How to do AutoMigration in Entityframework core without using command (Using Programming only)

I use EF core in My project and I want migrate my context using Programming (not command) So I use these two concpets one by one

1.

using (var serviceScope = app.ApplicationServices.GetRequiredService<IServiceScopeFactory>().CreateScope())

{
     
    var context = serviceScope.ServiceProvider.GetService<UserInformationContext>();
     
    context.Database.Migrate();

}

2.

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, UserInformationContext userContext)

{
   userContext.Database.Migrate();

}

Problem Is ,using this two concepts can not create any Migration Folder like add-migration command Is there any way to Create Migration Folder and Migrate Context using Programming ??

Hi, @JaySoni1910-8246

From the official document of EF, we can see

EF Core will include most of the features of EF 6 gradually. However, there are some features of EF 6 which are not supported in EF Core 2.0 such as:

EDMX/ Graphical Visualization of Model
Entity Data Model Wizard (for DB-First approach)
ObjectContext API
Querying using Entity SQL.
Automated Migration
Inheritance: Table per type (TPT)
Inheritance: Table per concrete class (TPC)
Many-to-Many without join entity
Entity Splitting
Spatial Data
Lazy loading of related data
Stored procedure mapping with DbContext for CUD operation
Seed data
Automatic migration

userContext.Database.Migrate(); will update the database based on the migrations you have created. So you need to add migrations at first.
