Compiler Error C3238

'type' : a type with this name has already been forwarded to assembly 'assembly'

Remarks

A type was defined in a client application that is also defined, via type forwarding syntax, in a referenced assembly. Both types cannot be defined in the scope of the application.

See Type Forwarding (C++/CLI) for more information.

Examples

The following example creates an assembly that contains a type that was forwarded from another assembly.

// C3238.cpp
// compile with: /clr /LD
public ref class R {};

The following example creates an assembly that used to contain the type definition, but not only contains type forwarding syntax.

// C3238_b.cpp
// compile with: /clr /LD
#using "C3238.dll"
[ assembly:TypeForwardedTo(R::typeid) ];

The following example generates C3238.

// C3238_c.cpp
// compile with: /clr /c
// C3238 expected
// Delete the following line to resolve.
#using "C3238_b.dll"
public ref class R {};
