how to get the target .net framework for Rebex.common.dll

Question

Hello,

I want to get the target .NET Compact Framework for Rebex.common.dll of CE.

In C# coding when i check the TargetFramework attribute for the assembly it always return 4.0 but i expect it to return the .NET Compact Framework 3.5. Is there any way to get this information by using c# coding?

Although when check the properties of dll by right click on it. The description field tells that its .NET Compact Framework 3.5

Thanks

The most simple way to determine the .NET CF version targeted by a Rebex DLL is to use .NET's FileVersionInfo to retrieve the "description", which includes the platform name:

public static Version GetCompactFrameworkPlatform(string assemblyPath)
{
    var info = FileVersionInfo.GetVersionInfo(assemblyPath);
    string description = info.FileDescription;
    if (description.EndsWith(" for .NET Compact Framework 3.9", StringComparison.Ordinal) ||
        description.EndsWith(" for .NET CF 3.9", StringComparison.Ordinal))
    {
        return new Version(3, 9);
    }

    if (description.EndsWith(" for .NET Compact Framework 3.5", StringComparison.Ordinal) ||
        description.EndsWith(" for .NET CF 3.5", StringComparison.Ordinal))
    {
        return new Version(3, 5);
    }

    if (description.EndsWith(" for .NET Compact Framework 2.0", StringComparison.Ordinal) ||
        description.EndsWith(" for .NET CF 2.0", StringComparison.Ordinal))
    {
        return new Version(2, 0);
    }

    return null;
}

This code is suitable for Rebex DLLs published in 2017 or later.
