    A geodatabase-related exception has occurred.
    This method or property must be called within the lambda passed to QueuedTask.Run
    Remarks
    The moment passed into this routine has different meanings, depending on the type of versioning in use:
    • Traditional versioning - database time (local time of the database server)
    • Branch versioning - UTC time
    Example
    Switching between versions
    public void ChangeVersions(Geodatabase geodatabase, string toVersionName)
    {
      using (VersionManager versionManager = geodatabase.GetVersionManager())
      {
       VersionBaseType versionBaseType = versionManager.GetCurrentVersionBaseType();
    
       if (versionBaseType == VersionBaseType.Version)
       {
         Version fromVersion = versionManager.GetCurrentVersion();
         Version toVersion = versionManager.GetVersion(toVersionName);
         
         // Switch between versions
         MapView.Active.Map.ChangeVersion(fromVersion,toVersion);
       }
    
       if (versionBaseType == VersionBaseType.HistoricalVersion)
       {
         HistoricalVersion fromHistoricalVersion = versionManager.GetCurrentHistoricalVersion();
         HistoricalVersion toHistoricalVersion = versionManager.GetHistoricalVersion(toVersionName);
         
         // Switch between historical versions
         MapView.Active.Map.ChangeVersion(fromHistoricalVersion, toHistoricalVersion);
       }
    
       // Switch from HistoricalVersion to Version and vice-versa 
       // MapView.Active.Map.ChangeVersion(fromHistoricalVersion, toVersion);
       // MapView.Active.Map.ChangeVersion(fromVersion, toHistoricalVersion);
    
      }
    }
