Description

The System.Runtime.Loader.AssemblyLoadContext.MonoResolveUnmanagedDllUsingEvent method is linked away when it's still needed, resulting in an assertion at runtime:

error: * Assertion at /Users/runner/work/1/s/src/mono/mono/metadata/native-library.c:708, condition `resolve' not met

Crash report: link sdk_2021-01-12-235327_XAMBOT-1105-20210112_235328.crash.txt

Standard output: stdout-20210112_235311.log

The workaround is to preserve the method that is linked away: rolfbjarne/xamarin-macios@ece7188

My guess is that this is a regression caused by #46323.

This is with .NET 6.0.100-alpha.1.21060.3 (from yesterday).

Bump to .NET 6.0.100-alpha.1.21060.3. (#10388)
7584ada 
* Bump to .NET 6.0.100-alpha.1.21060.3.

* Fix dotnet command line arguments.

* dotnet build: the project file must be the first argument.
* dotnet build/publish: use the documented verbosity format.

* Update version number in tests.

* [tests/introspection] Adjust introspection to cope with different library names in the new .NET version.

* [tests/link sdk] Adjust the LinkSdkRegressionTest.SpecialFolder test according to the new version of .NET 6.

* [tests/link sdk] Preserve a required method in System.Private.CoreLib to work around a bug in .NET 6.

Ref: dotnet/runtime#46908.

* Revert "[CI][VSTS] Add the donet 6 pkg as a dependency. (#10348)"

This reverts commit 6de4e71.

There's no need to provision .NET 6, it's done automatically.
