Error while trying to edit code in debugging mode in VS2013

Question

I'm a C# programmer and recently I've installed Visual Studio 2013. The problem is when i set a break point or get an error and trying to edit the codes while debugging I get this error and I couldn't find the same error searching on Google.

Changes are not allowed for this module as it was not built for changes while debugging or the target .NET runtime version does not support it

I also tried to check the options on Tools -> Options -> Debugging -> Edit and Continue, But didn't help.

Any idea what the problem is?

Answer 1

To edit a C# program while you're running it in Visual Studio 2013:

1. Go to Project, Properties, Build.
2. Set Platform target: x86
3. Disable "Optimize code"
4. Set Advanced, Debug Info: Full

Answer 2

I came across the same issue and found that "solution configuration" on the top bar was changed to Release from Debug,because I build the last version into Release folder.Changing back to Debug mode will solve the issue.
