title: Why does calling MessageBox.Show hang my application?
body: <p>I have a .NET winforms application that includes this code:</p>
  
  <pre><code>    private void bindingNavigatorDeleteItem_Click(object sender, EventArgs e)
      {
          this.BeginInvoke(new MethodInvoker(DeleteCurrentIssue));
      }
  
      void DeleteCurrentIssue()
      {
          RequestsEntity item = (RequestsEntity)(requestsCollectionBindingSource.Current);
          if (item != null)
          {
              if (MessageBox.Show(this, "Are you sure you wish to delete this request?", "Delete Request", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2) == DialogResult.Yes)
              {
                  RequestsEntity entity = new RequestsEntity(item.RequestId);
                  requestsCollectionBindingSource.EndEdit();
                  requestsCollectionBindingSource.RemoveCurrent();
                  item.Delete();
              }
          }
      }
  </code></pre>
  
  <p>The code stops executing on the MessageBox.Show line BEFORE the message box is displayed.</p>
  
  <p>(The BeginInvoke was added to try to troubleshoot this problem--originally the code was directly in the handler)</p>
  
  <p>My problem seems similar to:
  <a href="https://stackoverflow.com/questions/24773452/messagebox-hangs">MessageBox hangs</a></p>
  
  <p>If I remove the parent window of the MessageBox (no 'this' parameter) then I only get the hang about 10% of the time.  </p>
  
  <p>I presume this is a concurrency problem and something is blocking my UI thread.  One more interesting tidbit--if I press the ALT key once, the MessageBox appears and I can proceed with my program.  </p>
  
  <p>UPDATE:</p>
  
  <p>Here's the trace.  It looks like my UI controls and ORM are interacting in a problematic way.</p>
