Compiler Error C3846

'symbol' : cannot import symbol from 'assembly2': as 'symbol' has already been imported from another assembly 'assembly1'

A symbol could not be imported from a referenced assembly because it was previously imported from a referenced assembly.

Example

The following sample generates C3846:

// C3846a.cpp
// compile with: /LD /clr
public ref struct G
{
};

And then compile this:

// C3846b.cpp
// compile with: /clr
#using "c3846a.dll"
#using "c3846a.obj"   // C3846

int main()
{
}
