PDK for .NET Limitations?

Hello all,

I am looking to find some information on any limitations when developing SAP Portal components using .NET, as well as do a comparison between developing iViews using Java and .NET.

Are there any EP components that cannot be developed using .NET, or any standard functionalities that may be accessed through Java coding but not .NET? Any documentation available on this? (other than "known bugs and limitations" section under ".NET Interoperability")

Is there any documentation available that would compare the development of iViews using Java and .NET and "can-do"/"cannot-do"?

Your help is greatly apprecaited!

Cheers,

Aniruddh
