SourceLink needs updates for API changes #2017
Description
The Arcade update flow into installer came up with some errors I think we've seen before:
/vmr/src/sourcelink/artifacts/source-build/self/src/src/dotnet-sourcelink/Program.cs(91,17): error CS0144: (NETCORE_ENGINEERING_TELEMETRY=Build) Cannot create an instance of the abstract type or interface 'Option'
/vmr/src/sourcelink/artifacts/source-build/self/src/src/dotnet-sourcelink/Program.cs(93,21): error CS0122: (NETCORE_ENGINEERING_TELEMETRY=Build) 'Option.Argument' is inaccessible due to its protection level
/vmr/src/sourcelink/artifacts/source-build/self/src/src/dotnet-sourcelink/Program.cs(95,17): error CS0144: (NETCORE_ENGINEERING_TELEMETRY=Build) Cannot create an instance of the abstract type or interface 'Option'
I think you've helped us fix these downstream errors before - could you help out again? Thanks!
