In Visual Basic .NET 2003, you receive the following error message:
COM Interop registration failed. Error loading type library/DLL.
In Visual Basic 2005, you receive the following error messagess:
COM Interop registration failed. Could not find a type library for assembly 'Microsoft.VisualBasic'.
error MSB3211:The assembly 'Microsoft.VisualBasic, Version=188.8.131.52, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not registered for COM Interop. Please register it with regasm.exe /tlb.
