Run “dotnet tool restore” to make the “dotnet-ef” command available.

To make the “dotnet-ef” command available, you need to run the “dotnet tool restore” command. This command is used to restore the dotnet tools necessary for your project.

First, open your terminal or command prompt and navigate to the directory where your project is located.

Then, run the following command:

dotnet tool restore

This command will fetch and install the necessary dotnet tools specified in your project file (usually the .csproj file).

Once the tool restore process is complete, you should be able to use the “dotnet-ef” command in your project.

For example, if you want to scaffold a new migration using Entity Framework Core, you can now use the following command:

dotnet ef migrations add NewMigration

This will create a new migration named “NewMigration” in your project’s migrations folder, which can be used to update your database schema.
