What do the "projects", "sdk/runtime" and "sdk/architecture" keys mean?

[martingbrown]

I've seen a few global.json files that look like this:

{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-beta5",
"runtime": "clr",
"architecture": "x86"
}
}

What do the "projects", "sdk/runtime" and "sdk/architecture" keys mean? If they are obsolete it would be handy if this page said so.

They no longer carry any meaning. They were used during preview tooling (and before that: DNX tooling).

What's also in global.json but not in this doc is msbuild SDKs - https://github.com/MicrosoftDocs/visualstudio-docs/blob/master/docs/msbuild/how-to-use-project-sdk.md

As @dasMulli pointed out, this is the old schema and I don't think we should document the preview schema. I'm including a link to that topic on my PR that updates the global.json topic: #4704
