  1. Overload methods with Generic Type Parameters which require typeof(SomeClass)

    There are many methods available in .NET:
    (PriceEnum)Enum.Parse(typeof(PriceEnum), stringValue);

    Instead of using typeof(PriceEnum) (and casting it to the correct enum)

    A much more prettier approach is by using the following syntax for example:

    Enum.Parse<PriceEnum>(stringValue);

    This calls out for all types of methods which require typeof(SomeClass)

    • Cortana API for web applications

      Right now cortana is available for win phone apps and with windows 10 she'll come to desktops too. But why restrict her to native machines. Unleash her into the internet by providing API to integrate cortana into web applications with asp.net, mvc etc. This way it would change the way web is used. Cortana could be every where and users can browse through applications or look for content even if they don't know the navigation or use any other capabilities that the developer enables. Also that way she could be even an avatar like feature to help users and will…

        • Allow aggressive AOT and adaptive compilation for numeric code

          Numeric code is not compiled as effectively under .NET as it could be -- few vector operations, value-types are less often inlined, etc. For aggressive scientific programming, this should be updated, and oft-executed functions should be optimized as they run.

          • Be convenient when an assembly cannot be compiled because it is currently used by another process

            Let at least the user know the name of the process holding the assembly, and even better, proposes to the user 1) to see the process Window (set it as foreground) 2) to kill the process.

            • Include .NET 3.5 in the Windows server 2012 distribution

              The Windows 8 and Windows 2012 OS images don't come with .NET 3.5. it can be installed as a role, but only if you have internet access from your server. You can't install the standalone distribution of .NET 3.5 - you can only install it via Windows update.

              I know it's now been replaced by .NET 4 but many Microsoft products need ASP.NET 3.5 as a prerequisite. Not having it in the OS installation - but treating it as an operating system component that mist be installed via Windows Update makes it extremely difficult to setup a server that doesn't…

              • Simplify the recommended disposition pattern

                Since the introduction of SafeHandle, declaration of a finalizer in a non-handle class should be exceedingly rare. However, the recommended disposition pattern (as documented at http://msdn.microsoft.com/en-us/library/fs2xkftw.aspx and as verified by static analysis rule CA1063) "caters" to finalization by declaring the virtual Dispose(bool disposing) method.

                In order to simplify the work of implementers, please consider adjusting the recommended disposition pattern for the overwhelmingly common non-finalizable case to include only a single Dispose() method, as opposed to both the Dispose() and Dispose(bool disposing) methods. (See http://msmvps.com/blogs/calinoiu/archive/2010/02/03/what-s-wrong-with-the-net-design-guidelines-dispose-bool-disposing.aspx and http://msmvps.com/blogs/peterritchie/archive/2013/01/20/the-dispose-pattern-as-an-anti-pattern.aspx for additional details.)

                • Enum should implement IComparable<T> and IEquatable<T>

                  Enum implements IComparable and IEquatable but not the generic versions of those interfaces. This means generic methods for enum must use the non-generic interfaces in the constraints, requiring the generated code to do boxing/unboxing which is really unnecessary.
                  E.g. (an extension method):
                  public static bool IsBetween<T>(this T value, T lowerBound, T upperBound) where T : IComparable<T>
                  {
                  return lowerBound.CompareTo(value) <= 0 && value.CompareTo(upperBound) <= 0;
                  }
                  this cannot be used with enum unless it were IComparable instead of IComparable<T> and then .CompareTo would do boxing.

                    • Reload Project From Different Path

                      I sometimes refactor a project structure when I discover there is a parent folder to the solution folder with the same name as the solution folder and the project folder so you end up with:

                      c:\Projects\Project Name\Project Name\Project Name\

                      I copy the code in Windows Explorer to a temp folder, delete the unneeded parent folder and paste back the solution folder so now the path for the project is:

                      C:\Project Name\Project Name\

                      And in Visual Studio the only option is remove project, which removes all the references to that project.

                      It would be really nice if the project wasn't found,…

                      • Entity Framework Data Model Could Generate Navigation Properties For Existing Alternate Keys

                        When updating data model from database, Entities should also retrieve foreign key constraints defined on alternate keys, not only on primary keys. This kind of constraints shoud be tranlated to navitation properties. A lot of legacy databases use this feature and can't be changed on production systems.

                        • Until a decision is made to release a form of Dundas gauge controls provide licenses to all of us orphaned developers.

                          Provide a means to license the Dundas gauge controls since there is no decision to release the gauge controls Microsoft purchased. We can with some work convert from the Dundas chart to the Microsoft Chart controls in datavizualization. We are orphaned on the gauge controls because Dundas can no longer sell licenses and Microsoft has not decided to release the gauges. Not a good thing. It would cost little to at least offer an as is license to the old Dundas gauge controls until a decision to release a version of them was made.

                          • Allow Visual Studio IDE ability to display IL generated code for methods to discover unintended boxing or other performance insights.

                            The only way to look at generated IL code is to compile the binary and run ILDASM. The problem with this strategy is it's not integrated. Moreoever, it locks the binary so you have to exit ILDASM, recompile your change, then there relocate the method you're inspecting (sometimes a good many steps).

                            So many times, little things are hidden like unintended boxing and calls to the wrong implementation's function that would be revealed with this view. There are also times when you really do care to see how the optimizer behaves.

                            • Learn from Smalltalk, the most productive and easy-to-learn programming environment

                              The dynamic language runtime should be extended to support block closures and other truly dynamic language features.

                              All of the really useful advances in C# and Java, over C++, come from features Smalltalk has had for years. Examples include garbage collection, mature class library with re-useable generic code (e.g Collections, Dictionaries...). It comes down to "the right tool for the job." C++ has it's place, like Assembly has its place.

                              Steve Jobs first saw the mouse and windows on a screen at Xerox Palo Alto and got the idea for the Lisa (which became the Mac). That was Smalltalk he…

                                Dear Microsoft:

                                Thank you very much for all the effort you have been puttin into providing the development community with great tools. I have been using Visual Studio and team foundation service and I love it. It has changed the way I do things. There is still something missing. I work with a group of Open Source entusiasts. Most of them have mac computers. As a matter of fact, I still have not worked with any interface designer that does not own a Mac. I keep trying to make them move to .Net. Azure and TF service are great incentives…

                                • Add ability to sort collection by property value using linq lambda expression

                                  Allow us to sort a collection using lambda.
                                  Currently the list.sort method works ok for list of string or ints.
                                  But it is not flexible for a custom object e.g customer.
                                  Please allow the following syntax to sort by the specific property values

                                  e.g. C#
                                  customers.Sort(customer => customer.FirstName, customer.LastName)

                                  VB.NET
                                  customers.Sort(function(customer) customer.FirstName, customer.LastName

                                  • Better PC speeching with more localized voices (Italian too!)

                                    Now there is a problem to find localized voices in Italian for PC speeching.
                                    I think it's a good idea to implement the speech functions in the .NET Framework and insert more and more localized voices in VS resources.

                                    • Allow custom format strings for boolean values

                                      I would like to be able to specify how string.Format displays the True and False values of Boolean variables.

                                      For example I would like the following C# snippet to output "Boiler: On" rather than "Boiler: True":

                                      bool boilerIsOn = true;
                                      Console.WriteLine("Boiler: {0:On:Off}", boilerIsOn );

                                        • Please create a .Net3.5 off-line install package that can be used with Windows 8.x.

                                          I have been trying to install Windows 8.1 Embedded via SCCM 2012 R2 and I cannot get it to enable .net.35

                                          I've tried via an autoinstall.xml file and dism. Short of copying the sxs folder from the instal media so they are available to dism I cannot get it to enable .net3.5.

                                          Note the client being installed DOES NOT have network access.

                                          A solution such as teh .net4.5 offline install program would be ideal
