Roslyn project is The ".NET Compiler Platform"

Existing .NET compilers are replaced with new ones

• csc for C#
• vbc for VB.NET

As this an open source, the compilers are now white boxes, there are many benefits for the developer's community:

• We can obtain information about a program
• We can modify a program syntactically / semantically
• We can impact the compilation process
• We can change the compiler itself!

Infinite possibilities:

• better tools — refactoring, analysis, …
• better enforcement of coding standards
• add scripting support to your app
• target new platforms
• language research
• compiler research
