I want to debug a SQLCLR stored procedure in SQL Server. I have been trying to debug an SP in VS2015 Community and in the recently installed VS2017 Community editions without success. I am pretty sure that the problem lies in attaching to SQL Server but as I've done everything I can find mentioned online but to no avail.

When creating the database project in SQL Server Express LocalDB everything works fine. If I change the connection string to use my Developer Edition SQL Server, I then get an error. I have done the following:

  1. I created a new database. I am the only user of the server and it resides on the same desktop machine that I am using for Visual Studio.

  2. In Visual Studio I created a simple database project with a simple method to send some text to the output pipe.

    [Microsoft.SqlServer.Server.SqlProcedure]
public static void mytest ()
{
    SqlContext.Pipe.Send("in clr Craig1");
}
  3. I edited the Target Connection String in the project properties to connect to the new database and successfully got a connection when pressing the connection button. The connection string used Windows Authentication for me, with the same user as the database owner.
  4. I built and deployed the solution and checked the SQL Object Explorer to ensure that the SP was deployed. It was.
  5. I selected the server and, using the right click, selected the "Allow SQL/CLR Debugging". I checked it again to ensure it was actually set.
  6. I selected the stored procedure and with the right click, selected "Debug Procedure..."
  7. The debug script was displayed. I stepped to the line to exec the SP and then pressed F11 to step in. At this point I was shown the following: enter image description here
  8. I pressed the attach and was shown the following error: enter image description here

Thereafter, the procedure executes and performs the pipe function, but it does not let me do the attachment and the debugging.

Any ideas of what I'm doing wrong? Thanks Craig

You might just need to start Visual Studio with "Run as Administrator". I do not believe that I needed to do that when running Windows 8, but I am running Windows 10 now and definitely need to "Run as Administrator". I am guessing that you cannot otherwise attach to someone else's process (I have my Developer Edition running with a service account of "SQL Server", yet LocalDB always runs as the Login that started it, typically yourself). I have not tested to see if running Developer Edition as myself would still require "Run as Administrator", or how running Developer Edition as "Local System" would affect this behavior.
