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


i facing error c# (wpf). link has not been useful

cannot used across assembly boundaries because has generic type parameters embedded interop type

just explain structure of program can tell that:

i using library made external company. can call pcdlrn

in solution have project made me incluse types in previous lib. in library define:

public observablecollection<pcdlrn.dimensioncmd> obcpcdlrndimensioncommands = new observablecollection<pcdlrn.dimensioncmd>();

in order used in main program. in short:

pcdlrn->mylib obcpcdlrndimensioncommands --> program mypcd.obcpcdlrndimensioncommands

in program want access aforementioned observablecollection doesn't build giving error in title.

--edit--- suggested have changed embedded = true false changing prop in picture error remains

as wasgooddone remarked, need use same class both (all) assemblies use generics.

in other words, if have assembly1, references interopassembly, , assembly2, references same interopassembly, , switch embedded interop type true, have two copies of types interopassembly.

if want use cross-references assembly1 assembly2, .net can't resolve it, because point of view, classes different.

when switch embedded option off, assembly reference other assembly contains interop types. , in way can use interop types in different libraries.

so, if have problem described above, means have @ least 2 assemblies referencing pcdlrn, , must switch off embedded interop type in of them.
