Comparison between Stateless (on google code) and Windows Workflow

I'm starting to think that I should ditch Windows WF in favor of something simpler. I don't necessarily need to pause workflow execution for extended periods of time and restore them later.

Validation Framework in .NET that can do edits between fields

From my experience many validation frameworks in .NET allow you to validate a single field at a time for doing things like ensuring a field is a postal code or email address for instance. I usually call these within-field edits. In my project we often have to do between-field-edits though. For instance, if you have a class like this: ...

How can I wrap a COM object in a native .NET class?

I'm using an extensive existing COM API (could be Outlook, but it's not) in .NET (C#). I've done this by adding a "COM Reference" in Visual Studio so all the "magic" is done behind the scenes (i.e., I don't have to manually run tlbimp). While the COM API can now be "easily" used from .NET, it is not very .NET friendly. For example, th...

Getting information about a member invoked using Type.InvokeMember()
