  1. C# error resistant multithreading – (via visibility and unprotected access protection)

    C# error resistant multithreading – (via visibility and unprotected access protection)
    Making multithreading less error prone: Reducing/Eliminating and detecting unprotected variable access (avoiding many common race conditions)

    Proposal for new C# functionality.

    Multithreaded code is easy to get wrong. A couple of the main concerns are:
    1. Race conditions due to unprotected variable access are easy to introduce/detect
    2. Deadlocks due to lock ordering
    3. Livelocks, lock contention, etc.

    This proposal addresses areas related to problem #1. It does this by helping to make multithreading decisions about which synchronization objects are protecting which code elements more visible. Currently when using…

    • PWA template for Polymer 2 and 3 with ASP.NET Core

      Polymer and web components play main role in creating awesome progressive web apps.
      Visual Studio 2017 should integrate with Polymer to give it the templates already present in polymer-cli.
      Also ASP.NET CORE 2.0 already has templates with angular and react, polymer should also have templates with asp.net core 2 with pwa stuff included like service worker e.t.c.
      Lots of developers want to develop in visual studio and with asp.net core 2.0 because of easy identity system ( azure ad b2c integration ) and easily publish to azure, so we need these features along with easier polymer pwa apps development.

      • Restore global.json functionality in VS2017

        Before the switch from project.json back to .csproj files, I was able to use global.json in order to specify local source code for a NuGet package I referenced. This made it incredibly easy to debug against the source code, and also make code changes on the fly to my dependencies that are in other packages and repositories.

        With the new csproj format, I am forced to make changes to my package and push them up to our registry, or package and push to a local nuget source. This makes for an incredibly clunky experience when NuGet is your primary method…

        • Integrate Conan.Io package manger into visual studio

          Conan.IO is a platform neutral package manager for C++.
          It is the only package manager that can handle the packages in a compiler and platform neutral way. Nuget and vcpkg are only available on windows.

          The problem with conan.io is that there is an effort to learn it. This effort could be improved if there would be an integration into Visual Studio.

          Something like the nuget integration would help a lot.

          Here a presentation about conan.io

            • Fix the UWP designer errors

              I've been doing XAML for 9 years, but the current status of XAML designer in UWP apps is just terrible. Either remove it completely or make it at least as stable as WPF designer in VS2015.

              Things like:

              Method not found: Void Windows.UI.Composition.Visual.put_Size(System.Numerics.Vector2)

              or COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.

              I haven't met a single UWP developer who wasn't frustrated by the designer always broken

              • Support __forceinline on C++ lambda expressions

                clang and gcc both have supported force-inlining lambda expressions for years, but in Visual C++ there's still no way to do this.

                I've attached a sample cpp file to illustrate the problem. Or view it interactively here: https://repl.it/LM8G/11

                Because a lambda is just a class with operator(), and we can manually define such a class having the operator() forceinlined (as in the above workaround), I see no reason why VC++ could not support forceinlining a lambda.

                Of course, in the above example the compiler will probably be smart enough to inline the lambda anyway. And I understand that inlining sometimes…

                • Visual Studio 2017, C#, Mono Cross Platform Linux?

                  So what is the method to use Visual Studio 2017 (or 2015) to develop & build a cross platform desktop GUI application with Linux? The advertising all indicates Xamarin is the way to go...You go to Mono website and the current pages indicate to no longer use monodevelop on Windows, and point to downloading / install Xamarin to VS. I know Xamarin is now Microsoft and built on Mono, so that sounds reasonable. OK, install Xamarin to VS2017 - except nothing there indicates that it works with Linux / Mono... just Android / Apple, etc.

                  • Add "TODO" from TypeScript files in the task list window

                    Hi,

                    it would be nice that TODO contained in ts file were included in the "Tasks List" window.

                    Thanks

                    • Better debugging of object initializer blocks

                      Object initializer blocks allow you to assign property values at construction despite the constructor not accepting the values to assign. This is useful for thread safety because the object is assigned a pre-built instance in an atomic operation. In addition is the only way to initialize an anonymous type. But debugging object initializers are cumbersome at best, impossible at worse. Take, for example, the following code (also attached as bitmap showing line numbers):
                      var book = new
                      {
                      Isbn = isbn,
                      Title = service.GetTitle(isbn),
                      Author = service.GetAuthor(isbn),
                      Edition = service.GetEdition(isbn),
                      PublicationDate = service.GetPublicationDte(isbn),
                      Copyright = service.GetCopyright(isbn),
                      Publisher = service.GetPublisher(isbn),
                      PageCount…

                              Can you stop installing an MSI based (old) version of Azure PowerShell cmdlets. Either stop installing, or give me the option to use a repo, such as PowerShell gallery, where the latest modules exist. Apart from changing the $env:PSModulePath, I can't use PowerShellGet cmdlets to update Azure cmdlets. I also notice one of you updates REMOVES the PS Gallery modules and reinstall the old MSI version. Grrrr!!!

                                • automatically generate precompiled headers

                                  Hi, i noticed a project made by an intern at microsoft which can automatically generate precompiled headers for a project. according to Andrew Pardoe it got removed, because of too many issues. See: https://channel9.msdn.com/Shows/C9-GoingNative/GoingNative-35-Fast-Tips-for-Faster-Builds#time=13m03s

                                  If think the tool mentioned in the above demo has almost all the perks required for such a tool. It can dramatically speed up compile times (which i already noticed when adding them manually). Even if it is not 100% perfect you can easily use it as a base to improve upon.

                                  • Pressing F5 on a test project should run tests in Test Explorer

                                    This has been suggested before, but didn't get enough votes - Let's see if we can ********* the radar this time!!! (https://visualstudio.uservoice.com/forums/121579-visual-studio-ide/suggestions/11317458-pressing-f5-on-a-test-project-should-run-tests-in)

                                    Right now if you Start a unit test project through F5, you get an error dialog stating that "A project with an Output Type of Class Library cannot be started directly."

                                    (Oddly enough, I get caught by this every time - Maybe I'm not writing enough tests!!!)

                                    A nice solution would be to set the Start action on unit test projects to the same action as Debug Selected Tests, and open the Test Explorer if it…

                                        • VS 2017 publish tool

                                          In VS 2017 there is a new Publish tool. But in this tool it is not possible to unselect some files. It is always publishing ALL files.
                                          In the old publish tool you could select Preview and them unselect some of the files. But in the new tool the Preview windows is not connected with the Publish windows, so unselecting in the Preview has no effect.
