Script# lets you leverage the productivity of C# (intellisense, build-time error checking, natural language syntax), and the power Visual Studio IDE and standard .NET tools (such as msbuild, refactoring, unit testing, static analysis, code visualization, fxcop). Script# brings all this to you without abstracting the runtime environment - you're still authoring script, just with a different set of tools.
You can even use Script# to work against other existing frameworks and APIs such as jQuery, jQuery plugins and Knockout, and can be extended to work against other existing script.
