Mismatch between supported RIDs and the expected RID parameter

[dickymoore]

The RID catalogue lists linux-musl-x64 as an option when specifying architecture.

Yet when running
dotnet publish app.csproj -c Release -o appfolder -a linux-musl-x64

I receive the error:

error NETSDK1083: The specified RuntimeIdentifier 'linux-linux-musl-x64' is not recognized.

It looks like something is prepending linux- to the architecture RID I'm putting in. I've had this on versions 6.0.100 and 6.0.302.

Changing the parameter to remove the first section, like this:
dotnet publish app.csproj -c Release -o appfolder -a musl-x64

seems to resolve the issue.

Either the documentation is incorrect, or the name of the architecture is incorrect, or I'm missing something in my understanding of how this should fit together.

Hi @dickymoore - the two new shorthand options for specifying a RID (--arch and --os) are meant to specify one half of a complete RID. You can read more about this here, but in general if you specify one half of a complete RID using these flags, the other half is inferred from your current SDK runtime environment. That's where the linux portion you're seeing inserted is coming from.
