Discovering a Windows 2008 server and a Windows 2003 server in C #

Question

Can someone help me modify this code to support Windows 2003 and Windows 2008? Thanks

 public static string getOSLegacy()
       {
           //Get Operating system information.
           OperatingSystem os = Environment.OSVersion;
           //Get version information about the os.
           Version vs = os.Version;

           //Variable to hold our return value
           string operatingSystem = "";

           if (os.Platform == PlatformID.Win32Windows)
           {
               //This is a pre-NT version of Windows
               switch (vs.Minor)
               {
                   case 0:
                       operatingSystem = "95";

                   case 10:
                       if (vs.Revision.ToString() == "2222A")

Answer 1

2003 - 5.2. 2008 - 6.1.

Edit: This answer is incomplete, as noted by the comments. Slavik's answer , and the related article is a much better IMHO approach. In particular, the wProductType byte (which is missing from the .NET API) contains key information.

Answer 2

Server 2003 5.2.3790.131072. 2008 6.0.6002.131072.

After looking at the parameters, I found several links (surprisingly few compared to the application manifest) that instead suggested using a registry search.

Check out this diagram from MS regarding comparison with OS releases: https://msdn.microsoft.com/en-us/library/windows/desktop/ms724832.aspx
