The upcoming release of the .NET Framework 3.5 (which will ship with Visual Studio® 2008, formerly code-named "Orcas") includes a number of performance and functional enhancements to these core networking layers. In this article, we'll look at three key changes provided by the System.Net team:High performance Socket APIInternational Resource Identifier support for URIsPeer-to-Peer (P2P) namespaceThe upcoming release of the .NET Framework 3.5 will introduce changes to the Framework itself. The features described in this article are available in the Beta 1 release of Visual Studio 2008, available for download from MSDN®.Socket Class PerformanceIn version 2.0 of the .NET Framework, the System.Net.Sockets namespace provides a Socket class that offers virtually all the functionality of the Windows® WinSock Win32® APIs. This functionality comes in a class with methods and properties designed for developers of managed code. On Socket, there is a set of synchronous methods, including Send and Receive, with various parameter overloads for a variety of scenarios. These synchronous methods are easy to.

Of bytes possibly returned into a buffer, enabling this check will facilitate verifying that the code parsing the stream of data off of the network does so correctly, independently of the number of bytes received per call to Winsock. Issues in stream parsers have been a source of high-profile bugs, and these properties are provided to ease verification of correctness, as this is particularly difficult to test. Note: This does not change the data returned – it only slows it down at a specific rate: the application should behave exactly same fashion with this enabled or disabled.The following command line enables the fragmentation of all incoming TCP streams to all TCP IPv4 and IPv6 sockets created in myApp.exe and all binaries loaded by myApp.exe.appverif -enable Networking -for myApp.exe -with Networking.FragmentsEnabled=True Networking.FragmentSize=10!avrf Debugger Extension!avrf -net -socket count - displays open and closed socket handle count!avrf -net -socket dump [-v] [HANDLE] - displays socket handle(s), verbosely or not.!avrf -net -wsastacks - displays the current WSA init count and chronological list of stack traces for WSAStartup/WSACleanup.!avrf -net -wsastacks count - displays the current WSA init count.!avrf -net -socket count - This command will give the overall number of socket handles that are being tracked, both opened and closed. Note that these are tracked in a circular queue, so there is a ceiling to the total being tracked. Sockets are added to the opened list when one of the Winsock APIs which allocates a socket handle is called. For example, socket(), WSASocket(), accept(). Sockets are moved from the opened list to the closed list when the closesocket() function is called on that socket handle.!avrf -net -socket dump [-v] [HANDLE] - This command will enumerate the socket handles. "-socket dump" will list all tracked opened and closed socket handles by their SOCKET values. The optional -v flag will additionally print the open or close call stack immediately after printing each SOCKET value. The optional HANDLE field will list only the specified SOCKET handle and its open or close call stack.Here are example of the various -socket usage options:0:008> !avrf -net -socket countNumber of open socket handles = 16Number of closed socket handles = 12 0:008> !avrf -net -socket dumpCLOSED SOCKET HANDLE - 0x47cCLOSED SOCKET HANDLE - 0x2ccCLOSED SOCKET HANDLE - 0x8c4CLOSED SOCKET HANDLE - 0x6bcCLOSED SOCKET HANDLE - 0x44cCLOSED SOCKET HANDLE - 0x578CLOSED SOCKET HANDLE - 0x6f4CLOSED SOCKET HANDLE - 0x5b4CLOSED SOCKET HANDLE - 0x4d8CLOSED Works normally.
