re: Dispose Dos and Don'ts

No sure I agree with "Don't throw exceptions in Dispose". There are certainly places in the .net framework where this happens (e.g. disposing a faulted wcf client). I also haven't been able to find anything in the official documentation warning against this.

I am running on Vista x64 SP1 with VS2008 SP1 with .net 3.5 SP1, and the following code crashes the run-time:

static int Main(string[] args)

{

byte[] hash = new byte[20];

GCHandle gch = GCHandle.Alloc(hash, GCHandleType.Pinned);

IntPtr MyPtr = gch.AddrOfPinnedObject();

GCHandle temp = GCHandle.FromIntPtr(MyPtr); //This line crashes the CLR (the exception cannot be caught!!!!).

temp.Free();

return 0;

}

The system event log says ".NET Runtime version 2.0.50727.3053 - Fatal Execution Engine Error (000007FEF95CAA6E) (80131506)"

Why is that happening?
