    • Starting then running all unit tests in a solution can take a very long time.

      We have over 200 projects, 2900+ unit tests. It takes over a minute some times to get to the point where it can start listing all the unit tests in the test window, and start executing. We have latest gen Core I7, 8GB 64 bit windows, and it is still a pain. Maybe this area needs 're-imagining', as I can understand the complexities of managing this large number of projects/tests, but it is not working well for us.

      • Let lambdas with a statement body be converted to an expression tree

        The C# compiler supports translating a lambda expression to an expression tree (System.Linq.Expressions).

        Today lambdas with no statement body (only a single statement) are supported just fine.

        Expression<Action> x = () => Console.WriteLine("Hello World");

        But lambdas with a statement body (braces), which is needed to have multiple statements, doesn't compile.

        Expression<Action> y = () => { Console.WriteLine("Hello"); Console.WriteLine("World"); };

        I believe there is a lot of awesome stuff not being possible due to this lack of support.

        It seems very unproblematic to implement, but if there are any hidden issues with this feature, it would be nice to know so…

        • Add shortcut to quickly open / close CodeLens function

          In Visual Studio 2013 Preview,
          CodeLens function is very powerful, but when we want to close or open it ... set step is too much. ( see Q&A : http://msdn.microsoft.com/en-us/library/vstudio/dn269218(v=vs.120).aspx )

          Add a shortcut, when we need it just "click (shortcut)" and show it, when we close is same.

          • Make Visual Studio per-monitor/multi-monitor DPI aware

            http://msdn.microsoft.com/en-us/library/windows/desktop/dd464646
            http://imgur.com/qAiVw1Q,eVRIBlZ

            When dragging VS 2013.1 Express to my second monitor running at a different DPI, it becomes blurry. VS seems to be acting as if it only has support for global DPI settings instead of per-monitor settings. It would be great if VS followed the same guidelines its users are attempting to follow when it comes to developing desktop apps ;-).

            • Don't close all files when a project file is edited

              When a project file is edited on the file system (e.g. source control pull), you'll currently get a prompt: "The project '<name>' has been modified outside the environment"

              My options are to not reload, often not being able to compile, or reload the project closing everything I have open...even if it's completely unrelated to the project change (added image files for example). This causes a huge productivity loss on a rapidly iterating project (Stack Overflow in this case), I have to reload the project then spend time opening/searching for whatever I was working on before it happened. In most cases…

              • "View White Space" should show line endings too

                As described here: http://connect.microsoft.com/VisualStudio/feedback/details/621096/view-white-space-should-show-line-endings-too

                Request:
                * Visual Studio > Edit menu > Advanced > View White Space.
                * Currently, this feature shows a symbol for space and tab characters.
                * I would like to be able to view line endings too.
                * I would like to be able to view what style of line ending was used.

                And that's it for the request.

                And now I offer some suggestions as to how this may look. Here's what I've seen other tools do:
                * TortoiseMerge uses a single, unobtrusive symbol. It is "light" and does not distract from the main document…

                • Make go-to-definition and find-references work between F# and C# projects

                  In a solution containing a mixture of C# and F# projects, go-to-definition does not work when your starting point is, say, C# and the target function/value/type definition is in F#. (And vice versa.) The same is true for find-all-references.

                  This is a major inconvenience when working on this kind of mixed codebase. It would be great if it could work in both directions but even go-to-definition would be a great start.

                  • Stop Autoformatting my code

                    Visual Studio has always had options to stop the editor from autoformatting our code. They are found in Options > Text Editor > C# > Formatting > Defaults.

                    In Visual Studio 2015, you decided to add a bunch of new actions that cause Autoformatting to happen. And you didn't add the option to turn it off to this screen.
                    Some of the cases where it now happens:
                    - When I press colon
                    - When I press {
                    - Some cases with the using block.

                    It would be even better to just have a NEVER autoformat my code option - And…

                    • Start developing the Windows API Code Pack again

                      Back in the Windows 7 timeframe, Microsof gave us the "Windows API Code Pack", as a way of using some of the new Win 7 APIs from .Net.

                      It was really useful, but (like anything) it had some bugs, and was missing some useful features.

                      Unfortunately it seems to have been abandoned by Microsoft, with no release since August 2010, and the website moved to the "archive" site:
                      http://archive.msdn.microsoft.com/WindowsAPICodePack

                      Please bring it back!

                      NuGet seems like a perfect vehicle for distributing a package such as this, so that API bindings can ship alongside OS releases (or not), rather than being…

                      • Give option to search only in uncommented code

                        When searching for a string in a project's source code, I often find myself wasting time examining lines that have been commented out. it would be useful to offer an option to return only lines that are not commented out, so as not to confuse the results.

                          • ISO C++ wrappers for WinRT

                            Now that WinRT has been unveiled, a lot of people have criticized the C++/CLI-like quasi-C++ that is the recommended way to interface with the API. And honestly, it looks reasonably nice. If we're willing to give up all hopes of using another compiler than VC11, and don't mind non-standard code in our C++ application, it seem a nice way to interface with WinRT.

                            But how about an alternative?

                            How about offering a "best effort" library-only ISO C++ wrapper to make WinRT usage as simple as possible without relying on library extensions? It doesn't have to be as clean and pretty…

                            • Rename Visual Basic to B# and Support B# With Absolute Parity

                              Dotnet 2015 made it clear: VB.NET developers need to switch to C# or be left behind. Very sad.

                              VB syntax is friendlier, easier to read and code and maintain. Yet Microsoft is killing off this superior language bowing to pressure from myopic C# developers and Mono.

                                  • Compliable strings

                                    If you're writing a tracing and logging component you may well want to pass the current method name to your logging component. Rather than hard code it (then forget to change it when you change the method name) you can use reflection and the MethodBase class to retrieve the name:
                                    System.Reflection.MethodBase currentMethod = System.Reflection.MethodBase.GetCurrentMethod();
                                    System.Diagnostics.Debug.WriteLine(currentMethod.Name);
                                    System.Diagnostics.Debug.WriteLine(currentMethod.DeclaringType.Name);
                                    System.Diagnostics.Debug.WriteLine(currentMethod.DeclaringType.Namespace);

                                    In C # 4.5 you can use attributes System.Runtime.CompilerServices.CallerMemberNameAttribute, System.Runtime.CompilerServices.CallerFilePathAttribute and System.Runtime.CompilerServices.CallerLineNumberAttribute for such purposes.

                                    Frequent use of reflection dramatically reduces performance. Using special attributes is a contentious issue. Because attributes inherently are declarative. They obviously do not provide full support for the…

                                    • Replace Action Recordings in MTM with Xamarin Test Recorder

                                      Action Recordings (https://msdn.microsoft.com/en-us/library/dd286647(v=vs.110).aspx) are nearly useless and are very fragile. Instead Xamarin Test Recorder https://www.xamarin.com/test-cloud/recorder should be integrated into MTM (Microsoft Test Manager) and extended to work with WPF/Win Form/ Desktop applications that require automated testing.

                                      • Restore usability of the new Error List window in VS 2015

                                        1. Restore the ability to sort all entries by their addition time ("Default Order" in VS2013 and older). In VS 2015 RC, messages keep "jumping" as they are generated, which makes it nearly impossible to work with the Error List during a long build without stoping it.

                                        2. Restore (at least as an option) full clearing of Error List on build start, or at least add a button or context menu option to clear it manually. It is very confusing in VS 2015 RC when fixed errors and warnings stay there for half of the build process until the compiler…

                                        • Editor support for italics fonts syntax highlighting

                                          The VS editor should support italics for syntax highlighting.
                                          Why bold, but not italics?
