    public Geodatabase ConnectToVersion(Geodatabase geodatabase, string versionName)
    {
      Geodatabase connectedVersion = null;
    
      if (geodatabase.IsVersioningSupported())
      {
        using (VersionManager versionManager = geodatabase.GetVersionManager())
        using (Version version = versionManager.GetVersion(versionName))
        {
          connectedVersion = version.Connect();
        }
      }
      return connectedVersion;
    }
    Working with Versions
    public async Task WorkingWithVersions()
    {
      await ArcGIS.Desktop.Framework.Threading.Tasks.QueuedTask.Run(() =>
      {
        using (Geodatabase geodatabase = new Geodatabase(new DatabaseConnectionFile(new Uri("path\\to\\sde\\file"))))
        using (VersionManager versionManager = geodatabase.GetVersionManager())
        {
          IReadOnlyList<Version> versionList = versionManager.GetVersions();
    
          //The default version will have a null Parent
          Version defaultVersion = versionList.First(version => version.GetParent() == null);
    
          IEnumerable<Version> publicVersions = versionList.Where(
            version => version.GetAccessType() == VersionAccessType.Public);
          Version qaVersion = defaultVersion.GetChildren().First(
            version => version.GetName().Contains("QA"));
    
          Geodatabase qaVersionGeodatabase = qaVersion.Connect();
    
          FeatureClass currentFeatureClass = geodatabase.OpenDataset<FeatureClass>("featureClassName");
          FeatureClass qaFeatureClass = qaVersionGeodatabase.OpenDataset<FeatureClass>("featureClassName");
        }
