Best practice for reusing SqlConnection

Hope this helps Creating a new instance of the class SqlConnection does not create a new network connection to SQL Server, but leases an existing connection (or creates a new one). .NET handles the physical connection pooling for you.
When you have finished with your connection (through which you can send multiple queries) just Close() or Dispose() (or use a using{} block preferably).

Reusing SqlConnection within a DAL method

fixed the issue. Will look into that further The real problem is not the connection, but the transactions. When a logical operation involves multiple DAL physical operations, usually they have to be part of a transcation. Unless corectness is optional... If a transaction spans multiple connections then it has to be elevated to a distributed transaction, with disastrous perofrmance results. So when designing a DAL, always thrive to affinitize a transaction to a connection. This ripples through the DAL API design, as usually the result is that the conneciton and transaction objects have to be explictly handed out to the DAL methods, either as individual parameters or as a 'context' object that aggregates them.

this one helps. Sql Connections are pooled so if you are concerned with performance; chances are that both methods will use just one connection and therefore, the penalty for using the second approach is negligible.
On the other hand, the second approach shows better encapsulation and separation of concerns. I would go with the second option.

this one helps.
Is this just because they were being brief with the code, or is there a reason they're not worth handling here? are they possibly handld by the using construct in some way?
Reusing SqlConnection in multiple ninject bindings

I think the issue was by ths following , Create a binding for your SqlConnection rather than instantiating one:
code :
Bind<SqlConnection>().ToConstant(new SqlConnection(ConfigurationManager.ConnectionStrings["widgetsConn"].ToString()));

Bind<IRepository<Widget>>().To<SqlRepository<Widget>>().InSingletonScope().WithConstructorArgument("connection", context => Kernel.Get<SqlConnection>());
Bind<IRepository<Credential>>().To<SqlRepository<Credential>>().InSingletonScope().WithConstructorArgument("connection", context => Kernel.Get<SqlConnection>());

To fix the issue you can do The method is fine but all the try/catch/finally is not needed. This is what "using" does. Let alone that you have potential null reference if the conn object is not constructed successfully.
