  1. Allow image map in asp.net to assign colors or images to hot spots

    Asp.net image map does not contain the functionality to assign colors to the hotspots created by the user. This feature will be very use full when dynamically assigning the hotspots.

    • add BitScanForward and BitScanReverse functions to .NET Framework, like in C++.

      The .NET Framework seems to be missing functions to give us safe access to the BitScanForward and BitScanReverse x86 instructions, for 32-bit and 64-bit integers.

      Following you can see the C/C++ functions documented but there is no C# or .NET equivalent.

      http://msdn.microsoft.com/en-us/library/fbxyd7zd(v=vs.100).aspx

      If you are bothered by the fact that BitScanForward returns 2 values (boolean and index), or if you wish to make the name less ambiguous than "BitScanForward", then you could make a slight modification as follows and name it "CountTrailingZeroBits".

      int CountTrailingZeroBits64(UInt64 inValue)
      {
      int i;
      return _BitScanForward64(&i, inValue) ? i : 64;
      }

      And similarly for…

      • Please update the System.Reflection.StrongNameKeyPair to work with .pfx files

        Currently signing with a .PFX programatically requires that one either use the Process class to run sn.exe with flags, or some classes from Mono to sign an assembly from code.

        I am suggest that the current implementation be expanded to process the .pfx files as well. I do not like having to use .snk if I am signing from code, it leaves the private key exposed and vulnerable.

        • Make the WPF WebBrowser control more customizable by making the virtual method CreateActiveXSite accessable

          WPF contains a WebBrowser class which is a nice wrapper for the native ActiveX control. For customization of the browser an ActiveXSite object is assigned to the browser control. The interface IDocHostUIHandler for example, is used in the internal WPF class WebBrowserSite.

          The browser control also allows customization using other interfaces, IServiceProvider for example. The classes and methods required to inject these customizations are 'internal' to PresentationFramework assembly. Therefore it is not possible for others to customize the browser control.

          The WebBrowser control class of Windows Forms is a good example of how it should be. That class has a…

          • Implement Lists / Arrays with long indexes (64-bit)

            Hi Guys,

            A fair number of us out there in virtual space would be very happy if you would implement support for Array / Lists with the use of a long data type as the index. This is kind of a problem that is brought up continuously on StackOverflow.com, and we are seriously lacking a GOOD solution here. Yes, we've heard that you've increased the supported size in the .Net 4.5 Framework, but it's not good enough. We really want to be able to use the 64-bit space for addressing more than a few billion objects, and this lack of…

              • Allow non-primitive types for WCF Data Service service operations.

                http://msdn.microsoft.com/en-us/library/cc668788.aspx states:
                "If parameters are defined, the type of each parameter must be a primitive type. Any data of a non-primitive type must be serialized and passed into a string parameter."

                It would be really useful to be able to pass through non-primitive types into service operations, manually deserializing non-primitive types as a workaround is quite messy as support has to be added for both JSON and XML formats (to keep it consistent with the rest of the API). Something similar to MVC model binding would make this painless.

                • add option to save/open request in WCFTestClient.

                  It would be very useful to have the option to save a request for service methods with large request objects in the WCFTestClient. For small request objects it is not difficult to rehydrate a request. Large requests objects can take an hour or more to fully hydrate. The "Open request" option should be fault tolerant to changes to the service contract (i.e. ignore properties that have been removed/change).

                  • TaskFactory.ContinueWhenAll should not throw ArgumentException when passed an empty array of Tasks

                    TaskFactory.ContinueWhenAll is used to execute a subsequent Task when a group of required precedent Tasks are all completed. The set of precedent Tasks may be computed dynamically, and there may be none: in such a situation, TaskFactory should immediately start the subsequent Task rather than throw.

                    Compare with e.g. Enumerable.All: this returns true when passed an empty sequence.

                    In both cases, having no requirements isn't necessarily exceptional, and in both cases there's a clearly sensible behavior that could occur, so no Exception should be thrown.

                    • Have all collections implement generic collection interfaces

                      Many collections in the .NET framework that are not meant for general purpose usage (NameValueCollection, PropertyDescriptorCollection, ControlCollection, etc) do not implement a generic collection interface. So, in order to use LINQ to objects on a, for example ControlCollection, we must first apply the OfType<T>() or Cast<T>() operators, which wouldn't be required if this collection implemented IEnumerable<Control> or ICollection<Control>.

                      • Provide a GC that can cope with very large heaps

                        Provide a GC that can cope with very large heaps with lots of live objects while keeping a service responsive.

                        Now that we can reasonably have a server with 1TB of RAM, we should be able to cope with something like 700GB of LIVE objects in a single .NET process without the GC stopping the process for more than a faction of a second when doing a collection.

                        I don’t like having to use MemCache etc, just because the .net GC is not good at coping with large heaps. Can we have something like the Pauseless GC from Azul Systems?…

                        • Provide a customizable stream buffer size for WCF services that return Streams.

                          By default (without any ability to change the value) WCF services that implement a Stream response type cannot change the output buffer size from 16K (or 32K). Would like the ability to change this buffer size to a reasonably low value to support smaller byte arrays.

                            • 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 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.

                                      • 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.)

                                        In case this is a concern, please note that this would…

                                        • 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.
