    Hi vvijaydeveloper

    To perform the database migration, you can set the *.Migrator project as the Startup Project and run it to create the database. The *.Migrator project is also used for other purposes. You can check the details here.

    Alternatively, after opening the Package Manager Console, select the *.EntityFrameworkCore project from the Default Project dropdown menu at the top. Then, set the *.Web.Mvc or *.Web.Host project as the Startup Project through the Solution Explorer. You can update the database by entering the following command in the console:

    Update-Database

    or

    Update-Database -Context {{YourProjectName}}DbContext

    Hello Team

    Same experience "More than one DbContext was found. Specify which one to use. Use the '-Context' parameter for PowerShell commands and the '--context' parameter for dotnet commands."

    • The above suggestions are already in placed.

    This error message/prompt only showed on the latest version - 13.4. Previous version 13.3 was ok.

    Please advise and help us with this.

    Hi @glenasyncXViii,

    I tried it and it is running with -Context param. I'll check it with the ANZ 13.3 version.

    Hi @pliaspzero,

    You can resolve your problem with using -Context flag as below:

    Update-Database -Context {{Your_DBContext_Name}}

    I dont get this one. Why this is not updated in the documentation. https://docs.aspnetzero.com/aspnet-core-mvc/latest/Getting-Started-Core
