How to enable migrations in Visual Studio for Mac

I have Visual Studio for Mac and I'm trying to learn Xamarin with Azure using the following tutorial: https://adrianhall.github.io/develop-mobile-apps-with-csharp-and-azure/chapter3/server/

At some point, I have to enable EF migrations. The tutorial says: Go to View -> Other Windows -> Package Manager Console.

Unfortunately there is no Package Manager Console in Visual Studio for Mac... so how do you handle things like enable-migrations, add-migration or update-database on the Mac?

I had these errors

When i ran this command

dotnet ef migrations add nameOfMigration

The error that I got was this

No project was found. Change the current working directory or use the --project option.

Then add at the end the solution of the project that I had in the root

dotnet ef migrations add nameOfMigration --project project.sln

But it gave me another error

error MSB4057: The target "GetEFProjectMetadata" does not exist in the project.

I realized that it had to be inside the project folder and the csproj file

dotnet ef migrations add nameOfMigration --project Project/Project.csproj

And for me this was my solution

Mac Users

If you have N-Layer Architecture and multiple projects, make sure you're running command on the right path (possibly under the startup project path)

I was having issues because of a wrong path

dotnet ef database update

Of course you have to install ef first

dotnet tool install --global dotnet-ef --version {VERSION_NUMBER}

then export path

export PATH="$PATH:/Users/firatkeler/.dotnet/tools"

And do not forget to install db locally if your settings are pointing to a local db. Install and try to connect it first, then apply dotnet ef database update command.

This is not currently supported with Visual Studio for Mac out of the box.

There is a NuGet extensions addin that adds a PowerShell console to Visual Studio for Mac. This is available from the Extensions Manager, and provides a NuGet Package Manager Console window, available from the View - Other Windows menu. This allows you to run the EF PowerShell commands that you can run in Visual Studio on Windows.

If you are using Entity Framework 7 (or what they are calling Entity Framework Core) then you should be able to use the commands with the .NET Core command line.

dotnet ef migrations ...

If you are using Entity Framework 6 then you would need to find another way to call the migrations instead of using PowerShell. Entity Framework 6 has PowerShell commands that are specific to Visual Studio. They were ported to SharpDevelop but involved re-writing them to work with that IDE.
