Why I want to do...

The problem is that all the values in the db were encrypted by .NET code that uses the ANSI x923 padding scheme.

Hi, I currently need to provide a means of adding extensibility in my application. I'm currently looking at MEF and MAF. MEF provides a simpler programming model, and also fits our usage scenarios better as we only want to load addins into a single AppDomain - this is due to the way the system has been architected. The same thing can...

What is the safest (and shortest) way do lock read/write access to static members in a multithreaded environment in C#? Is it possible to do the threadsafe locking & unlocking on class level (so I don't keep repeating lock/unlock code every time static member access is needed)? Edit: Sample code would be great :) Edit: Should I use t...

("Ok", "MovedPermanently", etc.) Is the number buried in a property somewhere in the response object? Any ideas other than cr...
