Add an existing file to a project without copying it

If you want to add an existing file to a project and have the project point to the file where it resides, press the little arrow key on the right side of the add button on the add existing dialog.  The arrow will present a small context menu that allows the option of adding the file as a link, which will cause the Visual Studio project to point to that file where it is instead of copying it to the project directory.

Debug SQL Server (Stored Procedures or Functions)

SQL statements can be difficult to diagnose and debug. SQL Server does not include any default way to debug and step through a stored procedure, but Visual Studio does. Using the Server Explorer, you can step through the execution of a stored procedure or function right inside of Visual Studio. The first step is to open the Server Explorer and create a data connection to your database.

You will then see the stored procedures and functions of your database listed in the Server Explorer.

From the Server Explorer, you can right-click on a stored procedure or function and you will see a menu item named Step Into Stored Procedure,

When you select Step Into Stored Procedure, you will see the Run Stored Procedure dialog,

After specifying the values for any parameters the stored procedure has, click the OK button. Visual Studio will now execute the stored procedure and open it in the document window, stopping in the first line of execution.

You can now step through the stored procedure as it executes. You can set breakpoints just as you would in normal code—the only limitation is that you can specify only location and hit count breakpoints.

Because T-SQL is inherently different than .NET languages, the debugging experience is a little bit different. Here are some of the limitations with SQL debugging:

  • You can use only location and hit count breakpoints in T-SQL stored procedures and functions.

  • You cannot use Step Into to step from .NET managed code to T-SQL. You can set breakpoints in the stored procedure though, and the debugger will break when it comes across them.

  • You cannot use Break while a SQL statement is already running.

  • You can’t use the Set Next Statement function as you might in managed code.

Some other differences are the facts that you can’t use the memory or registers windows, as they just don’t apply to SQL. Unfortunately, SQL Print statements are not shown in the output window either.

You cannot run triggers directly, but you can set breakpoints in triggers, and if they are triggered, Visual Studio will break into their execution on those breakpoints.
