Detect my version of dotnet

Question

How can I test a C # application, which version of dotnet is used by the application?

Use Environment.Version - it gives the exact version of .NET that launches the application.

Returns a Version object that describes the major, minor, string, and revision numbers of the common language runtime.

Create a console application add this class and run it

  using Microsoft.Win32; using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication2 { public class GetDotNetVersion { public static void Get45PlusFromRegistry() { const string subkey = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\"; using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey(subkey)) { if (ndpKey != null && ndpKey.GetValue("Release") != null) { Console.WriteLine(".NET Framework Version: " + CheckFor45PlusVersion((int)ndpKey.GetValue("Release"))); } else { Console.WriteLine(".NET Framework Version 4.5 or later is not detected."); } } } // Checking the version using >= will enable forward compatibility. private static string CheckFor45PlusVersion(int releaseKey) { if (releaseKey >= 394802) return "4.6.2 or later"; if (releaseKey >= 394254) { return "4.6.1"; } if (releaseKey >= 393295) { return "4.6"; } if ((releaseKey >= 379893)) { return "4.5.2"; } if ((releaseKey >= 378675)) { return "4.5.1"; } if ((releaseKey >= 378389)) { return "4.5"; } // This code should never execute. // that 4.5 or later is installed. return "No 4.5 or later version detected"; } } // Calling the GetDotNetVersion.Get45PlusFromRegistry method produces // output like the following: // .NET Framework Version: 4.6.1 }
