Package coverlet.console 3.0.0 is not compatible with netcoreapp3.1

[vladislavzl]

I can't install coverlet.console 3.0.0 for mcr.microsoft.com/dotnet/core/sdk:3.1 image:

error NU1202: Package coverlet.console 3.0.0 is not compatible with netcoreapp3.1 (.NETCoreApp,Version=v3.1) / any. Package coverlet.console 3.0.0 supports: net5.0 (.NETCoreApp,Version=v5.0) / any

Is it expected behavior for a new release?

[MarcoRossignoli]

Yep we moved .NET Tool to last version. We'll move .NET tool to last version every time we can.
.NET 5.0 is not a LTS(expires in February, 2022) but we'll move to next one on next releases https://github.com/dotnet/core/blob/master/releases.md

OK, but .Net Core 3.1.10 is LTS and expires December 2022

Yep I know, the idea was move to 6 next year and release with 5 because is the first "unified version".

Do you have a problem with 5.0, some restrictions?

[HughPH]

We have a good number of services that were created targeting .net core 3.1.10, and we wouldn't want to update them all in bulk. This just means, really, that we are restricted to Coverlet 1.7.2 until we make a coordinated effort to migrate to .Net 5.0 - which is not an ideal situation.

The converse question is whether there are certain new Coverlet features that are incompatible with .net core 3.1.10?

[MarcoRossignoli]

It's not clear to me why it's a problem, coverlet console is a .NET tool that instruments and after that runs you command+args(using standard Process.Start) you don't need to upgrade you project to .NET 5 only install on local machine/ci.

Can you elaborate?I mean the only problem I see is if there are restrictions on software you can install on CI/local.

.NET 5 is the runtime that runs coverlet tool not your tests.

[HughPH]

OK, let me dig into it and get a clear answer for you. It might be that we have a reference to coverlet.console where we actually need the other coverlet packages.

Several people have come up against this now because it's been installed as a package in projects that target netcoreapp31, so it would benefit us all if there's a better answer than "use 1.7.2 or upgrade"

Got it, take a look at guide https://github.com/coverlet-coverage/coverlet/blob/master/Documentation/GlobalTool.md

You don't need to reference the tool in your project it runs standalone.

Thanks Marco, that's a big help.
