How to use ef6.exe

Question

I'm a newbie in entity framework. I have seen examples of using migrate.exe or enable-migration etc.

But migrate.exe does not exist any more. I explored the web and found that ef6.exe replaced the old migrate.exe

so I tried

ef6 -contexttypename musicstoredatacontext
ef6 -context musicstoredatacontext

nothing worked

I cannot find further support/documentation regarding the migration commands. and i'm new to migration.

Can somebody give me some hint how to work on it?

"If you execute Update-Database -Verbose inside Visual Studio's Package Manager Console, it will show you the call it uses to ef.exe to apply migrations." -Brice Lambson

It will be something like:

\ef6.exe database update --connection-string "" --connection-provider System.Data.SqlClient --verbose --no-color --prefix-output --assembly  --project-dir  --language C# --data-dir  --root-namespace  --config

Some of the arguments above can be omitted.

You can use the same strategy to determine how to create a migration (Add-Migration) with ef6.exe.
