CoInitialize (ole32)
.
C# Signature:
[DllImport("ole32.dll")]
static extern int CoInitialize(IntPtr pvReserved);
User-Defined Types:
None.
Notes:
Besides the fact that CoInitializeEx has replaced CoInitialize, you shouldn't need to call this in managed code via PInvoke because the CLR already initializes COM when appropriate.

CoInitializeEx initializes the COM library for use by the calling thread, sets the thread's concurrency model, and creates a new apartment for the thread if one is required. Values for the dwCoInit parameter are taken from the COINIT enumeration. However, since pinvoke is a dotNET construct you should be aware that dotNET already does a COM initialization and therefore calling a CoInitializeEx function most likely will not do what you expect. This problem occurs when trying to instantiate a COM object from within dotNET where the COM objects threading model is different from dotNETs. Search on Common Language Runtime or CLR and COINIT_APARTMENTTHREADED to find posts on this issue.
