Is there dotPeek API available for usage in a .NET (C#) project? Does JetBrains SDK contain decompilation API?

Hi,

I need to decompile .NET dlls and analyze their syntax trees etc. The problem with other (free) software is that they have some problems with a few corner cases - dotPeek, however, decopiles it correctly.

The question is: does the SDK contain API for decompilation? If not, is the API for that available elsewhere?

If any of the above is true, does a license for ReSharper Ultimate make me eligible for the usage of such API (i.e. the SDK)?

Thanks,

Dawid
