The adapter uses the .NET unmanaged COM API to instantiate the .NET Common Language Runtime (CLR). The .NET CLR is not an emulated environment, but communication with the instance is governed by the adapter. There are several languages that can generate Microsoft Intermediate Language (MSIL) code. The adapter has been extensively tested with C# and on a more limited basis with source from Visual Basic and F#. For adapter usage requirements with any other language, contact your customer support representative.
