Run ef migrations on startup in asp net core 6 application

Introduction

ASP.NET is a popular programming language used for building web applications. It provides a framework for websites, web services, and web applications. One common task in ASP.NET development is running Entity Framework (EF) migrations on application startup. In this article, we will explore how to this in an ASP.NET Core 6 application.

Setting up EF Migrations

Before we can run EF migrations on application startup, we need to set up EF migrations in our ASP.NET Core 6 application. To do this, we first need to install the necessary NuGet packages. Open the Console and run the following command:

Install-Package Microsoft..Tools

This will install the EF Core Tools package, which provides the necessary tools for running EF migrations.

Configuring EF Migrations

Once we have the EF Core Tools package, we need to configure EF migrations in our ASP.NET Core 6 application. Open the Startup.cs file and add the following code to the ConfigureServices method:

This code configures EF to use a SQL Server database with the connection string specified in the appsettings.json file.

Running EF Migrations on Startup

Now that we have set up EF migrations and configured our database context, we can run EF migrations on application startup. To do this, open the .cs file and modify the CreateHostBuilder method as follows:

This code modifies the CreateHostBuilder method to include a call to the Migrate method on the database context. This will apply any pending EF migrations on application startup.

Conclusion

In this article, we have explored how to run EF migrations on application startup in an ASP.NET Core 6 application. By following the steps outlined above, you can ensure that your database is always up to date with the latest migrations. This can be particularly useful when deploying your application to different environments or when working in a team where multiple developers may be to the database schema.
