Cant find Mono.Android xamarin forms project

Carlos Daza 1

Hello.

I made a cross-platform application with visual studio 2019 community and xamarin forms, then I added GIT as a source code control and I uploaded it to my GitHub repositorie. All the project development was programed in my personal pc and tested on my mobile device.

I installed VS 2019 Community in other PC and added GIT as a source code as well and pull the repositorie of my cross-platform application in that PC. Now the problem im having is that VS cant find the "Mono.Android" reference. Right now i cant build or deploy/debug the app on my movile device.

Hi, i checked for specific files and noticed that some were missing in the project folder hosted in the other PC.

I tried to fix this by copying those files into my drive and paste it in the specific folders of the other project, then re-build the project but it does not work.

I add some screen shots of the missing files:

-Solution (Personal PC)

-Solution (Other PC)

-Folder of the solution (Personal PC)

-Specific folder (Personal PC)

-Specific folder (Other PC)

-Warning (Still showing before and after re-build the solution in the other PC)

It says: Cannot resolve this reference. "Mono.Android" is not assembled. Check if the assembly exist in the disk.

Right now (05-07-2021) I solved the issue.

When I try to clone my github repositorie from Visual Studio 2019 (VS2019) there are two options:

-Clone the repository by giving the URL.

-Clone the repository by browse thru all your GitHub repositories.

The problem I had was that by cloning the repository selecting the second option some files where missing (just how I explained previously).

if I select the first option (clone by giving the URL) the files that were one missing are now downloaded. It seems to work!!!
