  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.

    • better support loading multiple versions of the same assembly

      In my production environment, our servers currently load 645 assemblies many times containing multiple versions of the same assembly. For the most part, our custom assembly resolver seems to work when we hook up to the resolver event. However, we recently migrated over to storing our assemblies in Subversion under a flat folder structure by version number to help manage our deployments. This exposed a new problem with the .NET Framework assembly resolver because if the filename of the assembly in Visual Studio reference includes the version number, the file on disk can no longer be resolved without also changing…

      • Add non-generic base class to TaskCompletionSource<T>

        The TaskCompletionSource<T> class should have a non-generic base class that would implement the methods that are currently in TaskCompletionSource<T> and which don't operate on the result type.

        Specifically these are: SetCanceled, SetException, TrySetCanceled, and TrySetException.

        This would allow for canceling/failing a diverse collection of TaskCompletionSource objects without needing to know what the result type should have been.

        • 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.

              • 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.

                        Provide an Entity Framework Factory similar to the ADO.Net Provider which allows easy swapping between different Entity Framework models such as SQL Server, Oracle, MySQL, DB2 etc. simply by providing the appropriate database provider information in a manner similar to the current ADO.Net Database Provider Factory.

                        • 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)

                              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.

                              • .Net Framework: SSL/TLS and Certificate Pinning

                                The Diginotar failure demonstrated what a spectacular PKI failure looks like. One of the lessons learned was that Google's Chrome did not suffer the Man-in-the-Middle (MitM) attacks.

                                Chrome did not suffer from PKI's failure because it pinned its certificates. As such, a phony certificate to mail.gmail.com (?) was rejected by the browser.

                                The .Net Framework added SSL/TLS classes in .NET Framework version 2.0. However, there is no easy way to pin a certifcate - currently one must use ServicePointManager.ServerCertificateValidationCallback.

                                It would be awesome if the SSL/TLS classes would offer a Pinned property. I imagine the property to take a thumbprint…

                                  • 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.)

                                      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.

                                        • Add smooth streaming media element to WPF

                                          Currently you can play smooth streaming media from silverlight and winrt, but not from a desktop application! (Or windows media player for that matter)
