HI thanks, That solved the initial errors (didn't see that before, sorry) However when building the solution I am now getting this error:

Error1The "GenerateWinPRTManifest" task failed unexpectedly.

System.Xml.XmlException: An error occurred while parsing EntityName. Line 4, position 224.

I have looked online and cannot find a solution to this.

Again thanks for your help.
