___ ___ erkimt permission to create database denied by the database 'master' ______ qstntxt ___

I'm trying to migrate the database created automatically by Identity to control user authentication and this error appears:

%pre%

My connection string looks like this:

%pre%

With this same user (sa - who is the owner of the master database) and password I can create database normally through Management Studio, however when I try to create it through the migration of Visual Studio it gives this error. The user and password are correct, the user "sa" is allowed to everything in SQL Server. What can it be?

I was able to create. The error was in my connection string, in the Secutity User parameter. I changed it this way and it worked:

%pre%
