Epic: Make sure .NET libraries are continuously improved

[terrajobst]

Summary

We'll use this epic to collect bottom-up improvements coming from the engineering team.

Dev features/work:

• Developers can use a built in PriorityQueue type #43957
• Developers using FileStream find it to be high performance and robust #40359
• Developers can benefit from enhanced Date and Time types and Timezone support #45318
• Developers can use Compression in WebSocket #20004
• Developers get high-performant HTTP stack #46850
• Developers can control TLS establishment in SocketsHttpHandler via a callback #46849
• Developers using Kestrel can configure the list of CAs per-hostname #45456
• Runtime developer can run Networking tests without Loopback server capability (on mobile/browser platforms) #42852
• Developers have their top System.Linq feature requests implemented #47231
• Developers can have access to more options when configuring async awaitables #47525
• Developers using filesystem APIs find them to work well with symbolic links #51605
• Developers can get immediate feedback on validation problems #36391
• Enhance user-facing API for strongly-typed ILogger messages #36022
• Developers can use CollectionsMarshal ref accessors for Dictionary<TKey, TValue> #27062

These issues were not completed in .NET 6

• Developers can access documentation for all .NET Core/.NET 5 APIs #43849
• Built-in configuration providers can do more robust key handling #44517
• Enhancement to IDistributedCache - Allow for bulk remove and key enumeration #44512
• Libraries APIs are fully documented using efficient workflows #44969
• Developers can enumerate directories and files using globbing patterns #21362
• Developers using Reflection should be able to use pointers and function pointers #44327
• System.Reflection work planned for .NET 7 #44655
• Developers using Console can employ VT/ANSI APIs (eg to use embedded color codes) #44513
• Developers can create scopes to support load/unload scenarios because AssemblyLoadContext is supported throughout .NET  #43544

@terrajobst it feels like the documentation debt issue could be added as a user story in the description:
#43849

Agree? Or should it be somewhere else / have its own epic?

[danmoseley]

@carlossanlop yup, you can add a checkbox for it above then it will link up in https://dotnetepics.azurewebsites.net/

[marek-safar]

I think this issue should be moved to dotnet/runtime

[Dotnet-GitSync-Bot]

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

[danmoseley]

We'll be adding more proposed stories to the list above.

I'll use this opportunity to bring these "grassroots" issues to attention:

• Add Enumerable.*By operators (DistinctBy, ExceptBy, IntersectBy, UnionBy, MinBy, MaxBy) Add Enumerable.*By operators (DistinctBy, ExceptBy, IntersectBy, UnionBy, MinBy, MaxBy) #27687
• Add common helper methods to the String class (Contains(StringComparison), Replace(StringComparison), Left, Truncate, TrimPrefix) Add common helper methods to the String class (Contains(StringComparison), Replace(StringComparison), Left, Truncate, TrimPrefix) #14831
• New API: String.Truncate(int maxLength, string truncationSuffix) New API: String.Truncate(int maxLength, string truncationSuffix) #31655

Some of these would inspire joy and love in the community.
