Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
SearchClient.Instance.Conventions.UnifiedSearchRegistry.ForInstanceOf<PageData>()
When I inspect the LoaderExceptions property I in the current case see that it can't find Microsoft.IdentityModel.Clients.ActiveDirectory 2.21.
In another project I had the same issue with a version of Microsoft.AspNet.WebApi.Cors and I have a couple of reports from workmates also running into the same error with different references.
Are we doing something run with nuget or is there something in Epis libraries that needs to be more forgiving?
