In my application I am using user settings as explained here. Then I realized that in VS 2010 I was using .NET 4.0 while only .NET 2.0 was sufficient.
When I changed the framework and build the project, in my code whenever I access setting now, I get the following error:
An error occurred creating the configuration section handler for userSettings/Vegi_Manager.Properties.Settings: Could not load file or assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified. (C:\Users\AKSHAY\AppData\Local\Microsoft\Vegi-Manager.vshost.exe_Url_44035dlkzpfaaauiqsd4nh3f0l0yq0tv\1.0.0.0\user.config line 5)
It is for unknown reasons using version 4.0. Please suggest what should I do.
Check out your app.config maybe you still have System.Configuration.UserSettingsGroup or something of that sort of version 4 still lurking around, you will have to manually edit and get the relevant for version 2
