1 TestStand 2012 will not support step into for .NET adapter with VS 2005, 2008.

2 Full support for code generation, debugging, and building custom UIs. Debugging managed code will require VS 2010 or newer. Allowed but not supported: 2005.

3 Allowed, but not supported: 2008 and earlier. VS 2008 and earlier cannot debug TestStand 2014 using managed debugging because TestStand uses .NET 4.0.TestStand will not install integrated documentation for VS 2008.

4 TestStand 2024 Q4 supports executing .NET code modules targeted to .NET 8. All .NET based user interfaces and custom step types should target .NET Framework 4.8.

 

Note: For TestStand 2012 and later, you can load earlier versions.

 

TestStand can execute code modules developed with earlier versions of Visual Studio; however, NI performs limited testing with earlier versions of Visual Studio.
