Guids generated with this will return the name using the FmtIdToPropStgName Function, and can be used to generate a new IPropertyStorage interface with IPropertySetStorage.Create(). The name returned will be filled to 26 chars with the letter 'a' due to the fixed size of a Guid and the fact that we're passing all zeros in the BitArray after the name finishes to reach this size.

This only appears to be an issue with VS2008, and it may have been fixed by the time you are reading this, so try to run the project first, and if you click on one of the 'TaskDialog' buttons and see it popup (ie you dont see an exception) then you do not need to take these steps, if you do get an exception, follow the steps below:

This is apparently not accurate as the P/Invoke layer automatically generates a marshaling stub at a fixed address:
