  1. Support Data Breakpoints for C#

    Data Breakpoints are very useful when debugging state issues as they break into the debugger when the value of a variable changes.

    It is currently only supported in C/C++

    Please extend support to C# and the other managed languages. We need it badly. The reason there is no uservoice suggestion is that most NET Developers don't know it exists in C++

    • Faster thread loading PDBs and fetching PDBs from the symbol server

      Loading PDBs is incredibly slow especially when fetching from a remote symbol server. It should be possible to thread loading of the symbol files for all of the load time DLLs (i.e. those loaded before the first instruction executes). It would also be great when debugging minidumps (since all of the loaded DLLs are known ahead of time)

      • Add IntelliSense for Node.js scripts and AMD modules

        WebMatrix has good IntelliSense support for Node.js server-side code.
        It can even resolve exported functions from other module using require().

        Can this be added to Visual Studio's Javascript IntelliSense engine?

        • Allow delegates and generics to be used in attributes

          Alter section 17.1.3 of the C# language specification to allow for additional language features to be used in attributes. For example, being able to specify a delegate (anonymous or not) would allow one to look up a member-specific validation method using a static method:

          public static bool NameValidator(string name) {
          return !string.IsNullOrEmpty(name);
          }

          [StringValidation(NameValidator)]
          public string Name { get; set; }

          One better would be to allow anonymous delegates or lambda expressions:

          [StringValidation(str => !string.IsNullOrEmpty(str))]
          public string Name { get; set; }

          Better yet would be to allow for generics in attributes:

          [Validation<string>(str => !string.IsNullOrEmpty(str))]
          public string Name { get;…

          • Add Report Controls to WPF toolkit

            One of the missing feature of WPF is that it it does not have report controls in the toolkit. Because most applications are data driven and in LOB apps report is indispensable.

            • Split VS11 windows horizontally and vertically the at same time.

              It would be nice if you could split VS11 windows horizontally and vertically (read: create a vertical tab group on a horizontal tab group and vice versa) the at same time as display size increases constantly.

              So you'll be able to have a arrangement of your files like http://jsfiddle.net/ provides.

                • implement branch history for folders

                  In the history of a single file the branch/rename history is visible by plus-sign on the left.
                  I would like to have such a feature for complete folders which are branched/renamed.

                    Thanks for the suggestion – we’re currently investigating what it would take to enable a better folder history experience inside Visual Studio. We’ll provide more updates as we better understand this work.

                  • Enable Go To Definition (F12) should go to source if source symbols are available

                    Right now, source code integration for framework sources (or any other source-indexed PDB) is clunky. You have to be in a debug session for it to pull down the source.

                    If you're not in a debug session and use Go To Definition/Ctrl-Click/F12 on a Type/Method/Property, it'll take you to the object browser, or a code view that shows just the signatures.

                    I propose that VS check for a source PDB in the symbol path first, then if available, use the source code directly. This would be an option, of course, so people can retain the current behavior. It would also…

                    • 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.

                        • Drag and drop reordering for multiple consecutive items in the product backlog

                          In hosted TFS 2012 preview it is possible to reorder the product backlog by dragging and dropping, for one item at a time.

                          When your product backlog is large and you have several consecutive items to move this can be quite time-consuming and fiddly to achieve. It would be great to be able to select multiple items and drag them all together to a new position.

                            VS 2012 Ultimate RC does not seem to have any support for the Data Compare feature that was present in VS 2010 Ultimate and that saved me a ton of time (not to mention cash) when comparing the data between 2 databases and generating deployment scripts.

                            With regard to database diagrams, these were also supported in VS 2010 but do not seem to be supported at all in VS 2012, diagrams are useful way to quickly see the structure of a database and yes I know I can use SSMS but as this is built on top of VS 2010…

                              • 'params' keyword for every list

                                If you're a C# developer, I bet you've used something like this before:

                                ***** SomeType DoSomething(params AnotherType[] array){...}

                                It is a lot easier to use the 'params' modifier than to create a new array with all the paremeters of the same type you want to insert in a method, specially when it comes to small test projects.

                                However, using this comes with a disadvantage: you MUST use the array type. No IList, List<T>, Dictionary<TKey, TValue>, etc.. I believe there is no such reason not to allow these list-like types to use the params keyword. Example:

                                ***** SomeType DoSomething(params ListType list){...}

                                  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.

                                  • Automatically handle thread dispatching when binding to ObservableCollection.

                                    If you use MVVM today you have to wrap your collection to handle dispatching, which makes it much more difficult to have pure view-models.

                                    • Move a file in TFS, which is dragged from on project to another instead of remove and add it

                                      Until now, Visual Studio removes and adds a file in the TFS if it get traged/moved between different projects. Visual Studio should move the file instead to prevent the CC history.
                                      The same could also be used for cut & paste a file.

                                        Thanks for the suggestion – we’re currently investigating what it would take to enable a better move experience across projects in Solution Explorer. We’ll provide more updates as we better understand this work.

                                      • support arithmetic operations on Blend numeric textfields

                                        why not support arithmetic operations on numeric textfields, it can add a real plus-value to the tool and can improve the productivity of the designer/developer

                                        example:

                                        24*7

                                        480/3

                                        240*0.8

                                        24*2+200

                                        • Set the default for "Run when build error occurs" to "Do not launch"

                                          The remarkably useless option to run the old version when a build error occurs is the first VS prompt a user sees when there is a build error for the first time after installation. It is annoying especially because it is totally useless but recently I started teaching programming to beginners and this option is a BIG issue. Most people are used to checking the "don't bother me anymore" checkbox and then clicking "yes" on dialogs. You can imagine the mess this causes for a beginner who doesn't even know why his changes (which do not compile) do not affect…
