I used NetRflector to de-compiler an existing in-house application (because our developer didn't leave any documentation or original source). Because the de-compiler created the App.config with almost empty lines (i.e. no binding string/connection, etc.) so I copied the whole content from the file applicationname.exe.config (located in the same folder of the file applicationname.exe); Then using Visual Studio 2013 Pro. recompiled the application. Recompilation is smoothly without any error message or warning. However I got error message (below) when running it

Please advise me!

Thanks so much,
