X-Platform Building Broken - R2R

[rbaker26]

X-Platform Building does not work. Seems to be a problem with Ready2Run (R2R).
This problem occurred for me after updating to 9.31.2.
For debugging, I tired the following test of both My Project and the Demo Project

• Version: 9.31.2.0

• .NET Core: 3.1.301

• Target: See Table

Before 9.31.2

Build Platform	Target Win	Target Linux	Target OSX
Windows	✔️	✔️	❌ *
Linux	✔️	✔️	✔️
OSX	❔	❔	❔

* Windows to OSX was never supported due to symlinks

As of 9.31.2

Build Platform	Target Win	Target Linux	Target OSX
Windows	✔️	❌	❌ *
Linux	❌	✔️	❌
OSX	❔	❔	❔

* Windows to OSX was never supported due to symlinks

Now when building cross-platform targets, I get the following message:

error NETSDK1095: Optimizing assemblies for performance is not supported for the selected target platform or architecture. Please verify you are using a supported runtime identifier, or set the PublishReadyToRun property to false.

Note: I will include the full error messages for the different platforms below.

According to docs.microsoft.com,

The ReadyToRun compiler doesn't currently support cross-targeting. You must compile on a given target. For example, if you want R2R images for Windows x64, you need to run the publish command on that environment.

Before updating to 9.31.2, I was able to build targets for other systems.

Build Platform	Target Win	Target Linux	Target OSX
Windows	✔️	win-to-linux-r2r.txt	❌ *
Linux	linux-to-win-r2r.txt	✔️	linux-to-osx-r2r.txt
OSX	❔	❔	❔

* Windows to OSX was never supported due to symlinks

Turning off R2R

To turn off R2R, the /PublishReadyToRun flag was set to false:

rbaker@DESKTOP-EUK8SOJ:***/ElectronNET-API-Demos$ electronize build /target win /PublishReadyToRun false

This caused a new set of errors:

Build Platform	Target Win	Target Linux	Target OSX
Windows	✔️	win-to-linux.txt	❌ *
Linux	linux-to-win.txt	✔️	linux-to-osx.txt
OSX	❔	❔	❔

Summery

I don't have access to an OSX box, so I cannot test that aspect. Maybe someone here can?

I don't know what to make of these error messages. I will continue to try to decipher them, but there is a lot of "terminal vomit" involved with this.

Fixed in the new version from Electron.NET 9.31.3.

@GregorBiswanger i've same issue, but only 9.31.2 available on nuget. Can you say when 9.31.3 will be publish?
