exception: The method or operation is not implemented on database update

[szymongaertig]

Should migrations work properly on EF 1.1 ?

I use:

"SapientGuardian.EntityFrameworkCore.MySql" : "7.1.15"
"Microsoft.EntityFrameworkCore": "1.1.0",

after invoking update db command:

dotnet ef database update --context DbContextClassName

if get:

System.NotImplementedException: The method or operation is not implemented.

It could be that your migration is trying to do something that is not yet supported. Does it work for you with EF 1.0?

This library is no longer maintained. There are many alternatives which are far more complete and better tested, such as Pomelo.EntityFrameworkCore.MySql
