Backport of #91290 to release/8.0

/cc @steveharter

Customer Impact

Customers using DependencyInjection may see a significant performance regression (2-4x) to the ActivatorUtilities.CreateInstance() API and other APIs which call it. This regression was introduced with the "keyed services" feature that added in Preview 7 due to reading attributes on members.

9.0 PR: #91290
Perf issue: #91186

Testing

The existing tests are fairly thorough, but the fix added a cache that supports unloadable assemblies, so a new test was added for that. Note that assembly unloading is not supported on Mono or NativeAOT.

Risk

Low - the new cache is fairly straightforward, caching reflection-based metadata based on System.Type. Assembly unload-ability and Visual Studio hot reload have been accounted for.

Backport of #91290 to release/8.0
/cc @steveharter
Customer Impact
Customers using DependencyInjection may see a significant performance regression (2-4x) to the ActivatorUtilities.CreateInstance() API and other APIs which call it. This regression was introduced with the "keyed services" feature that added in Preview 7 due to reading attributes on members.
9.0 PR: #91290

Perf issue: #91186
Testing
The existing tests are fairly thorough, but the fix added a cache that supports unloadable assemblies, so a new test was added for that. Note that assembly unloading is not supported on Mono or NativeAOT.
Risk
Low - the new cache is fairly straightforward, caching reflection-based metadata based on System.Type. Assembly unload-ability and Visual Studio hot reload have been accounted for.
