Use the .NET Adapter to call .NET assemblies written in any language compliant with .NET, such as C# or Microsoft Visual Basic .NET. TestStand installs

.NET if it is not present on your machine during installation, which allows you to take advantage of the capabilities of the .NET Adapter. You can configure the .NET Adapter using the .NET Adapter Configuration dialog box.
Note You can execute .NET Framework assemblies using .NET as long as the resources used in the .NET Framework assemblies are present in .NET.
When you specify a module for a step, the TestStand Sequence Editor displays the .NET Module tab and TestStand User Interfaces launch the Edit .NET Call dialog box.
Note  In versions of TestStand earlier than TestStand 2010, you could call code modules with the .NET Adapter even when the prototype in the assembly did not match the prototype you specified for the step. In TestStand 2010, the .NET Adapter and the TestStand Sequence Analyzer return an error when the prototype does not match exactly. However, for compatibility purposes, the .NET Adapter uses a similar algorithm as in previous versions of TestStand to try to run the code modules despite the error. National Instruments does not recommend relying on this behavior. NI recommends that you use the sequence analyzer and update the prototypes of .NET steps as needed when the prototypes in code modules change.
