Here is the snippet: public string GetAppVersion() { var assembly = Assembly.GetExecutingAssembly(); var name = assembly.FullName; var nameComponents = name.Split(','); if (nameComponents.Length >= 2) { var versionComponent = nameComponents[1]; var keyAndValue = versionComponent.Split('='); if (keyAndValue.Length == 2) { var value = keyAndValue[1]; var versionBits = value.Split('.'); if (versionBits.Length >= 3) { return String.Format("{0}.{1}.{2}", versionBits[0], versionBits[1], versionBits[2]); } } } return String.Empty; } Available as a Gist as well.
