SYMPTOMS

Consider the following scenario:
  • A 64-bit application that is created by using the Microsoft .NET Framework 2.0 calls some COM APIs.
  • The COM APIs have multiple instances of the same method.
  • The method uses the lcid attribute.
  • You use one of the following to call the COM APIs:
    • The managed COM interop
    • Platform Invoke (P/Invoke) code
In this scenario, incorrect methods are called.

For example, consider the following scenario:
  • You have a 64-bit application that uses a 64-bit version of common language runtime (CLR).
  • The application has two managed P/Invoke functions that have the same signature. The signature points to a single native method.
  • The two P/Invoke functions rely on the LCIDConversionAttribute class for localization support.
  • You run the application.
In this scenario, you may receive an error message that resembles the following:
System.Runtime.InteropServices.COMException (0x800706F4): A null reference pointer was passed to the stub. (Exception from HRESULT: 0x800706F4)
