Exceptions out of Fault/Finally
 Assumption: This write-up assumes that you are familiar with the managed exception handling constructs (e.g. catch, filter, fault, finally). If not, you may want to read this and also refer to the CLI specification. Managed exception handling exposes constructs to handle an exception (e.g. catch and filter blocks) and also to perfor

Preview of Code Contract Tools Now Available
We’ve mentioned Code Contracts over on the BCL Blog a few times now, but never yet on the CLR Blog.  Basically, Code Contracts are a way to add preconditions, post-conditions, and object invariants to your code.  The goal is to help you catch developer errors earlier in the cycle.  In my Introduction to Code Contracts post

Why catch(Exception)/empty catch is bad
  You’ve seen the advice before—it’s not a good programming practice to catch System.Exception. Because managed exceptions are hierarchical, catching the top of the hierarchy—e.g., catch(Exception)—is an easy way to make sure that you catch all exceptions.  But do you really want to catch all except

Catch, Rethrow and Filters – Why you should care?
 A very common pattern in the usage of managed exception handling is that of catching an exception, inspecting it's type and rethrowing it once you realize it was not the exception you wanted to handle. Below is such an example (and should be avoided in preference to another approach described further below in the writeup) that uses Custo
