consider making changes in a future release. The PropertyGrid control looks super dark and ugly now in a normal non-High Contrast mode. Please give us some way to revert this behavior without requiring us to recompile and target.

If you explicitly set the LineColor property to SystemColors. InactiveBorder at run-time, then the control will respect that and use the InactiveBorder color like it used to. This was an easy change for me, but I already hate looking at the PropertyGrid in other. Some examples for options pages that are super dark now are: The team is taking another look at this one. We have asked both Microsoft accessibility and designer folks to help us make a better choice. This was a bad choice of words, going back to earlier phrasing.

The main point is that UWP has touch as a first-class experience from its initial design. Clearly, for UWP, keyboard and mouse have to first-class, too. I am not sure if I have this problem earlier in my life. My advice would be to contact the vendor for support. Unfortunately, we are currently experiencing an issue with spell checking which has occured after update to. The new touch setting Switch.

Please make a possibility to choose English language in Visual Studio Installer. For example, I spent 30 minutes trying to figure out how to switch on. Is there a link to more information about the ClickOnce updates? For the Store Corruption Recovery, does the application installed via ClickOnce have to target the 4.

Or, does the ClickOnce deployed app just need to be running on a machine with the new framework installed? The application does not need to target. You are correct —. Hi, we are a group of student and we have a project that we need to develop a new small language.

We can target any run time. But , all students in our group have. There is only one book out there and it is very old. You might like to look at the Dynamic Language Runtime which is a set of APIs that enable you to implement dynamic languages.

Often DSLs are more dynamic in nature vs. These are the same expression trees used by the C compiler when you create LINQ queries, but they have been expanded to support control flow and more than just expressions. All the code that implements the Sympl example language in C or IronPython is here: Building a proper parser generator is very difficult unless you use tools like the above.

Good to know that. Net Core, any updates on the future of WCF supporting the rest hateoas in built to this framework space? I installed Windows 10 Creators Update and. But it seems that all my existing ASP. An unhandled exception occurred during the execution of the current web request. On 31 March , Microsoft announced at Microsoft Build that they will completely relicense Mono under an MIT License even in scenarios where formerly a commercial license was needed.

These developments followed the acquisition of Xamarin , which began in February and was finished on 18 March Microsoft's press release highlights that the cross-platform commitment now allows for a fully open-source, modern server-side. Common Language Infrastructure CLI provides a language-neutral platform for application development and execution. By implementing the core aspects of. NET Framework within the scope of CLI, these functions will not be tied to one language but will be available across the many languages supported by the framework.

It serves as the execution engine of. NET Framework and offers many services such as memory management , type safety , exception handling , garbage collection , security and thread management. All programs written for. Each assembly consists of one or more files, one of which must contain a manifest bearing the metadata for the assembly. The complete name of an assembly not to be confused with the file name on disk contains its simple text name, version number, culture, and public key token.

Assemblies are considered equivalent if they share the same complete name. A private key can also be used by the creator of the assembly for strong naming. The public key token identifies which private key an assembly is signed with. Only the creator of the key pair typically the person signing the assembly can sign assemblies that have the same strong name as a prior version assembly, since the creator possesses the private key.

Strong naming is required to add assemblies to Global Assembly Cache. Starting with Visual Studio ,. NET Native compilation technology allows for the compilation of. NET Framework includes a set of standard class libraries. The class library is organized in a hierarchy of namespaces. Most of the built-in application programming interfaces APIs are part of either System.

These class libraries implement many common functions, such as file reading and writing, graphic rendering, database interaction, and XML document manipulation. The class libraries are available for all CLI compliant languages. The class library is divided into two parts with no clear boundary: BCL classes are available in.

NET Framework as well as its alternative implementations including. NET Core and Mono. With the introduction of alternative implementations e. With the further proliferation of. NET platforms are encouraged to implement a version of the standard library allowing them to re-use extant third-party libraries to run without new versions of them.

NET Standard Library allows an independent evolution of the library and app model layers within the. NuGet is the package manager for all. It is used to retrieve third-party libraries into a. NET project with a global library feed at NuGet. Atop the class libraries, multiple app models are used to create apps.

NET Core apps by default. Other app models are offered by alternative implementations of the. NET Core are available on. The retroactive architectural definition of app models showed up in early and was also applied to prior technologies like Windows Forms or WPF. NET decompilers such as. NET Reflector reveal only the managed code. Because computer systems commonly require interaction between newer and older applications,.

NET Framework provides means to access functions implemented in newer and older programs that execute outside. EnterpriseServices namespaces of the framework. Because of this feature,. NET Framework supports the exchange of types and object instances between libraries and applications written using any conforming.

NET Framework also enforce type safety. This prevents ill-defined casts, wrong method invocations, and memory size issues when accessing an object. This also makes most CLI languages statically typed with or without type inference. This makes it possible for third parties to create compatible implementations of the framework and its languages on other platforms.

NET Framework has its own security mechanism with two general features: CAS is based on evidence that is associated with a specific assembly.

Typically the evidence is the source of the assembly whether it is installed on the local machine or has been downloaded from the Internet. CAS uses evidence to determine the permissions granted to the code.

Other code can demand that calling code be granted a specified permission. The demand causes CLR to perform a call stack walk: Managed CIL bytecode is easier to reverse-engineer than native code, unless obfuscated.

NET decompiler programs enable developers with no reverse-engineering skills to view the source code behind unobfuscated. In contrast, apps compiled to native machine code are much harder to reverse-engineer, and source code is almost never produced successfully, mainly because of compiler optimizations and lack of reflection.

Labs , Turbo , and Red Gate Software. Method-level encryption tools for. NET code are available from vendors such as SafeNet. CLR frees the developer from the burden of managing memory allocating and freeing up when done ; it handles memory management itself by detecting when memory can be safely freed. As long as a reference to an object exists, which may be either direct, or via a graph of objects, the object is considered to be in use. When no reference to an object exists, and it cannot be reached or used, it becomes garbage, eligible for collection.

NET Framework includes a garbage collector GC which runs periodically, on a separate thread from the application's thread, that enumerates all the unusable objects and reclaims the memory allocated to them. It is a non-deterministic, compacting, mark-and-sweep garbage collector. GC runs only when a set amount of memory has been used or there is enough pressure for memory on the system. Since it is not guaranteed when the conditions to reclaim memory are reached, GC runs are non-deterministic.

NET application has a set of roots, which are pointers to objects on the managed heap managed objects. These include references to static objects and objects defined as local variables or method parameters currently in scope, and objects referred to by CPU registers. It uses CLI metadata and reflection to discover the objects encapsulated by an object, and then recursively walk them. It then enumerates all the objects on the heap which were initially allocated contiguously using reflection.

All objects not marked as reachable are garbage. However, this leaves chunks of free space between objects which were initially contiguous.

The objects are then compacted together to make free space on the managed heap contiguous again. The latest version of. NET framework uses concurrent garbage collection along with user code, making pauses unnoticeable, because it is done in the background. The garbage collector used by. NET Framework is also generational.

Newly created objects are tagged Generation 0. Objects that survive one garbage collection are tagged Generation 1. Generation 1 objects that survive another collection are Generation 2.

The framework uses up to Generation 2 objects. This raises the efficiency of garbage collection, as older objects tend to have longer lifetimes than newer objects. When an application is first launched, the. NET Framework compiles the CIL code into executable code using its just-in-time compiler , and caches the executable program into the. To speed up the first launch, developers may use the Native Image Generator utility to manually ahead-of-time compile and cache any.

The garbage collector, which is integrated into the environment, can introduce unanticipated delays of execution over which the developer has little direct control. Simd namespace in In case the CPU lacks support for those extensions, the instructions are simulated in software. NET Framework is the predominant implementation of. Other implementations for parts of the framework exist.

Although the runtime engine is described by an ECMA-ISO specification, other implementations of it may be encumbered by patent issues; ISO standards may include the disclaimer, "Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

ISO shall not be held responsible for identifying any or all such patent rights. Also, parts of FCL have Windows-specific functions and behavior, so implementation on non-Windows platforms can be problematic. Microsoft managed code frameworks and their components are licensed as follows: From Wikipedia, the free encyclopedia. For the Internet domain, see. For other uses, see. NET Framework version history. It must be installed either from a Windows installation media or from the Internet on demand.

Control Panel always attempts the latter. International Organization for Standardization. Archived from the original on 5 August Retrieved 3 August However, there are several libraries that are included with Mono, and commonly used by applications like Tomboy, that are not required by the standard.
