VS - difference between F5 and CTRL + F5, or how to find the error

That took a lot of nerves now. Actually I should make a release build and the check in. From sheer habit I have launched the executable then times and found that did not want the application. How to not? Well, that was it now to find.

So I put the debug configuration and pressed F5. The application started without errors. A double-click on the EXE or a CTRL + F5, the application did not want. :-(

First I tested then all directories on a read-only. There was nothing read-only.

Because I got only a generic error that unfortunately say anything where what happened I had to painstakingly me browse until I was there where it bum made. I could debug yes. MessageBox.Show ("Hello x") where it still did I looked.

Eventually I ended up here.

protected override DbConnection CreateConnection 
(string connectionString) {
	return new SqlConnection(connectionString);
}}

Now I could everything in a try {} catch() block Pack and see what was exactly the mistake.
