Branch arcade for .NET 5.

[lukas-lansky]

We should merge https://github.com/dotnet/arcade/pull/6274 before proceeding. Also, @epananth, do you happen to know whether the channel creation docs as discussed in the e-mail are up-to-date? Thanks!

[epananth]

This is the channel creation doc-> https://github.com/dotnet/arcade/blob/master/Documentation/Darc.md#add-channel

@mmitche - should I add a link to this from Publishing.md? Or is there something else that I need to add here?

[lukas-lansky]

I will start now.

@epananth We should make sure we have details on how to add new channels into the publishing infrastructure too

[lukas-lansky]

@mmitche Should this file be updated with the new channel names (.NET 5 Eng[...]) and IDs given it already contains .NET 3 Eng[...]?

[mmitche]

@lukas-lansky Nope. That's for v2 publishing, which arcade doesn't need any longer. But we do need to add entries for publishing .NET 5 in PublishingConstants.cs, as seen for .NET Eng - Latest here:

https://github.com/dotnet/arcade/blob/master/src/Microsoft.DotNet.Build.Tasks.Feed/src/model/PublishingConstants.cs#L240-L260

I think you'll want:

• The Feed* parameters can be the same,
• PublishingInfraVersion.Next,
• akaMSChannelName: eng/net5 and eng/net5validation

[lukas-lansky]

@mmitche Thanks! (For documentation reasons:) Is it something that should be done before branching so both master and release/5.0 contains the definition?

[mmitche]

Just master needs it (master is the branch publishing is run off of right now)

[lukas-lansky]

"Reset arcade Maestro++ subscriptions targeting .NET release branches to source from .NET Eng."

This is about sourcing from .NET Eng 5 instead of .NET Eng for .NET 5 branches, right? @mmitche

[mmitche]

Yep!

[lukas-lansky]

So, I updated subscriptions targeting release/5.0/release/5.0.1xx to channel .NET 5 Eng. According to the list, this should be done. Please let me know @mmitche how to verify or whether you see something I should fix.

(I know we need to merge #6360 as soon as it finishes.)

[lukas-lansky]

Everything seems fine to me. I obviously don't want to trigger the flow and rebuild all the .NET 5 release branches to verify completely. So still not completely sure.

@riarenas @ChadNedzlek Please let me know if you notice a problem that might be connected to this effort. Thanks!

[riarenas]

I took a look yesterday and thinks looked right. The default channels, branch changes, and subscriptions looked correct to me, but we'll know for sure the first time this needs to run.

Thanks @lukas-lansky

[riarenas]

Looks like we missed the subscription from arcade to arcade-validation for the new branch. I just created it
