WPF freezes when dragging data source onto a Page or Window


WPF freezes when dragging data source onto a Page or Window

Possible Solution

Inspect datasource and see if it has a child table underneath it. Does this child expand to show the parent table again. If so then you may be creating an infinite loop when dragging the datasource onto the Page or Window

Setting up Microsoft Lync from Office 365

After installing Lync on my 64-bit PC using 64-bit intall it would not connect.

Cannot sign in because the server is temporarily unavailable. If the problem continues contact your support team

Solved with the steps on this site:



Configure the Lync settings

  1. In the upper-right area of Lync 2010, click the Gear icon to open the Options page.
  2. In the Lync – Options dialog box, click Personal.
  3. Next to the sign-in address, click Advanced.
  4. Make sure that Manual Configuration is selected and that the configuration values are exactly as follows:

Internal server name or IP address: sipdir.online.lync.com:443
External server name or IP address: sipdir.online.lync.com:443

I did not need to change the firewall. So any changes I had tried, I reversed and removed.
