Hello,
I'm using VS2012 + Windows Phone SDK 8. I try to open a new WIndows Phone project (or open some sample project downloaded from MS Web): I can edit the project, I can compile, but I cannot run it.
"debug" tab in project properties reports "an error occurred trying to load the page. The specified propery cannot be found".
If I try to run using F5, it reports: "Error Value cannot be null. Parameter name: key"
so I cannot run nothing!
Any idea?
Moreover: I did try on an other PC, similar environment, and I have same trouble!
tha nks
