Suggestion: Use SQL Server security for connection strings on Linux

From @badersur on July 13, 2017 21:3

Steps to reproduce

1. dotnet new mvc -au Individual -uld true

2. dotnet restore

3. ASPNETCORE_ENVIRONMENT=Development dotnet run

4. visit http://localhost:5000/Account/Register, enter data & press register

Expected behavior

The site should register the user & work without any issue

Actual behavior

An error occurred with these messages:

An unhandled exception occurred while processing the request.

NotSupportedException: The keyword 'integrated security' is not supported on this platform.
System.Data.SqlClient.SqlConnectionString..ctor(string connectionString)
....

Solved by changing the connection string to use SQL Server Security:

"DefaultConnection": "Server=localhost;Database=aspnet-MVCAuthSQL;Trusted_Connection=False;MultipleActiveResultSets=true;User Id=SA;Password=my-secret-password;"

I suggest changing the templates to use SQL Server Security on Linux distributions, or adding another connection string (and suggesting to use it in Startup.cs) or at least link to https://msdn.microsoft.com/en-us/library/jj653752(v=vs.110).aspx#sqlserver in Startup.cs…

I spent many hours to find the solution (from 4 PM - 11 PM with some breaks!) and I think templates should work by default. Also, the default string seems to applicable for Windows so I believe it should be changed on other platforms.

Hello @mlorbetske and thanks for your reply 😃

After installing dotnet 1.1.0-preview1-005077, I feel it would be nice to introduce other arguments instead of -uld to choose one of the EF Core date providers.

If I run dotnet new mvc -h, I would like to see something like these instead of -uld:

  -dp|--data-provider   Entity Framework Core data provider (only applies to Individual auth type)

                        InMemory

                        SQLite

                        LocalDB                                         

                        MSSQL

                        MSSQLCompact

                        MySQL

                        Default: SQLite


  --server              The server to connect to (use with MSSQL or MySQL data providers)

                        string - Optional

                        Default: localhost


  --database            The name of the database (use with MSSQL or MySQL data providers)

                        string - Optional

                        Default: aspnet-Folder name-random text


  --user-id             User id to log in to the date provider (use with MSSQL or MySQL data providers)

                        string - Optional

                        Default: sa (for MSSQL) or root (for MySQL)


  --password            Password for the user id

                        string - Optional

                        Default: Empty string

This will reduce some time spent on looking for connection strings, nuget packages and Classes/methods… but it may give an impression that these are the only supported data providers!

I was hoping to have something similar to Laravel’s database configuration but I forgot that ASP.NET Core is an opt-in framework 😕
