Description
Fixes #5093
This PR simulates launch profile loading for the testing host. It does not mutate the process' environment since that could cause issues with concurrently running tests. Instead, it propagates the environment variables specified in the AppHost's launch profile to the AppHost's configuration.
This PR sets the
DOTNET_LAUNCH_PROFILE
environment variable to the name of the first launch profile if not overridden. It does not consider theDOTNET_LAUNCH_PROFILE
from the test runner's environment.Checklist
