Error Creating Debug Information - Code Won't Compile

Question

I\'m using VS 2008. When ever I make a change in my code and try to compile I get the following error:

Error 7 Unexpected error creating debug informa

Answer 1

I had the same problem this morning and noticed that I had another project open that had a reference to the one that would not compile or debug. I removed the reference (as I didn't actually need it) and it was fine.

Answer 2

This works for me with web projects in Visual Studio Express 2012 for Web:

1. Press F5 to begin debugging
2. "Do you want to execute last successful build?" - hit YES
3. At this point you could try a request - not sure if this step is necessary
4. Hit the stop button
5. Recompile successfully

Answer 3

I have solved a similar problem by adding these lines as a pre-build event:

if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked"

With proper modifications, it might help your problem.

Answer 4

Have you tried closing VS, deleting obj folder then restarting VS?

Answer 5

I just came across the same problem today. And then I realized what went wrong: I had couple of Visual Studio windows opened at the same time, and one of them was in debug mode.

When I stopped debug mode in that one, the problem was solved.

That happens when you have a "fistfull of VS windows" opened.

Answer 6

I had this issue today. In my case, I had just grabbed the data from my company's source control and instantly hit this issue when I tried to compile the project. The issue ended up being that the \bin folder was set to Read Only. To solve the issue, I just made the folder not Read Only.
