Is there any API in VSPackage which exposes AST for .NET languages?

Hi,

I am developing a VSPackage in C# language.

I am trying to develop a tool which refactors the code for certaiin rules specific to my needs.

I want to know if there is any API in .NET Which helps us get the AST?

If yes, can any one brief me about that API?
If no API is present, then is there any other possibility to get AST for .NET? :)


Thanks,
Nayana
