CreateDebuggingInterfaceFromVersion Function

Creates an ICorDebug object based on the specified version information.

This function is obsolete in the .NET Framework 4. Instead, to get an interface for the common language runtime (CLR) 2.0, use the ICLRRuntimeInfo::GetInterface method and specify the class identifier CLSID_CLRDebuggingLegacy and the interface identifier IID_ICorDebug. To get an interface for CLR 4 or later, call the CLRCreateInstance function and specify the class identifier CLSID_CLRDebugging and the interface identifier IID_ICLRDebugging.
