I'm pretty sure it would only error out if the data overflowed the target field. So it might appear to work as long as the values are small enough

Is it possible you mixed up varchar and nvarchar somewhere? If you assign a varchar(15) with an nvarchar(15) you might get that error

I don't know of a way to upload it here.

It definitely sounds like you have a race condition happening here. Running the project while debugging probably slows it down enough to work. If your app is multi threaded or you're using methods like BeginRead and BeginWrite, you need to make sure the previous operation is finished before starting the next.

I hope that helps, I can't suggest anything specific without seeing the code.

It could be a permissions issue. If you are running Visual Studio in an administrative mode, but when you run the installed app, it might be running with fewer priviledges. It might also be a problem if anything like System.Diagnostics.Debug.Equals is being used since it will not be called when the code is compiled with release configuration.

I still think the problem is probably with the file manager class. Would it be possible to see the entire code for that; the read and write functions at least.
