This call has nothing to do with static web content and should not have ever been called with the web content path: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/?view=aspnetcore-3.1&tabs=windows#content-root Since this call is removed, the ContentRoot property is also removed from ApplicationHost as it is no longer needed. Finally, move validation of the static content path to the DashboardService where it is actually used.
