Enable EF Migrations for Multiple Contexts: .NET Database Separation Made Easy

If you're working on a .NET project that requires multiple database contexts, you may find yourself struggling to enable EF migrations. Fortunately, with a few simple steps, you can make database separation easy and enable EF migrations for multiple contexts.

Step 1: Create a Migration Configuration File

The first step is to create a migration configuration file for each context. This file will contain the necessary configuration settings for EF migrations. You can create this file by running the following command in the Package Manager Console:

Add-Migration InitialCreate -Context ContextName -ProjectName ProjectName

Replace "ContextName" with the name of your context and "ProjectName" with the name of your project.

Step 2: Configure the Database Connection String

Next, you'll need to configure the database connection string for each context. You can do this by adding the following code to the constructor of each context:

public ContextName() 
{ 
    Database.Connection.ConnectionString = "connection string"; 
}

Replace "ContextName" with the name of your context and "connection string" with the connection string for your database.

Step 3: Enable Migrations for Each Context

Finally, you need to enable migrations for each context by running the following command in the Package Manager Console:

Enable-Migrations -ContextTypeName ContextName -ProjectName ProjectName

Replace "ContextName" with the name of your context and "ProjectName" with the name of your project.

With these simple steps, you can easily enable EF migrations for multiple contexts in your .NET project. This will make it easier to separate your databases and keep your code organized.
