Update-Database fails creating a database with mssqllocaldb

See original GitHub issue

Dear Maintainer,

Update-Database fails creating a database with mssqllocaldb when using the default App.config I receive the following error: CREATE FILE encountered operating system error 5(Access is denied.) while attempting to open or create the physical file ‘C:\Users\[Username][Projectname].[Contextclass].mdf’.

It looks like it is missing a '\' between the username and the projectname.

Is this database location assigned by SQL Server LocalDb or is this a problem in ‘System.Data.Entity.Infrastructure.LocalDbConnectionFactory’?

Thank you in advance.

Best regards,

NiekGr

Installing and applying the latest SQL Server 2017 CU is probably the simplest cure.

Seems related to conflicting version of SQLLocalDB. Visual Studio comes with version 2016. The problem occurs when you have installed version 2017. To resolve the problem follow these steps:

Uninstall Microsoft SQL SERVER 2017 LocalDB
Open command prompt
SqllocalDB i “MSSQLLocalDB” (will probably give you an error)
SqllocalDB delete “MSSQLLocalDB”
SqllocalDB create “MSSQLLocalDB” This will recreate the instance using the correct (2016) version of SQL Server LocabDB

EntityFrameWork migraton will now succeed (slash is added to the path)
