After making an upgrade of site with version 7.8.2 to version 9.10.2 I get an 500 error when the site starts up. After looking in the Event Viewer I find this quite lenghty error:

When I check the database I see that the new tables for users, roles which after some version changed from aspnet_users => Users are not in the database. I have run the commandlet Update-EpiDatabase in Package Manager Console, so the database is updated (i hope!). So my thought about this is that due to the lack of these tables in the database I get this exception. The project for the site uses .Net framework 4.6.1. I also went from 7.8.2 directly to 9.10.2, is that a problem?

Someone who seen this before or maybe I should report it as a bug to Episerver?

I have found how to create these tables via the Package Manager Console with the following three steps:

1. Enable-Migrations
2. Add-Migration Init
3. Update-Database

But when I run the first one I get the following error:

No context type was found in the assembly [my assembly name]

I can set the ContextTypeName or ContextAssemblyName as a parameter for the Enable-Migrations, but what is that for Episerver?
