Hello :

     I got one trouble after I upgrade from WPF 2008 v2 to 2009 V1. I follow the upgrade procedure suggested by the quick start.

   After I change all WPF reference and delete the licenses  I rebuild the project  and compile error shows that "LC.Exe closed return by -1". I check the error message when google from internet and find that it was because the 3rdparty assemblies.

   I have been upgrade from 2008 V1 to 2008 V2 smoothly and did not encounter any problem in the same WPF project.

  my last assembly version is 8.2.20082.2001.

 Did anyone encounter the same problem?
