Hello Mark and others,

thank you for the clarification. Very interesting, I hadn't though of  
these two distinct use cases, i.e. :
-on the one hand embedding Python scripting in .NET applications
-on the other hand calling .NET assemblies from applications that  
otherwise run outside of the .NET scope.

My background with .NET is more into monolytic business applications  
that don't have embedded scripting. It might be worthwhile to upgrade  
the "Python for .NET" website and clarify these different use cases.

Both technologies now seem to have a clear use case and rationale.

good evening.
Emmanuel
