Captures a very simple reproduction for debugging. The issue appears where a newly created netcoreapp2.1 targeted project cannot build blaming missing assemblies (including System). Following these equivalent steps on a Windows 10 machine with .NET Core SDK 2.1 installed works flawlessly.
- clone this repo
- check out the branch named master (you are likely already here) or named start-here (in case master has moved)
- run the create.sh script
dotnet new console --name should-build --framework netcoreapp2.1
cp clean.sh ./should-build
cp fail-to-build.sh ./should-build- cd into the should-build folder
- run the clean.sh script
rm -rf obj
rm -rf bin- run the fail-to-build.sh script
dotnet restore
dotnet build- observe the issue
Expected result : successful restore, successful build
Observed result : successful restore, failed build
