  1. Refactoring to add a parameter to existing method

    This suggestion is migrated to Developer Community. Please use below link to view the current status.
    https://developercommunity.visualstudio.com/content/idea/351698/refactoring-to-add-a-parameter-to-existing-method.html
    When I type a method call with an extra parameter, the refactoring tools allow me to create a new overload of the method as shown in the screenshot below.

    It would be nice if another refactoring could be added that would simply add the additional parameter to the existing method, instead of creating a whole new overload.

    • Provide an option to disable the Quick Info popup

      Provide an option to disable the Quick Info popup.

      Whenever I hover over a type, variable, object or value, the Quick Info popup appears, hiding the very part of the code I'm trying to view/edit. I've been told by Elvin Zhao that "so far there is no option to disable the Quick Info option popup".

      This is very problematic for me, because I need able to see my code without the (literally) constant distractions of this behavior. I'm getting ready to find another editing environment. Please advise.

      • Support mutation testing for c#

        I run a team that makes extensive use of Pit testing for Java. (http://pitest.org/) This leads to dramatically simpler, decoupled and better tested code. With all the advances of the roslyn compiler, this would be an amazing addition to the c# development experience, plus with the advantages that Roslyn could suggest automatic fixes for many issues discovered

        • option to disable quick action squiggles

          In VS2015 you introduced the quick action light bulb. I think its a cool piece of tech, and I get why many people like it. However its a bit to intrusive for me, the light bulb was ok, but the green quick action squiggle errors are starting to become a bit annoying.

          For example, when I create classes I prefer writing up the class first in the header file, writing the functions, variables etc I know I will be needing. The second I finish writing the constructor prototype the squiggles and the light bulb flare up, "Function definition not found,…

              • Allow SuppressMessageAttribute to work types within a namespace

                Right now the SuppressMessageAttribute only suppresses diagnostics against a namespace, but not the types within it.
                So this:
                [assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Style", "CC0061", Scope = "namespace", Target = "CodeCracker.Test.Design", Justification = "No need for tests to have async sufix.")]

                Would not work against types inside the "CodeCracker.Test.Design" namespace, but only if the diagnostic was on the namespace itself.
                To be able to do that, we need to add a SuppressMessageAttribute to each type individually, what is error prone, ugly and demands a lot of attention.
                There needs to be a way to allow for the suppression of diagnostics agains all types within…

                • Do not indent #region with code

                  In C# the #region's follow the code in indentation. I think this is wrong, as they are not a part of the code, and should stay aside - just like they do it in Visual Basic.
                  I find the C# #region's too obtrusive. Please, change the behaviour, so they are left-aligned in the editor window, both when folded and unfolded.

                  • Add IntelliSense support for the <inheritdoc /> tag in XML documentation comments

                    We currently use the <inheritdoc /> and <inheritdoc cref="" /> tags extensively in our code base in order to reduce the amount of duplicated documentation that needs to be written.

                    This works great for the most part, since we generate our docs using Sandcastle.

                    However, when we are actually developing code in the same c# project as the API which uses <inheritdoc>, Visual Studio does not recognize the tag, or resolve any references.

                    It would be great if Visual Studio Intellisense could actually do this.

                      • Windows Forms Designer Errors

                        https://developercommunity.visualstudio.com/content/idea/351695/windows-forms-designer-errors.html
                        The windows forms designer in Visual Studio still has a lot of critical bugs that need to be fixed.

                        One in particular that I encounter on an hourly basis is:
                        GenericArguments[0], 'ServiceDefinition...IMyObject', on 'Client...BaseForm`2[TService,TImplementation]' violates the contraint of type parameter 'TService'.

                        Here is the call stack:
                        at System.RuntimeTypeHandle.Instantiate(RuntimeTypeHandle handle, IntPtr* pInst, Int32 numGenericArgs, ObjectHandleOnStack type)
                        at System.RuntimeTypeHandle.Instantiate(Type[] inst)
                        at System.RuntimeType.MakeGenericType(Type[] instantiation)

                        The error occurs whenever I change something on the base forms and recompile the project. The only way to get the designer…

                          https://developercommunity.visualstudio.com/content/idea/351721/add-new-feature-to-systemstring-like-typescript.html
                          We can write c# code like follows:
                          string name = "Tom";
                          string hello = $"Hello {name}!";
                          string path = @"D:\images\a.png";

                          Sometimes we want to keep complicated string fromat like Json string, It's very inconvenient. We must write like this:
                          string json = "{\"name\":\"Tom\"}";
                          json = @"{""name"":""Tom""}";

                          But in Typescript, it's very easy:
                          content: string = `{"name":"Tom"}`;

                          So I want to add this feature to c#/.Net.

                                This suggestion is migrated to Developer Community. Please use below link to view the current status.
                                https://developercommunity.visualstudio.com/content/idea/351762/let-interfaces-be-implemented-by-a-field.html
                                The sample:

                                interface IFoo {
                                void DoFoo();
                                }

                                class Bar : IFoo => _foo {
                                private IFoo _foo;
                                Bar(IFoo foo) { _foo = foo;}
                                }

                                Why:
                                - supports aggregation over inheritance
                                - implicit use of the GoF strategy pattern
                                - syntax fits property/method expressions

                                How:
                                - defines an explicit interface implementation
                                - the field is implicitly a non-nullable reference

                                Use:
                                - to modularize behavior and easily aggregate it
                                - to vary the implementation, for instance for testing
                                - to solve annoying things like…

                                • Add static indexers

                                  Altough there was this comment on the very same proposal: "Thanks for taking the time to share this suggestion. This item has been around for a couple of versions of Visual Studio and we haven’t acted on it. Looking at the VS “15” plans, we’re not going to take action on this item, so we’re going to close it. If the suggestion is still relevant, please either take a look to see if there’s another suggestion that’s similar that you can vote on, or open a new suggestion."

                                  I do suggest the very same thing: static indexers.

                                  Currently, indexers need…

                                    Hello,
                                    I am Computer Engineer from Turkey. Graduated From Istanbul Technical University In 2015.
                                    I was Intern at Microsoft Turkey in 2012 and worked at Sony Turkey, Siemens, Asseco SEE..

                                    My suggestion is make Exception Handling or changing signature mandatory..
                                    For example, if I throw an Exception in my method, I must decleare that this method may throws an Exception so a user can see the type of exceptions that can be thrown from this method.

                                    This is the case in JAVA.
                                    Example: …
