  1. Support for "dpi aware" bitmaps in WPF

    An article on MSDN (http://msdn.microsoft.com/en-us/library/ms701681.aspx) recommends providing bitmaps in several sizes for each graphic. This is a very good idea, and there should be built-in support for this in WPF.

    Example:

    <Image Source="myBitmap.ico" Width="16" Height="16" />

    Then, depending on the dpi setting, WPF automatically will select that bitmap in the ico file whose size matches best the required pixel size (i.e. 96 dpi -> 16x16 pixels, 120 dpi -> 20x20 pixels etc.).

    This, of course, is only an example of how it could be implemented, there might be better ways.

      • Include ObservableSet/ObservableHashSet to BCL

        In .NET 3.5 the BCL team finally introduced HashSet. But we had to wait until .NET 4.0 to get an ISet interface. For 4.5, can we please get an ObservableSet or ObservableHashSet (whatever they'd like to call it) class? (For 5.0 I'm planning to ask for a ReadOnlyObservableSet, but I'll try not to overwhelm the BCL team by requesting that too soon.)

        • Synchronous API for Silverlight under Secondary Threads

          Silverlight (and now Metro) have only asynchronous calls. This is done to avoid developers from using synchronous calls when they should not do it.
          But, what's the problem of using synchronous calls from secondary threads? It is very easy to check if the thread is the main thread (or even to put a StaticAttribute and check if it is a UI thread or anything else).

          Synchronous calls avoid unnecessary delegates and complexity and, in many cases, have better performance.

          • 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).

            • Add icon property to the FileInfo and DirectoryInfo classes

              Currently, the only ways to obtain a file or directory's icon is to use Shell API's, which are often slow and clunky, especially when processing through many files or directories. Please add the ability to expose a file or directory's icon through the FileInfo and DirectoryInfo classes. (As an extension, the ability to specify the icon size you want to obtain from a list, such as 16x16, 32x32, 64x64, etc.)

              • add a new overload method bool ConcurrentDictionary.TryRemove(K key, T val)

                Please add a new overload method
                bool ConcurrentDictionary.TryRemove(K key, T val)
                which only remove dictionary's entry if the current value equals to provided second parameter val. Right now such fuctionality can't be achieved by existing atomic methods.

                • Update WinForms Framework, by using DirectX instead of GDI+ and updating some of the controls

                  WinForms is a technology that is still being heavily used for enterprise development, since it's fast, tested, reliable, and it enhances rapid development.
                  Yet, Microsoft seems to have abandoned it in favor of WPF.
                  I think that WinForms could and should be developed side by side with WPF. Microsoft should give it a little more love and update some of its core, migrating it from GDI+ to DirectX, or even offer them as an option to the developer.

                  • Add an EmptyDataText template to the asp:Repeater

                    As with the GridView, the Repeater control would benefit from an EmptyDataText template that rendered exactly as defined, e.g.

                    <asp:Repeater ID="rpt_products" runat="server">
                    <EmptyDataTemplate>
                    <div class="nodata">No results found!</div>
                    </EmptyDataTemplate>

                    • CIL Multiply/Divide Support For 128-bit Result/Dividend

                      The NET CLR does not fully support multiplies or divides of 64-bit values. At the CPU level, a 64-bit multiply can produce a 128-bit result, and a divide can act on a 128-bit dividend. This mirrors 32-bit multiplies and divides, where the processor can return double-size (64-bit) multiply results and divide a double-size (64-bit) quantity by a 32-bit quantity. The x64 instruction set supports this via the IMUL/IDIV instructions, but there are no CIL instructions to do so. Consequently, the performance of applications requiring significant use of 128-bit integers is degraded. This also impacts the performance of cryptography and operations…

                      • Provide a Uri.Combine method that accepts a variable number of arguments

                        Provide an easy method that allows combination of strings for building Urls either in the form of a method such as Uri.Combine which accepts an array of string arguments which contain the relative Uris. This allows for easy concatenation of Uris from multiple strings rather than passing individual relative Uri arguments.

                        • Add Voice Recognition feature into .NET Framework to recognize/identify different persons’ voice

                          At present, there is no Voice Recognition feature in both System.Speech.Recognition namespace (System.Speech.dll) and Speech SDK 5.1 to recognize/identify different persons’ voice.

                          The “Voice Recognition” is a different technology from “Speech Recognition” with radically different objectives.

                          What is speech recognition?
                          Speech recognition is the process of capturing spoken words using a microphone or telephone and converting them into a digitally stored set of words.

                          What is voice recognition?
                          While speech recognition is the process of converting speech to digital data, voice recognition is aimed toward identifying the person who is speaking.

                          Many customers consult such requirements in MSDN Forum and…

                            • Source open or open source System.Net.Http.dll

                              I am probably like others thrilled about the awesome updated http://referencesource.microsoft.com/ site, which gives us great insights about a lot of .NET internals.

                              After browsing for a while I noticed that System.Net.Http.dll is also listed but all you can see are the method signatures and the XMLDoc, which is kinda disappointing.

                              Therefore I want to suggest if it's possible to source open or even open source the System.Net.Http.dll

                              • Add ForceHTTPS to ScriptManager

                                For web applications that use the Microsoft CDN (EnableCDN=true) and are behind a Hardware Load Balancer (HLB) and the SSL cert is bound only to the HLB, the ScriptManager uses the protocol of the request coming to IIS. In this scenario, IIS only sees http coming from the HLB even though the HLB sees https coming from the client. Thus the client's https request of a page results in mixed mode content because the Microsoft CDN references for asp.net are rendered as http.

                                Please add a property to ScriptManager to ForceHTTPS which would allow applications running in this configuration to…

                                • Compiler exports graph of possible exceptions for function

                                  As the compiler goes through code it should export the possible exceptions a particular function can throw. While this is somewhat like the Java feature, this can happen automatically and be displayed to downstream callers. Since all functions would have this information the graph should be fairly easy to generate for new functions.

                                  • Make JoinableTaskFactory available outside of VisualStudio

                                    Microsoft.VisualStudio.Threading.JoinableTaskFactory is in incredibly useful tool for bridging non async aware code forward into the new world of async. Without it or something like it, it can require huge amounts of change in order to migrate code forward without causing a nightmare scenario of deadlocks, hangs and poor responsiveness.

                                    • Bring the crypto namespace into the portable classes.

                                      The portable classes support WCF but today's modern apps need protocol encryption and advanced message authentication over WCF channels. The lack of crypto makes this challenging and requires targeted platform compiles.

                                      • .NET Dynamic References For Specific Builds

                                        Sometimes at our organization we need to dynamically change our references depending on what type of build we are making. As it is now Visual Studio doesn't have a means to assign conditional references in projects. (ie: If HomeEdition build reference basic security.dll. If enterprise version build reference extended security.dll)

                                        Dynamically loading .net classes using reflection isn't always the answer when some classes have to be used extensively.

                                        • Support System.Web.HttpUtility in Portable Class Library

                                          In HttpUtility, UrlEncode, UrlDecode, HtmlEncode, HtmlDecode are just process string. Why portable class library do not support it?
                                          Please support this and add more classes support in portable class library which is only depend BCL.
