<\/span><\/h3>\nNow, navigate to your project in the Solution Explorer, right-click and select “Add > New Item…”. Choose “ADO.NET Entity Data Model” and give it a name. This creates a new model file with a .edmx extension. Once it’s created, right-click it in the Solution Explorer and select “Add Code Generation Item…”. Choose “EF 6.x EntityObject Generator” and give it a name. This creates a new T4 template file with a .tt extension. Open this file and add the following code at the top:<\/p>\n
\n<#@ template language=\"C#\" hostspecific=\"True\" #>\n<#@ output extension=\".cs\" #>\n<#@ parameter name=\"ContextNamespace\" type=\"System.String\" #>\n<#@ parameter name=\"ContextName\" type=\"System.String\" #>\n<#@ parameter name=\"ModelNamespace\" type=\"System.String\" #>\n<\/code>\n<\/pre>\nThis code sets up the T4 template to generate Entity Framework code for your model and context.<\/p>\n
<\/span>Step 3: Enable Migrations<\/span><\/h3>\nNow that you have set up your project for migrations, enable them by opening the Package Manager Console (View > Other Windows > Package Manager Console) and running the following command:<\/p>\n
\nEnable-Migrations -ProjectName [YourProjectName] -StartUpProjectName [YourProjectName]<\/code>\n<\/pre>\nReplace [YourProjectName] with the name of your project. This command creates a Configuration.cs file in your project for managing migrations.<\/p>\n
<\/span>Creating and Running a Migration<\/span><\/h2>\nNow that you’ve successfully set up your project for migrations, let’s create and run one!<\/p>\n
<\/span>Step 1: Add a New Migration<\/span><\/h3>\nTo create a new migration, open the Package Manager Console and run the following command:<\/p>\n
Add-Migration [MigrationName] -ProjectName [YourProjectName] -StartUpProjectName [YourProjectName]<\/code><\/pre>\nReplace [MigrationName] with a descriptive name for your migration. This command creates a new migration file in your project containing the changes to your database schema.<\/p>\n
<\/span>Step 2: Modify the Migration<\/span><\/h3>\nThe migration file has a series of instructions that describe changes to your database schema. Add or remove instructions as you see fit.<\/p>\n
<\/span>Step 3: Update the Database<\/span><\/h3>\nTo update the database with the changes from your migration, open the Package Manager Console and run the following command:<\/p>\n
Update-Database -ProjectName [YourProjectName] -StartUpProjectName [YourProjectName]<\/code><\/pre>\nThis applies the changes from your migration to the database.<\/p>\n
<\/span>Step 4: View the Migration History<\/span><\/h3>\nYou can view the migration history by opening the Configuration.cs file in your project, which displays all the applied migrations.<\/p>\n
<\/span>Final Thoughts<\/span><\/h2>\nMigrations keep your database schema and code in sync, and with Entity Framework Migrations in Visual Studio, running them couldn’t be easier! Follow these steps to set up and use migrations in your development workflow with ease.<\/p>\n","protected":false},"excerpt":{"rendered":"
