  1. Add a constructor to Dictionary that takes a enumerable of KeyValuePair

    I'd like a constructor on System.Collections.Generic.Dictionary<TKey, TValue> that takes IEnumerable<KeyValuePair<TKey, TValue>> to create a populated dictionary.

    • Support syntax if(obj?) insted of if(obj != null)

      The current ? operator should be followed by dot then member
      But if I want to check if the object is null or not I should use normal syntax as:
      if(obj != null)
      {
      // Do something.
      }
      else
      {
      // Do something else.
      }

      or:

      if(obj == null)
      {
      // Do something.
      }
      else
      {
      // Do something else.
      }

      So I suggest to support following syntax insted of it:
      if(obj?) // true if not null
      {
      // Do something.
      }
      else
      {
      // Do something else.
      }

      if(!obj?) // true if null
      {
      // Do something.
      }
      else …

      • nameof for multiple members

        In c# 6
        string name = nameof(Property); // name = "Property"
        string[] names = { nameof(Property1), nameof(Property2), nameof(Property3), nameof(Property4) }; // names = Array of names
        I suggest to support the following syntax:
        string[] names = nameof(Property1, Property2, Property3, Property4); // names = Array of names

        • adding tabbing for including libraries while typing in Visual Studio

          This relation to forum question, https://social.msdn.microsoft.com/Forums/en-US/e892d105-d26c-426d-9edf-9f6b8f0f3a5e/how-to-add-using-to-reference-an-assembly-while-typing-a-known-object-from-a-library?forum=visualstudiogeneral.

          When typing in a know dependency it is required to type ctrl + . to open a mini-dialogue window for options for resolving the error. Currently, doing so would allow for adding the using to the current module if it is missing. I purpose auto complete for such usings given certain conditions would make it obvious to add an using directly while typing something that is not currently referenced.

          • Distributed compilation

            Able to distrubute compilation to more computers. Master computer will make pre-procesing and all others will just make raw C++ compilation. The best would be if the client computers will not require full Visual studio licence.

            • Support debugging with EdgeJS

              It would be nice if i could debug my JS code that is running in a .net process using EdgeJS. Currently the node insepector seems to be the only option to do that.

              • enable single sign on with windows account onto Visual Studio Online and Azure

                It would be very user-friendly if one could pick their Microsoft account identity that is being used for the Windows user session. Why logging in onto your desktop and secondly entering your credentials within Visual Studio? This should be perfect single-sign on federation scenario.

                • User changeable color scheme based on project

                  I often run several instances of Visual Studio at once so I can debug multiple programs that "talk" to each other. It sometimes gets confusing as to which instance, editor, debugger, etc. I'm looking at.

                  I would be helpful to set the color scheme of the IDE based on the project (not a universal setting), so each project that I'm dealing with has a distinct look.

                  • Allow for formal #TAGGING of comments, create a tool that harverst all the #TAGS, summarize and index them, make it easy to jump to the code

                    #TAGS are everywhere nowadays. It would be great to have native VS support for #TAGS, which sumarizes and indexes all the #TAGS in comments. This allows us to do things like #CODE_REVIEW or #REQUIRES_UNIT_TEST or #RISKYCODE. The summary index should allow is to quickly jump to all the methods that need a code review etc. Awesome powerfull feature, quickly implementable!Remeber me in your credits :)

                      • Enable executing Powershell on Azure Web Apps

                        While working on continuous deployment scenarios performing azure tasks on a Web App is quite cumbersome.

                        For example, simply copying files from a storage account to the web app takes too long from VSO. It requires met to add those files to my zource tree. If the files could be copied from the storage directly to the Web App, this would speed things up considerably.

                        I believe there are many more scenarios that would benefit from this feature.

                        • Check for nulls on a cascade of objects

                          Imagine this classes:

                          class A
                          {
                          int myInt;
                          }
                          class B
                          {
                          A myA;
                          }
                          class C
                          {
                          B myB;
                          }

                          class D
                          {
                          C myC;
                          }

                          If I have an object of type D and want to access myInt inside A on a secure way, I would have to do:

                          if (myD.myC != null && myD.myC.myB != null && myD.myC.myB.myA != null)
                          {
                          Now i can use myD.myC.myB.myA.myInt securely!!
                          }

                          Why not just do this check:

                          if (myD.myC.myB.myA != null)
                          {

                          }

                          This should not crash if myD, myC, myB are null, simply because myA can only not be…

                            • MTM - Test Execution State should also reflect iterations level status

                              Assume my Test Cases got multiple iterations and while executing them , I executed only partial iterations and they got passed.
                              Issue - Overall Test Case status comes as passed and does not reflects that some of the iteration execution is pending

                              • Newer versions of Visual studio (say 2015) should be compatible with extensions created for previous versions of VS automatically

                                Not all extension writers will update their extensions all the way along VS's upgrade path. And they shouldn't have to if they don't have newer things to add.
                                However, as a conquence, these extensions won't report compatible with newer versions' of VS. So every time there is a new version of VS, there will be fewer extensions, which is not something that should happen.

                                  We hear you. Unfortunately forward compatibility has proven harder than any of us would like.

                                  Some examples of the complexity here, not as a defense but just in the interests of transparency:
                                  – By default, the extension manifest that is part of the template for new projects in Visual Studio 2015 targets just the current version, which is probably too conservative;
                                  – We changed the signing mechanism between Visual Studio 2013 and Visual Studio 2015 from SHA1 to SHA256 to keep pace with security standards, which meant that older versions show as incompatible;
                                  – The gallery doesn’t automatically show extensions as compatible with the latest version unless the developer marks them accordingly (even if they are actually compatible);
                                  – In Visual Studio vNext, we’ll install less by default – so extensions that thought they were compatible with later versions may be wrong (e.g. we no longer include the C# language…

                                • In solution explorer, add "structure view" for Python

                                  For C#, there is such a feature in solution explorer, where you can expand C# files and view the namespaces, classes, methods, properties in a hierarchy view. See a random picture from web showing the structural view.
                                  It will be nice if there is the same thing for PTVS.

                                  • Unseal System.Web.HttpCookie

                                    It is sealed. Adding behavior to it is a pain, as we need to create a wrapper, and then test, etc.

                                    Why is it even sealed? Please can you unseal it in the next release?

                                    • Enable adding of multiple projects to a solution in one step by adding all projects in the selected solution

                                      We have multiple projects belonging together (interface, implementation, unit tests, integration tests of a component which are separate projects in a component specific solution)

                                      When working on an executable depending on a large number of those components, we would like to add all projects of a component solution to the currently open solution of the executable in a single step instead of having to add the projects individually.

                                      A different approach to our problem would be to drastically increase the performance of Visual Studio when working with a large number of projects (>250 projects) and to be able to define…

                                      • Create a 'using' local variable declaration in C#/VB

                                        (This is described at https://github.com/dotnet/roslyn/issues/5881, but it was requested to be placed here as well)

                                        n C# (and VB), using statements contain an embedded statement (traditionally, a block statement) that contains the code that will be run before the resource is disposed.

                                        When multiple resources require disposal, using statements are nested to accomplish this (though traditionally written at the same level of indentation)

                                        using(var r = new Resource())
                                        using(var s = new OtherResource())
                                        {
                                        }
                                        This works well if all resources can be acquired at the same time, but this cannot always be done. The motivating example, in this…
