LastFmLib.net lets you access all Web services provided by Last.fm. This also includes an implementation of the Audioscrobbler 1.2.1 submissions protocol and radio api. Also, LastFmLib.net provides a set of useful classes, e.g for caching requests and pictures and for accessing simple request easily via the LastFmClient class. The library should be fully Mono compatible (the test with MoMa was positive).
StyxLib is a .NET implementation of the Styx (9P2000) protocol for distributed systems. This protocol is used by Inferno and Plan9 OSes. It is similar to other network file systems like NFS and CIFS, but in 9P systems, files do not always represent real files on disk, but can instead be interfaces to physical devices or programs.
System# is a .NET library intended for the description of real-time embedded systems. It comes with a built-in simulator kernel and a code transformation engine that converts a design into synthesizable VHDL. The main focus is currently the development of FPGA designs. System# not only supports register-transfer-level (RTL) descriptions whose translation to VHDL is straightforward, but is also capable of converting clocked threads with wait statements to a synthesizable VHDL state machine. Furthermore, System# introduces synthesizable transaction-level modeling features. From a technological point of view, it uses reflection and assembly code (CIL) decompilation to reconstruct an abstract syntax tree (AST) from the system design. The AST conforms to SysDOM, a document object model for describing component-based reactive systems. An unparsing stage converts the AST to VHDL. The decompilation process can be instrumented in various ways by attribute-based programming. Furthermore, transformations of the AST itself are possible. This enables implementation of advanced features such as converting clocked threads to finite state machines.
