- Prior to this change we'd hit the disk every time we'd create a `TagHelperDesignTimeDescriptor` to locate an assemblies XML files.
- Did not want to tie the XML cache to a static member in-case a user updates their XML information between parses. Therefore, changed `TagHelperDescriptorFactory` and `TagHelperDesignTimeDescriptorFactory` to no longer be static.
- Put the same `TagHeleprDescriptorFactory` extensibility point as we had for its counterpart `TagHelperTypeResolver` to stay consistent. This involved making `CreateDescriptors` virtual and allowing it to be provided in the `TagHelperDescriptorResolver` constructor.
#630
- Could not add tests to validate the full TagHelperDescriptorFactory.CreateDescriptors => TagHelperUsageDescriptors due to how the runtime loads assemblies (does it in memory without XML).
- Added serialization tests to include TagHelperUsageDescriptors.
- Updated existing tests to use new TagHelperDescriptor/TagHelperAttributeDescriptor constructors.
#352
- Used to only look at declared properties on the tag helper type, now we get the runtime properties.
- Fixed Runtime test projec to work with new CLR changes (looks like it was missed).
