Hello,
I made an add-in (,net 3.5 , ArcMap v.10.2) that contains a button.
From this button I try to access to a custom COM Extension class, that implements IExtension.
From other COM classes I just do the following:
var extUID = new UIDClass {Value = "<CustomExtensionName>"
return ArcMap.Application.FindExtensionByCLSID(extUID) as <CustomExtension>
and it works fine.
When I try to use this function from add-in, I get IExtension, but when I try to cast is to my custom Extension class I just get null or InvalidCastException..
Can someone help me?
