I am a FoxPro programmer who will be moving into the .NET world soon and I have been researching .NET application frameworks. So far I have found MM.NET, Strataframe, DevForce, Deklarit and CSLA.NET. The prices range from free to thousands of dollars. Selecting a framework is a big commitment in time and money.

Has anybody had experience with these frameworks (or others)? What are the pros and cons of each? How should I go about evaluating them and making a final choice?

Thanks in advance.
