I am going to upgrade TargetFramework for our client projects but they used French language for their development. But we are using English language over here. Now when I upgrading target framework then resource designer file comments changed from French to English. Resource designer file comments in framework 4.0

<summary>
///   Une classe de ressource fortement typée destinée, entre autres, à la consultation des chaînes localisées.
/// </summary>

After upgrading TargetFramework by using project properties drop down it change to

/// <summary>
///   A strongly-typed resource class, for looking up localized strings, etc.
/// </summary>

Can you please help me how can we keep Visual Studio auto generated comments in French language what steps I need to take to handle this?

Is it possible that, If I install 4.5.2 framework in French and English languages in my machine. Then When I select targetframwork from drop-down at that time, I can specify which language I need to migrate French or English?

These are Custom resource files like EmployeeException.resx file. Now the content of that file does not change. it is still in french language but its designer file MEGExceptionMessages.Designer.cs has been changed to English translation. As these are supported files for Visual Studio so I think it convert automatically by that due to framework change..
