+The easiest way to build the Framework+Tests is by building all tests - "<REPO_ROOT>\build_test[.bat|.sh]"

+Sometimes there is a need (after initial build) to rebuild Framework+Tests. For example when modifying the Framework to add a new scenario or when investigating a failure.
+In such case it is possible to go directly into the the Framework directory and build manually- Ex: "dotnet build -c:debug".
