I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. One click update of COM wrappers in .NET languages.

    .NET is treating native ActiveX components like legacy but that is how I communicate with my DirectX 11 graphics engine written in C++.

    When using the engine from Visual Basic 6, you get a notification when an update is available and just click to use the new version.

    In Visual Basic .NET however, you can't make any changes to the interface while developing a new version because the wrapper is locked and the easiest way to delete the old version of the wrapper is to delete the whole project and pick modules one by one into a new project since…

    • Please support/extend .Net Micro Framework on existing and new platforms

      It seems that Microsoft has made the .Net Micro Framework Open source because they didn't want to spend time and resources on it. At least that's what it seems from the outside.

      I would like to see the .Net Micro Framework supported as well as continually extended with active participation by Microsoft.

          • Please Put the Checkboxes back on the Check-in Window

            Love having it as a dockable window/panel but the include/exclude and dragging items around is dirty. The checkboxes were just fine. Source control and check-ins is an important operation, simplicity is best. I don't think this is an area to get creative and see how the user base responds, unless the idea is a game changer. This seems like a change just for the sake of changing. I'd also like a little color back in my icons but that's another conversation.

            • Improve SqlBulkCopy throughput

              SqlBulkCopy-based bulk imports are often CPU-bound by CPU-usage inside of the SqlBulkCopy class. This means that bulk copy speeds depend mostly on the implementation of that class. Please optimize SqlBulkCopy for CPU usage so that bulk imports into SQL Server become a lot faster (simply by installing the new version).

              Suggestion: Use runtime code generation to generate serialization code for the TDS data stream. The generated code would be optimized for the specific data types and schema that are being used. Profiling the current SqlBulkCopy class shows that a lot of time is spent serializing data and doing the same…

              • C# to JavaScript, and other suggestions

                1) Microsoft release a new version and new technologies too soon. It makes developer's life a ****. I find myself learning new technologies most of the time rather than using them.
                2) Microsoft should bring in existing opensource projects into visual studio and .net rather than creating it's own. Like Nhibernate instead of Entity Framework. I had spend a lot of time learning and mastering NHibernate and now I have to also start learning Entity Framework. Instead microsoft should have created better tools to integrated Nhibernate with visualstudio etc. or microsoft could support such projects.
                3) Since I love C#…

                • Create base class DbBulkCopy as part of the ADO.NET provider model

                  Presently, SqlBulkCopy offers bulk insertion capabilities for SQL Server. It is one of few classes in ADO.NET that do not follow a provider model, where we have an abstract base class (say, DbBulkCopy) and different implementations for each database engine. Most of these engines already have APIs that offer similar functionality, but it would be useful to have a standard interface to all of them.

                  • ConcurrentDictionary and Dictionary: Please add methods to retrieve original key with value

                    Currently there's no way to retrieve the original key that was in use when value was added to ConcurrentDictionary (same apply to regular Dictionary). Please add overloads that allow to retrieve original key together with the value.
                    For example, today ConcurrentDictionary has TryGetValue(TKey key, out TValue value) and the new overload would be then TryGetValue(TKey key, out TKey originalKey, out TValue value).

                    This functionality is very useful if the dictionary has custom comparator. For example for strings it may be StringComparer.OrdinalIgnoreCase. And then for every string, with different case that matched by comparator, dictionary would report that it has value…

                    • Enhance .NET and COM with New Generic Programming Features

                      1. Enhance CLI/CLR metadata for both templates and generics, including variadic.

                      2. Enhance CLI/CLR metadata for both the partial and full specialization of templates and generics.

                      3. Enhance CLI/CLR metadata for enhanced expressiveness with regard to template and generic parameter constraints. For example, Expression<Func<Type, bool>>[] GetGenericParameterConstraints().

                      4. Enhance type, method and extension method resolution and inference heuristics for compile-time, runtime and dynamic language scenarios.

                      5. Facilitate static interfaces or static interface methods as well as their use in generic parameter constraints and generic method implementations, e.g. T parsed = T.Parse(...).

                      6. Enhance the structure of builtin datatypes for generic programming.

                        • Improve KeyNotFoundException - specify Key and Dictionary names

                          The KeyNotFoundException error message is one of the worst and it needs to be improved. The error message needs to state the name dictionary and the name of the key.

                          Current:
                          System.Collections.Generic.KeyNotFoundException:
                          The given key was not present in the dictionary.

                          Desired State:
                          System.Collections.Generic.KeyNotFoundException:
                          The given key "Ford Fusion" was not present in the dictionary "Airplanes made by Boeing".

                          • Revise shameful MSDN sample code

                            In many cases MSDN sample code is shameful. Look at this: https://msdn.microsoft.com/en-us/library/te15te69(v=vs.110).aspx

                            1. Bad resource usage
                            2. Bad TCP/socket code
                            3. Bad crypto
                            4. Bad error handling

                            This piece of code is representative for what is commonly found on MSDN. In particular all socket code seems to be done by, no disrespect, an intern. If you show such code samples to expert devs at Microsoft they will be ashamed that this code has been put out.

                            This is not good enough. I must have answered hundreds of Stack Overflow questions now from people who have been mislead into bad and…

                            • Restore Support for Reusable ASP.Net Web Form Custom User Controls

                              We support multiple websites. We have some custom user controls that we use on most sites (for example, an employee search tool (that hits a different database with different connection strings)) and some pages that are nearly identical on all websites (for example an 'Diagnosis' page that displays current server info and allows us to test database connections, error processing, error notifications...).

                              In earlier versions of Visual Studio, there was plenty of support and documentation for developing custom user controls that can be used in multiple projects & solutions.

                              Perhaps I am looking in the wrong place for this documentation,…

                              • Allow custom marshaling on arrays in structs

                                For some reason, you can't use the MarshalAsAttribute with UnmanagedType.CustomMarshaler on an array when the array is inside a (sequential layout) struct. The IDE and compiler don't complain, but it will always throw an exception at runtime. This makes it bizarrely difficult to solve problems such as this one: http://stackoverflow.com/questions/5902103/how-do-i-marshal-a-struct-that-contains-a-variable-sized-array-to-c; you have to put the MarshalAsAttribute on parameters of array types (rather than putting it *inside* a struct once, and having the struct contain the array type) and consequently you lose the ability to do things like custom constructors, etc. for your array type.

                                    • Ability to override the configuration system

                                      I know that exists IInternalConfigSettingsFactory. But I can't use this in Web applications because configuration already overrided by HttpConfigurationSystem.

                                      • Make the existing collections implement IEnumerable<T>

                                        All BCL collections that implement IEnumerable should also implement IEnumerable<T>. Example: MatchCollection. Using LINQ requires IEnumerable<T>.
