This version of the OPC .NET API supports .NET 2.0 and has been tested on Windows Vista. The OPC .NET API is primarily intended to provide interoperability between existing OPC specifications and applications developed in the .NET environment. The API does support COM based and SOAP/XML based servers via the same set of interfaces, however, the API does not introduce new concepts or data models. In other words, the .NET API is intended provide an intermediate step between the existing OPC technologies and the new technologies which are part of the Unified Architecture initiative.
