Backport of #76665 to release/6.0

/cc @lambdageek@uweigand

Customer Impact

When customer code is compiled against older assemblies, but newer versions are available at runtime, certain combinations of old vs new versions wlll be compared incorrectly and the runtime will refuse to load the newer assembly believing it to be older than the older assembly.

This affects all platforms that use Mono as the execution engine (iOS, Android, WebAssembly, s390x Linux).

Testing

Manual testing

Risk

Low. The underlying issue is an incorrect order of comparison of the 3rd and 4th component of an assembly version. In many cases the 4th component is 0, so it doesn't matter if it's compared before or after the 3rd component since it doesn't affect the final result.

* Compare version components in the correct order in
assembly_names_compare_versions
* Fixes#76664

Backport of #76665 to release/6.0

/cc @lambdageek@uweigand

Customer Impact

When customer code is compiled against older assemblies, but newer versions are available at runtime, certain combinations of old vs new versions wlll be compared incorrectly and the runtime will refuse to load the newer assembly believing it to be older than the older assembly.

This affects all platforms that use Mono as the execution engine (iOS, Android, WebAssembly, s390x Linux).

Testing

Manual testing

Risk

Low. The underlying issue is an incorrect order of comparison of the 3rd and 4th component of an assembly version. In many cases the 4th component is 0, so it doesn't matter if it's compared before or after the 3rd component since it doesn't affect the final result.

* Compare version components in the correct order in
assembly_names_compare_versions
* Fixes#76664
