Terminal Logger hides warning code `NETSDK1057` from message `You are using a preview version of .NET...`

[Frulfump]

Issue Description

I want to see the code so I can search for it or disable it etc.

The message when turning of the Terminal Logger -tl:off Includes the target and project which is also beneficial to see.
C:\Program Files\dotnet\sdk\10.0.100-preview.5.25277.114\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.RuntimeIdentifierInference.targets(326,5): message NETSDK105
7: You are using a preview version of .NET. See: https://aka.ms/dotnet-support-policy [<project-name>.csproj]

Steps to Reproduce

Run dotnet build using .NET 10 SDK 10.0.100-preview.5.25277.114 (pretty sure this was the same for .NET 8 and 9 when they were in preview)

Expected Behavior

The warning code is included in the message

Actual Behavior

Only this message is shown You are using a preview version of .NET. See: https://aka.ms/dotnet-support-policy

This is a bit of a 'by design' thing, but I can see where it would be frustrating if you're used to being able to see MSBuild message codes of all kinds and filtering them out.

Another thing that's annoying here is that MSBuild doesn't really allow for the suppression of message codes like it does with warnings and errors. That's a larger unit of work. The .NET SDK could and should add a bit of logic to see if you've got NETSDK1057 in your NoWarns at all and automatically suppress that specific message for you though. I've just opened dotnet/sdk#49599 to handle that piece.

Ah that's good info. Thanks for the issues and PRs! What's the canonical way to suppress that before the PR is merged? Edit: I found it <SuppressNETCoreSdkPreviewMessage>true</SuppressNETCoreSdkPreviewMessage> but couldn't find obvious Microsoft docs for that property when searching for the message code. An environment variable exists as well https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-environment-variables#suppressnetcoresdkpreviewmessage

Maybe the URL in the message should point to some more specific docs instead of the support policy (or both I guess?) as is the case now (in the past it used to point to https://aka.ms/dotnet-core-preview)

This is what I see on my machine:

$ dotnet build
Restore complete (0.2s)
You are using a preview version of .NET. See: https://aka.ms/dotnet-support-policy
  DotnetRelease succeeded (1.3s) → /home/rich/git/distroessed/src/DotnetRelease/bin/Debug/net8.0/DotnetRelease.dll
  UpdateReleasesIndex succeeded (0.4s) → bin/Debug/net10.0/UpdateReleasesIndex.dll

Like others, I'm not a fan of the preview message, particularly when it appears multiple times. I'd be much happier if the first first line was something like ".NET CLI 10.0.100-preview.5.25277.114". That would remove the annoying message and make it easier to communicate .NET versions in issues. The preview aspect would still be present and would only ever show up once.

Like this:

$ dotnet build
.NET CLI 10.0.100-preview.5.25277.114
Restore complete (0.2s)
  DotnetRelease succeeded (1.3s) → /home/rich/git/distroessed/src/DotnetRelease/bin/Debug/net8.0/DotnetRelease.dll
  UpdateReleasesIndex succeeded (0.4s) → bin/Debug/net10.0/UpdateReleasesIndex.dll
