Last time I wrote about my efforts to create minidumps with PostSharp aspects. I showed some ways of achieving that, but the main conclusion was that no out-of-the-box aspect in PostSharp provides a transformation that would allow inserting minidump generation code in the optimal place: just before throw instructions. Fortunately, it isn’t too hard to create such an aspect, even though the required PostSharp SDK is unsupported and undocumented.

Let’s start by analyzing how PostSharp aspects are architected. Then we’ll move to implementing the actual IL transformation required to temporarily store the exception about be thrown, pass it to the aspect code, and then actually throw it expected.
