Problems with the VS SDK

It looks this will not be as easy as I expected to use F# for the Visual Studio plugin (based on IronStudio). It is not just terribly slow, but it looks like the template for creating VS studio language integration is using some parts with dependent types. Yes, I know it might be only my limitations not seeing an obvious solution to this, but it looks like the project classes the ToolsPackage class and the SolutionAdviser classes are too interdependent... I have to think how should I solve this problem.
