Download the Microsoft Code Analysis Tool .NET

Microsoft has just recently release a new tool called the "Microsoft Code Analysis Tool .NET" (CAT.NET) which helps common variants of common web application vulnerabilities. The tool does this by scanning your application, and installs as a Visual Studio snap-in (plugin). Here's information about the tool:

"The engine works by reading the target assembly and all reference assemblies used in the application -- module-by-module -- and then analyzing all of the methods contained within each. It finally displays the issues its finds in a list that you can use to jump directly to the places in your application's source code where those issues were found."
