YairHalberstadt and stephentoub Always use ElementAtOrDefault in ElementAtOrDefaultTests (#33578) 
It looks like ElementAtOrDefaultTests were copied from ElementAtTests, and not all the usages of ElementAt were changed to ElementAtOrDefault. This commit fixes that.

.NET Core Libraries (CoreFX)

This repo contains the library implementation (called "CoreFX") for .NET Core. It includes System.Collections, System.IO, System.Xml, and many other components. The corresponding .NET Core Runtime repo (called "CoreCLR") contains the runtime implementation for .NET Core. It includes RyuJIT, the .NET GC, and many other components. Runtime-specific library code (mscorlib) lives in the CoreCLR repo. It needs to be built and versioned in tandem with the runtime. The rest of CoreFX is agnostic of runtime-implementation and can be run on any compatible .NET runtime (e.g. CoreRT).

How to Engage, Contribute and Provide Feedback

Some of the best ways to contribute are to try things out, file bugs, join in design conversations, and fix issues.

If you are having issues with the "full" .NET Framework (also called "Desktop"), the best way to file a bug is the Report a Problem tool, which is integrated with the VS Developer Community Portal; or through Product Support if you have a contract.
