Example 1: Remove table prefix:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>("");
}

Example 2: Change to another prefix:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>("MyPrefix");
}

AbpZeroDbModelBuilderExtensions class will be included to Abp.Zero nuget package in the next version (https://github.com/aspnetboilerplate/module-zero/issues/165).
Currently, you can copy in into your project.

For future reference, to implement this:

1. Add the OnModelCreating override block to your DbContext class in EntityFramework project.
2. In package manager console, add a migration e.g. "Add-Migration 'Remove_Abp_Prefixes'"
3. Update the database: "Update-Database"

This overrides any custom attributes placed on Entities [Table("AppUser")]

I add onModelCreating to my dbContext like below;

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);
    modelBuilder.ChangeAbpTablePrefix<Tenant, Role, User>("MyPrefix");
}

(Of course i changed "MyPrefix")
After that i typed "update-database" in package manager console. After i looked database tables i saw they are empty. So seed method is not working.

How can i solve this problem?

When I use this, I keep on getting this errors: "Invalid object name 'Editions." Does anyone know how to remove thew Abp prefix from all table without error. This is a brand new project. I haven't added any custom code.
