cosetproxyblanket (ole32)
The CoSetProxyBlanket API is not safe for use from managed code directly, you must use the .NET marshalling APIs to access the right COM functions.

C# Signature:

static extern int CoSetProxyBlanket([MarshalAs(UnmanagedType.IUnknown)]
   object pProxy, uint dwAuthnSvc, uint dwAuthzSvc,
   [MarshalAs(UnmanagedType.LPWStr)] string pServerPrincName, uint dwAuthnLevel,
   uint dwImpLevel, IntPtr pAuthInfo, uint dwCapabilities);

User-Defined Types:



Please look at, which shows how to call CoSetProxyBlanket in C#. As this is published on the MS Patterns and Practices web site I would assume this would be OK and is safe. This reference has code and discusses the issues about transition from .net object to COM IUnknown reference using the Marshal functions.
