I created a small EG Addin using VS2005 (I only have VS2002 and VS2005). Using MSBee, I successfully compiled the project inside or outside VS2005 to target .net 1.1 (thanks to your link posted here in the forum). However,
after adding the Addin from EG Add-in manager (no errors)and try to use it on the data, it gave an error saying reflection target invocation error.
I noticed that, unlike other tasks, there is no icon before my task, althought I did put an icon file in the same folder where my .net 1.1 assembly resides.
