     Setting unloadDelay=INFINITE uses the system default delay (10 minutes).

     Setting unloadDelay=0 forces the unloading of any DLLs without any delay.

Setting the delay too short (or zero) can have unintended consequences, as some DLL's will return control before they have finished cleaning up resources, or they will continue executing in the background.

Please look at http://msdn2.microsoft.com/en-us/library/aa302389.aspx#secnetch09_callingservicedcompaspnet, which shows how to call CoSetProxyBlanket in C#. As this is published on the MS Patterns and Practices web site I would assume this would be OK and is safe. This reference has code and discusses the issues about transition from .net object to COM IUnknown reference using the Marshal functions.

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.
