Nuget Packages needs to be restored.

Shubham Agrawal 1

Hi Everyone,
I did a fresh installation of Mac Os 10.13.6 and then I installed the visual studio 2017 on the Mac machine but after the installation I create a new project.when I opened that project I am getting the below error..
Nuget packages needs to be restored before building. Nuget MSbuild targets are missing and are needed for building. The nuget MSbuild target are generated when the nuget packages are restored

And when I click on the packages folder of the iOS and Android projects there was a yellow mark.on the packages..
Please help me to resolve the issue.

macOS 10.13 will reach end of life in Jan 2021 (less than two months), so try to upgrade. Right click on the Packages node and you should see the menu items you wanted.

@Shubham Agrawal We strongly recommend you to upgrade macos and install visual studio 2019 , it could avoid many potential issues.

Same issue here with latest VS for Mac installation. Even when adding a new .netstandard class library to the project I cannot build it because of this error. Restoring the packages for this project alone results in the following error: `/Applications/Visual Studio.app/Contents/Resources/lib/monodevelop/bin/MSBuild/Current/bin/NuGet.targets(335,5): error MSB4181: The "MSBuild" task returned false but did not log an error. [/var/folders/g6/g90t1zn53tn59f3bws21l5zw0000gn/T/NuGetScratch/j3fzihx4.j3n.nugetinputs.targets]

MSBuild exited with code 1`
