Cannot be used across assembly boundaries because it has a generic type parameters that is an embedded interop type

I am facing this error on changing a Sub to a Function in VB.Net

Type System.Collection.Generic.List(Of mshtml.IHTMLDocument2) cannot be used across assembly boundaries because it has a generic type parameters that is an embedded interop type.

Does anyone knows how to get it resolved?

I fixed this by making sure that all assemblies had "Embed Interop Types" to FALSE.

It seems that usually when you use a COM library that parameter is set to true by default.

Changing the return type from List(Of mshtml.IHTMLDocument2) to IList(Of mshtml.IHTMLDocument2) or IEnumerable(Of mshtml.IHTMLDocument2) resolves the issue.
