How can I add a same table name but different schema in EntityFramework?

0

I have a situation where I need to create a new table in a separate schema through EntityFramework that has the same table name in a different schema.

How can this be done through EntityFramework? I am currently locked to EntityFramework 5.0.4, so I cannot move on to EntityFramework 6.

Existing table:

CREATE TABLE dbo.TableA ( /*table contents*/ );

New table:

CREATE TABLE AnotherSchema.TableA ( /*table contents*/ );

I believe I have already created the POCO classes correctly, and MigrationBuilder's Up() and Down() methods explicitly use the schema names:

protected override void Up(MigrationBuilder migrationBuilder)
{
    migrationBuilder.EnsureSchema(name: "AnotherSchema");
    migrationBuilder.CreateTable(schema: "AnotherSchema", name: "TableA", ...);
    // ...
}

protected override void Down(MigrationBuilder migrationBuilder)
{
    migrationBuilder.DropTable(schema: "AnotherSchema", name: "TableA");
}

However, when I execute Update-Database I get the following error:

Build succeeded.
