I am thinking about a math equations like: c^2 = a^2 + b^2 I would like to have a function that could process any formula, and give me the individual variable formulas.

I have a windows service with a timer. Its very hard to debug it. Because I start the service and put break points in different parts of the code. When I attach the process, I expect the service to start from the very beginning instead of some randome place in the middle code where I have break points. Its hard to debug like a normal app...

Objects that derive from HashAlgorithm such as MD5CryptoServiceProvider have a Dispose() method, but it's private. Instead it has a Clear() method which "Releases all resources" used by it. WTF? Is this how to correctly dispose of a HashAlgorithm then? var hasher = new MD5CryptoServiceProvider(); byte[] hashCode = hasher.ComputeHash(...
