backgroundWorker.RunWorkerAsync();
CandidateView candidateView = null;
foreach (object view in **this.RegionManager.Regions["R1"].Views**)
{
if (true == view is CandidateView)
{
candidateView = view as CandidateView;
break;
}
}
if (null == candidateView)
{
candidateView = this.Container.GetExportedValue<CandidateView>();
this.RegionManager.Regions["R1"].Add(candidateView);

this.RegionManager.Regions["R1"].Activate(candidateView);
}
The composition produced a single composition error. The root cause is provided below. Review the CompositionException.Errors property for more detailed information. 1) The region manager does not contain the R1 region. Resulting in: An exception occurred while initializing module 'CandidateMModule'. - The exception message was: The region manager does not contain the R1 region. - The Assembly that the module was trying to be loaded from was:Candidate, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null Check the InnerException property of the exception for more information.
