LNK2020 error

Simon Jefferies

Hello,

I am trying to use a Managed C++ .NET (DLL) Class library within my Managed
C++ .NET forms application.

I have both projects in the same solution and have the class library under
my references branch in the forms application.

When I build i get the following linker error:-

LINK : error LNK2020: unresolved token (06000076)
MenuItems.MenuSystemPage::.ctor
LINK : error LNK2020: unresolved token (06000077)
MenuItems.MenuSystemPage::Finalize

Any ideas why this is happening?

Hi Simon,

Is it well when building your Managed C++ .NET (DLL) Class library project
alone?

If so how about using this Managed C++ .NET DLL in a .NET C#/VB.NET
project, is there any problem again?

And if that Managed C++ .NET DLL can be built OK with a non-Managed C++
project, I suggest you can take a look at the following threads:

Thanks!

Yes it is.

project, is there any problem again?
Its fine.

To explain the problem further, if I create a managed C++ .NET DLL and
reference it in my project, I get class redefinitions and if I dont I get
the Linker error 2020 (presumbly because the library functions aren't
loaded - although it only complains about the constructor/destructors).

If I create a VB .NET project it seems to handle it better and with a simple
reference it finds all the classes it requires and runs fine.

OK, Simon:

It looks similar to the problem which the google group threads(I mentioned
in my first message) discussed about, is that useful to your scenario?
Thanks!
