Update Lineage Os in a oneplus 2

The instructions posted here in the Lineage OS web site regarding the update of oneplus do not work for me, I can't get the command adb reboot sideload to work, it simply reboots my phone.

So these are the steps I took to update my phone to the latest version.

    1. Restart phone in recovery mode:

        power + volume down (will also take screenshot, just wait)

     or
        adb reboot recovery

    2. In TRW select Advanced > ADB sideload > slide to start sideloading

    3. Run command

    adb sideload .\lineage-17.1-20200601-nightly-oneplus2-signed.zip
wait...takes some time, you should see progress indicator
    4. In TRW select ADB sideload and run command
adb sideload .\open_gapps-arm64-10.0-nano-20200530.zip
    5.Reboot.. Wait a long time

Visual studio: Class from XML or json

Visual studio has a nice hidden feature, that it is able to generate classes from XML and JSON data.
To be able to use you need:

1. Create an empty class file (.cs file)
2. Copy the JSON/XML to the clipboard
3. Go to Visual Studio -> Edit -> Paste Special -> Paste as class

and you will be left with a nice class.
