Possible to run .NET 4.0 app on 3.5 Installed platform? RRS feed

  • Question

  • Hi,

    Is there ANY way I can target the 3.5 platform while using 4.0 libraries (as 3.5 doesn't seem to include the WPF DatePicker, DataGrid and a few other things)?

  • No. If you are using 4.0-unique features, you must target 4.0.

  • Hi Omar Mir,

    The degree of .NET Framework support for backward and forward compatibility is version-specific. The .NET Framework supports both backward and forward compatibility for applications created using version 1.1 only. It does not support forward compatibility in applications created using version 2.0.

    The .NET Framework provides a high degree of support for backward compatibility. However, for forward compatibility you might need to modify an application so that the application runs as expected.

    If you have any concerns, please feel free to let me know.
