Upgrading the PowerServer project
After applying Build 1900, for PowerServer projects to work correctly, you will need to
1) Upgrade the PowerServer project by following instructions in Upgrade the PowerServer project.
2) Upgrade the PowerServer NuGet packages and then re-publish your solution. Refer to Upgrade PowerServer NuGet packages for how to manually upgrade NuGet packages in the solution.
3) The solution settings have not been changed in Build 1900 (compared to Build 1892), so there is no need to update the solution settings.
