i made all needed with makecert and pvk2pfx to generate the .pfx certificate. Uploaded it in phonegap build and generated the .appx file. But if I upload this file into my windows developer account to publish it up, i get this error:
Package acceptance validation error: You cannot submit pre-compiled .NET Native packages. Please upload the Store appxupload file and try again." .
Do you know how to solve it?
I solved the issue building using a previous CLI. For all people having the same problem, write this in your config.xml :
<preference name="phonegap-version" value="cli-5.4.1" />
Basically, newest CLI has problem with windows phone store.
