Access "Embed Interop Types" property of a project reference programatically

Question

I am writing a plugin for Visual Studio, I am able to see all the properties of all the references for a project, except for one property.

How can I access the "Embed Interop Types" property of a reference programmatically?

Right now I am using the VSLangProj80.Reference3 class to get the properties, but it does not include the "Embed Interop Types" property.

I have found a reference to a Microsoft internal use enumeration, VsProjReferencePropId100.DISPID_Reference_EmbedInteropTypes, but don't know how to use it to find the information I am looking for.

Answer 1

Yes, cannot work. VSLangProj80 dates from VS2005, the property was added in VS2010. There is a VSLangProj100 but it contains nothing but three enumeration types. The VsProjReferencePropId100 enum indeed defines DISPID_Reference_EmbedInteropTypes. It is the kind of identifier you'd use in late-bound COM.

I'm not up to speed on this, but I'm guessing that you might get something out of ProjectItem.Properties.

Answer 2

I'm having the same problem. Did you figure out how to get to this property?
