Hope You are doing well.Actually i have created one windows phone 8 application. So for testing i have installed the.xap file locally into windows phone 8 and it is working fine. But if i am going to install that.xap package in windows phone 8.1 or later it is not getting installed.I have made research and found that the windows phone 8.1 and later OS version devices are accepting the APPX Package. They will not allow to install.XAP locally. Now the scenario is like that my client wants to test this application in windows phone 8.1 device.So, Can anyone help me out that how can we install locally XAP package into windows phone 8.1 device?Awaiting Response.
