I have created a new SQL Database on Azure, and have copied the connection string directly from the Azure Portal.

On my .NET application, when I am trying to run 'Update-Database' command in Package Manager Console to commit the migration, I receive the following error:

Error Number:18456,State:1,Class:14
Login failed for user 'benhayward'.

I can confirm that the log-in credentials are correct as I can log into the server explorer on Visual Studio using the same credentials.

My connection string:

"ApplicationDbContextConnection": ",1433;Initial Catalog=SEPMDatabase;Persist Security Info=False;TRUSTED_CONNECTION = TRUE;User ID=benhayward;Password={XXXXXXX};MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"

Extra Information:

  • I have changed my database admin password.
  • I have confirmed that the log-in credentials are correct.
  • I am on the Azure free trial.

Any advice or assistance on this would be greatly appreciated.

    Trusted_Connection and the user id/password are mutually exclusive. When you set the Trusted_Connection=True, the application is sending the security principal your .Net application is running on.

    When you set Trusted_Connection=True, you do not need to provide the User Id and Password parameter/values.
