>The Languages team has been rewriting the C# compiler in C# and the VB complier in VB. The code name is Roslyn. There were several reasons for doing this including:
>
>- Provide compiler as a service. Roslyn has hooks into the compile process that can be used for all types of things including injecting code, getting statistics, etc.
>- Some of the features they wanted to add to the compiler were very difficult in the current compiler, written in C++. This rewrite will allow those features to be added in the future
>- Fix bugs. There were a couple of bugs that were very, very rarely hit in the current compiler. If your code hit those, you will see a behavior change in the emitted code, but it is VERY unlikely that you will hit those bugs
