i have an error .
What does this mean and what to do about it ?
Well it seems i solved the problem.
I removed the Android.dll here "obj\Release\90\Ouderijn.Android.dll;obj\Release\90\Ouderijn.Android.dll"
And when i build there is a new one and no problem anymore .
put code please!
The problem is that i dont know where to look .
Does not matter what i open every time the error.
Open Properties ,then error.
Build , then error.
Open Xaml page , then error.
Or add new page or existing what ever , always the error.
It is an app that i made and is in test fase in Playstore , when adding something that does not work or is nice then after some test i remove the project and put the original from a external harddrive back.
Maybe there is the problem coming from ?????
(1) Have you restarted Visual Studio?
(2) Have you rebooted your PC?
(3) If you create a new solution using the "Mobile App (Xamarin.Forms)" template, do you get the same error? If so, you'll probably need to repair your Visual Studio installation.
Restarted both a few time's and when i start a new programm or download example then there is no error .
Can i do something with Build actions ?
Using Visual Studio for a few year for making programm's for windows pc, but i am very new with making app's
Using Visual Studio 2019 version 16.3.2
New project everything is oke
Can you provide a demo that could re-produce this issue? If not, you can create a free case.
Still working on the error and found this now.
do i have to remove something , build or rebuild is not working anymore
