Visual Studio IDE

Announcement: Last fall, we migrated this forum to Visual Studio Developer Community to provide you one convenient and responsive system for all feedback. As the final step in the migration, this forum will be closed off completely on June 1st, 2019. We encourage you to visit Visual Studio Developer Community where you can now suggest new ideas, browse and vote on existing ideas, and engage with Visual Studio teams.

We’d like your suggestions and ideas to help us continuously improve future releases of Visual Studio, so we’ve partnered with UserVoice, a third-party service, to collect your feedback. Please do not send any novel or patentable ideas, copyrighted materials, samples or demos for which you do not want to grant a license to Microsoft.

This site is for feature suggestions; if you need to file a bug, you can visit our Developer Community website to get started.

Note: your use of the portal and your submission is subject to the UserVoice Terms of Service & Privacy Policy and license terms.

We look forward to hearing from you!

I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Add "?." operator to C#

    Add the "?." operator to C# and make it chainable like CoffeeScript so we don't have to write null reference checks for every nested property. An example would be:
    myObject?.Items?.[0]?.DoSomething()

  2. C# and SIMD

    It would be great if C# compiler and .Net JIT compiler could utilize SIMD instructions of current and future processors. The projects that require heavy calculations (MathDotNet.Numerics for example) would greatly benefit from this feature.

  3. I wish catch multiple exceptions in the same catch

    For example:

    try
    {
    // smth}
    catch (RemoteException, NamingException , CreateException e)
    {
    // smth
    }

    I’m going to mark this as completed. Even though the feature we ended up implementing didn’t do exactly as requested here.

    Instead we added exception filters to C# in the CTP of Visual Studio “14”. They provide an easy solution for this scenario, and addresses the core issue raised by many, namely what is the type of e.

    For this scenario you’d use it like this:

    try { … }
    catch(Exception e) if (e is RemoteException || e is NamingException || e is CreateException)
    {

    }

    You can find links to the CTP and more info about the upcoming C# language features at this CodePlex post:

    Thanks for the great ideas and discussion!

  4. Allow "default" values on automatic properties

    When using auto-properties, I should be able to set a default value without having to create a constructor, like I can with a field:

    Something like:
    public bool IsActive = true { get; private set; }

    We’ve now added initializers to auto-properties, which addresses this scenario. Additionally we are allowing getter-only auto-properties.

    These additions can be tried out in the CTP of Visual Studio “14”. For links to that, and details about the new C# language features, please check out this CodePlex post:

  5. String interpolations in C#

    Enable string interpolations in C#.

    The interpolation should happen during compile time, so there are no performance penalties paid during runtime.

    The Boo implemenation is a good place to start:
    http://boo.codehaus.org/String+Interpolation

    These should work:

    var a = "Now is $(DateTime.Now)."
    var b = "Tomorrow will be $(DateTime.Now.AddDays(1))"
    var c = "This list has $(list.Count()) items."

  6. Add nameof operator in C#

    Add a nameof operator in C# like typeof operator.
    Syntax:
    nameof(<TypeName>),
    nameof(<TypeName>.<MemberName>)

    It is really required for maintenance as refactoring enabler.

    It is wished for notify property change.
    I have heard about the CallerInfo attributes BUT here is the key example that show that only a nameof operator will solve all the needs:

    We need it in order to fill attributes:
    [GlobalizedDescription(typeof(CommonResources), nameof(CommonResources.MyProperty)]

    MEF property or method contracts are also obvious example

    In the latest CTP of Visual Studio “14” we have added the nameof(…) operator to the language.

    It is indeed great for INotifyPropertyChanged, but also for ArgumentNullExceptions and various reflection scenarios.

    Find links to the CTP and more details about the new C# language features on CodePlex:

    Thanks for the great input!

  7. Compilation responsivness and enhancement

    C# and VB.NET compilers are blazingly fast! However, on RebuildAll scenarios, the user experience could be (easily) enhanced if:

    1) The progress bar would show accurately the RebuildAll progression.

    2) If before compilation, VS could warn/break if one or several target DLLs WndHandle are currently hold by some processes, and which process hold which handle (the process explorer way)

    3) RebuildAll doesn't try to recompile DLLs relying on DLLs that didn't compile successfully.

  8. Compile c# to native code directly, not to IL code.

    C# is a very beautiful language. But ,net framework is a very very slow framework, need to many memory.
    So please Compile c# to native code directly, not to IL code. base on winrt and win32 directly.

    The Visual Studio 2017 Build Tools (version 15.7) include the Static Analysis tools and the legacy FxCop. However, we recommend that you use the .NET Compiler Platform (“Roslyn”) Analyzers, version 2.6.0 or later, which are available here: https://github.com/dotnet/roslyn-analyzers#recommended-version-of-analyzer-packages. You can find more information on using the Analyzers here: https://docs.microsoft.com/en-us/visualstudio/code-quality/roslyn-analyzers-overview.

  10. Make Roslyn scripting able to import files (like #load)

    Make it possible to load a script file from another scipt file, and be able to call the functions in the loaded script. Just like #load does in the interactive window. http://stackoverflow.com/questions/13556859/how-to-load-referenced-script-libraries-from-a-roslyn-script-file

  11. discard the terrible slow .net framework, let c# compile to a native code vm, just like vb6, best let c# run on vb6 runtime.

    .net framework is terrible slow. microsoft's product like dynamic crm is terrible slow and eat terrible memory! visual studio is terrible slow and eat terrible memory! just because .net framework is very bad..net framework can't Compatibility to each version and cant't cross-platform, so .net framework is a joke. .net framework will kill microsoft.
    So please dicard .netframewok and goto native code framework, just like vb6.
    the best choice is bring back vb6, and let c# run on vb6 runtime directly.
    thanks!
