I have Windows RT tablet with 8.1 update. I'm trying to build both 8.0 and 8.1 versions of my app. I have no problem deploy my app from Visual Studio 2013 (windows 8.1 version) onto the device. But when I try to deploy the app from Visual Studio 2012 (windows 8.0 version), it says:
Unable to connect to the Microsoft Visual Studio Remote Debugging Monitor named 'tablet:4018'. The remote debugger is not an acceptable version.
Remote Tools 2012 refuse to run on the 8.1 tablet, it says the .dll signature are not compatible, or so.
