    I have recently noticed that my xamarin.forms current version is obsolete (4.0.0) and it cause me bugs when coding so I want to update to the latest version of xamarin.forms but when doing the mentioned action i get the following error:

    Unhandled Exception:

    System.MissingMethodException: Method not found: void .ResourceLoadingQuery.set_Instance(object) occurred

    and when capturing with a catch block, the specific message says:

    Method not found: void .ResourceLoadingQuery.set_Instance(object)

    I dont understand what does this means, what method in my implementation i am missing, does anyone knows how to solve this?

    This is a problem which can occur when there is an old version of a DLL still lingering somewhere around. Update all the forms version of each platform and do some clean instruction like: Delete the bin/obj folders, rebuild the solution. If it persists try to remove the forms nuget and readd the latest one.
