Measurement Studio for Visual Studio provides a collection of managed .NET and MFC C++ libraries for advanced analysis, scientific user interface controls, and measurement data networking. Measurement Studio also provides code generation and integration tools with Visual Studio. Measurement Studio and NI-DAQmx ship with .NET examples. Please see this White Paper or this KnowledgeBase article for the location and other general information about the examples. It is possible to create a NI-DAQ Application without Measurement Studio.
Also, National Instruments does not provide native .NET components for Traditional NI-DAQ (Legacy). Measurement Studio support for Visual Studio 2003 and later do not provide additional functionality for developing Traditional NI-DAQ (Legacy) applications. Instead, you can use the Traditional NI-DAQ ActiveX controls to perform data acquisition. The CWDAQ ActiveX control is provided with the Traditional NI-DAQ (Legacy) Driver and does not require Measurement Studio.
