Connect the DAL and Controller

Inject the DAL into the controller

Within your controller, add a property of the type of whatever your DAL is called (e.g. DataContextDapper or DataContextEF), then add a constructor and assign it to a new DAL object and pass in config -

private DataContextDapper _dapper;
    
public UserController(IConfiguration config)
{
    _dapper = new DataContextDapper(config);
}

Example using Entity Framework -

private DataContextEF _entityFramework;

public UserEFController(IConfiguration config)
{
    _entityFramework = new DataContextEF(config);
}

Test the Connection

Then create a new endpoint to test the connection -

[HttpGet("TestConnection")]
public DateTime TestConnection()
{
    return _dapper.LoadDataSingle<DateTime>("SELECT GETDATE()");
}

Note:: _dapper is named with an underscore as this is a common c# naming convention for private fields. This helps to quickly differentiate between private fields and local parameters or variables
