In a .NET 2.0 C# application I use the following code to detect the operating system platform:
string os_platform = System.Environment.OSVersion.Platform.ToString();
This returns "Win32NT". The problem is that it returns "Win32NT" even when running on Windows Vista 64-bit.
Is there any other method to know the correct platform (32 or 64 bit)?
Note that it should also detect 64 bit when run as a 32 bit application on Windows 64 bit.
