Sorry Andrew. Same issue. I appreciate the effort though. One thing I forgot to mention or that I thought wasn't relevant, is that the LinqToRdfDesigner installation always seems to hang at the end for about 30 seconds. Never any installation errors.
Anyway, with this new version I do get much further:
1) Now I see a new project type - LinqToRdf Project
2) I'm able to create a new project based on this template.
3) But when I double-click the LinqToRdf.rdfx file, i now get the 2 error messages attached (screen prints)
4) After clicking 'No' to each (to stop loading in the future), the rdfx file is shown in XML (also attached)
Hope that helps. I'm much farther with this version....
Thanks.
Steve
