Troubleshooting visualizer installation

1. In order for the visualizer to work, the files need to be unblocked. This is usually available through the Explorer UI, by right-clicking on the file and selecting Properties:

   

   and checking the Unblock checkbox.

   

   Note that for a ZIP file, it's usually enough to unblock the ZIP file; there's no need to unblock the inner files.

2. Under VS 2019, you can use the visualizer with projects that target frameworks other than .NET Framework, by placing an additional copy of the DLLs in a subfolder of the main visualizer folder:

   • VisualStudioInstallPath \Common7\Packages\Debugger\Visualizers\ framework
   • My Documents\ VisualStudioVersion \Visualizers\ framework

   where framework is one of the following:

   • for a project targting a .NET Standard compatible framework, use netstandard2.0
   • for a .NET Core project, use netcoreapp
   • for a .NET Framework project, use net2.0

   (Reference)

   The ZIP file from the releases page internally follows this folder structure.
