Class/property level attributes are not all copied during repack when AttributeUsageAttribute is inherited from a base type #249
Description
If a specific property of a class has multiple attributes of the same type, and the "AttributeUsageAttribute" is inherited from a base type, then the "AllowMultiple" value of the "AttributeUsageAttribute" that was inherited is not honored. Instead, only 1 attribute of that type is copied by default in ILRepack.
When ILMerge is used, the default behavior is to copy all of these Class level attributes when the inherited "AttributeUsageAttribute" that is set in a base type has "AllowMultiple" set.
Can we get ILRepack to behave more like ILMerge in how it handles class/property level attributes?

I was wrong about the /copyattr and /allowMultiple flags, these did not change the behavior on my class/property level attributes during repack. I found instead that the "AttributeUsageAttribute" is not honored in ILRepack when it is inherited from a base type. This seems to be the source of this difference in behavior from ILMerge to ILRepack.
