VS 2010 and framework 2.0

Hello,

I'm a newbee in VS.

I developed a small aplication oo on VS 2010 C# framework 4.0 based on windows forms.

I need to compile it to framework 2.0 First I tried to compile with framework 2.0 on VS 2010 and it failed then I installed VS 2008 side by side and also failed.

The error message on VS 2008 framework 2.0 is :

An error occurred creating the configuration section handler for userSettings/WindowsFormsApplication4.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. (D:\MG\Visual Studio 2010\WindowsFormsApplication4\WindowsFormsApplication4\bin\Debug\WindowsFormsApplication4.vshost.exe.Config line 5)

The error message on VS2010 framework 2.0 é :

An error occurred creating the configuration section handler for userSettings/WindowsFormsApplication4.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. (D:\MG\Visual Studio 2010\WindowsFormsApplication4\WindowsFormsApplication4\bin\Debug\WindowsForm

How to compile it on framework 2.0 ?

In Visual Studio select Project > <yourproject>Properties from the main menu. In the dialog that appears, switch to "Application" then under the "Target Framework" dropdown select ".NET Framework 2.0".

Did you create the application directly with targetframework set to 2.0 ?
Did you add references to .net 4.0 components ?

Hello Carl,

Thanks,

The targuet framework was already 2.0.

The application was created on framwork 4.0. When I changed the targuet framework to 2.0 I didn't suceed to compile on VS2010 neither VS2008.

Ok, then that suggests you are referencing some non-2.0 components. By the way, why do you need to target 2.0 if it was originally built for 4.0?

This app should run on a ws2003 with framework 2.0 (only). How to check if I'm using non 2.0 components ?
