具有混合语言解决方案的全局名称空间

Question

I have a VB.NET project which has project references to another VB.NET project and a C# project. Each of the referenced assemblies defines a class with the same name, say Class1 . I can't in either case access it without the namespace itentifier, ie Dim c As Class1 , which would be ambiguous.

The compiler is forcing me to use

Dim c As Global.C#Namespace.Class1

but Global can be omitted for the VB.NET class

Dim c As VBNamespace.Class1

What function is the Global identifier serving in this case, and why only for the C# reference? And why is it unnecessary (actually Global.VBNamespace.Class doesn't compile) in the VB.NET case?

Answer 1

There was a legacy class with the same name as the referenced C# namespace name. The compiler recognized that identifier to be the class instead of the namespace in the referenced assembly.

The important point is that the compiler was being confused by a namespace and a class sharing the same name.
