"System.InvalidOperationException : To install this application you need either a Windows developer license or a sideloading-enabled system." when deploying Release builds

[WiniumLover]

Hi, I have noticed the below issue when I try to deploy universal app with release build through winium framework but the same issue is not appearing when I deploy universal app with Debug build. I have enabled Sideload apps settings in host system (Windows 10) and enabled developer settings in emulator.

Issue: "System.InvalidOperationException : To install this application you need either a Windows developer license or a sideloading-enabled system." when deploying Release builds

Could you please provide the driver log

If you are using Visual Studio, make sure that there are no notifications regarding license

[WiniumLover]

thanks @NickAb for the reply. I haven't seen such notifications in my Community edition of 2015 Visual Studio. Below is the notification at my side.

[NickAb]

Ok. This was just a guess as I had similar problem due to developer license expiration. Will need to look into this.

Sure @NickAb , when I was debugging found that the issue happened when the framework try to install a file in package "Dependencies" folder.
