Entity Framework Scaffold-DbContext Login failed for user

16

I am trying to build an API using Visual Studio 2017 and .NET Core 2 with Entity Framework Core. I am following the directions from This Link. I am on the section titled: Reverse engineer your model

The command they give to run is as follows:

Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=Blogging;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

My database is an Azure SQL database so I am trying to run this command using the connection string provided from the Azure portal:

Scaffold-DbContext "Server=tcp:dbname.database.windows.net,1433;Initial Catalog=DBNAME_DB;Persist Security Info=False;User ID=username;Password=password;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

I am getting returned a

From this same machine and username and password I am able to login to the database using SSMS. Does anyone have any suggestions why I am unable to run this command from Visual Studio?

I figured out my problem. My password contained the character $ and this needs to be escaped out by using ` before the $.

Did you tried to update your web.config file for connection string. This might be a reason which doesn't allow you to login to azure.

Please make sure the user login exists on the target SQL Azure database and not only on the Azure SQL Database server.

-- On master database CREATE LOGIN MaryLogin WITH PASSWORD = '';

-- On the user database

CREATE USER MaryUser FROM LOGIN MaryLogin;

Create a firewall rule on Azure portal to allow access to the Azure SQL Database as explained here. Make sure port TCP 1433 is open from your computer.
