upgrading to mono.addins 0.6 and 0.6.2

[Matteo Tesser]

Hello mono-addins team!,
I tried to update the Addins system of the software I'm developing.  After updating to mono.Addins 0.6 and 0.6.2  I noticed that, in Windows, the addins engine fails to scan assemblies under Windows and generates errors like the following:

Scanning file: ...\...\mydll.dll
Using assembly reflector: Mono.Addins.CecilReflector.Reflector
Error:There was an error while scanning assembly: ...\...\mydll.dll
ExceptionSystem.TypeInitializationException: The type initializer for 'Mono.Cecil.Metadata.TableHeap' threw an exception. ---> System.ArgumentException: Value does not fall within the expected range.

I saw that the cecil library have been updated  into Mono.Addins on the February 23, 2011 and this cecil error manifested to others using cecil 0.9.4: see

http://groups.google.com/group/mono-cecil/browse_thread/thread/952387ac994e47cf?pli=1


I noticed that the problem does not manifest  if I recompile mono addins using the latest stable cecil library 0.9.5.

My intention is only to share this information, hoping it's usefulness.

Best,
Matteo
