 # RhinoCommon Unit Testing
 
 ## Intro
-Example of unit testing RhinoCommon from within the Visual Studio test runner on windows.
+Examples of unit testing RhinoCommon and Grasshopper3d.
 
 ## Prerequisites

 ## Test Framework
-This project provides examples for XUnit and MS Test,
-but the principles would be easily transferable to other frameworks if needs.
+This project provides three example projects.
+   - One using the MsTest Framework `RhinoPlugin.Tests`
+   - A second one using Xunit `RhinoPlugin.Tests.Xunit`
+   - And a thrid one using the old .csproj format without PackageReference Migration where Grasshopper3d libraries are loaded directly by Rhino.Inside `RhinoPlugin.Tests.GHAutoLoad`
+
+but the principles would be easily transferable to other frameworks if needed.
 
 ## How to Run
 - Build the solution
 - Test should appear in Visual Studio Test Explorer
 - Set test enviroment to x64  
   `Test > Test Settings > Default Processor Architecture > x64`
-- Click `Run All` to run the tests
+- Click `Run All` to run the tests.
+- Some times you may need to run each project individualy as the testhost tends to get stuck.
 
 ## Further Reading
-For more info on using Rhino in a headless environment see the Rhino Compute project:
-https://github.com/mcneel/compute.rhino3d
+For more info on using Rhino in a headless environment or inside other applications please see the projects below:
+- https://github.com/mcneel/compute.rhino3d
+- https://github.com/mcneel/rhino.inside
+
+
+## Known issues
+Using the new *.csproj* format, the headless version of Rhino fails to load the GH libraries. To tackle this we are loading the library manually to the test context by resolving the specific assembly.
+
+If you are using the old .csproj format and with a packages.config for the references then GH is loading automatically.
 
 ## Troubleshooting
 - Note that when Rhino is in headless mode there is no document defined. 
 The static property `RhinoDoc.ActiveDoc` will thus be null which may trip up your plugin code.
 
-- If you have any problems getting this to work or you have a more complex use case, 
-then please get in touch via the issue tracker.
