there suggested run code in windows 8 because windows speech library has hard dependency on windows 8's network stack. followed , executed code on windows 8 same error persists. can me error. attached snapshots of details of xamlparseexception on win7 , win8.

i had same problem. running code on machine different development machine. installed visual c++ redistributable packages (http://www.microsoft.com/en-us/download/details.aspx?id=40784), rebooted, , resolved issue.

i'm not sure if fix issue or not, worked me! (note installed them visual studio versions 2013 , 2015.)
