5.0 SDK requires an explicit reference to System.IO.Pipelines for a 3.1 classlibrary targeted ASP.NET Core

See original GitHub issue

I’m getting errors like this when building with the .NET 5.0.100-rc.1.20452.10 SDK:

/Users/ryan/github.com/dapr/dotnet-sdk/src/Dapr.AspNetCore/DaprEndpointRouteBuilderExtensions.cs(47,72): error
CS0012: The type 'PipeWriter' is defined in an assembly that is not referenced. You must add a reference to assembly 
'System.IO.Pipelines, Version=4.0.2.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. [/Users/ryan/github.com
/dapr/dotnet-sdk/src/Dapr.AspNetCore/Dapr.AspNetCore.csproj]

when building a project that:

targets netcoreapp3.1
is a class library
references Microsoft.AspNetCore.App
uses PipeWriter in code
does not explicitly reference the System.IO.Pipelines package

Example project: https://github.com/dapr/dotnet-sdk/blob/master/src/Dapr.AspNetCore/Dapr.AspNetCore.csproj

This is regression from the 3.1.301 SDK - which builds these projects successfully on the CI: https://github.com/dapr/dotnet-sdk/runs/1221898037?check_suite_focus=true

I can work around the problem by adding an explicit reference to the System.IO.Pipelines package (and I will do) - but it seems like this old bug came back.

@wli3 we should also ensure this is covered in tactics so folks are both aware and remember to do this as I don’t want to have to remember to remind people.

Closing as the change to the installer repo has been merged.
