Csharp (Blazor) User Interface for TestStand - Early Access Release

This solution provides a modern-looking, scalable and maintainable User Interface for TestStand. A TestStand User Interface is an application that provides a graphical interface for executing tests at a production station, to monitor, debug and control execution of TestStand sequences. You can modify the source code and customize the user interface to suit your specific testing needs.

This user interface is built using Blazor framework targeting .NET 8. It uses new C# UI controls for TestStand, that no longer use ActiveX. It uses electron to host the application on a Windows desktop. For more details on TestStand user interfaces & best practices, refer here.
