Proposal: Add Targets for Other .NET Runtimes Explicitly about high-speed-priority-queue-for-c-sharp HOT 2 OPEN

I have no formal documentation that states it specifically; just some experience with other projects where it appeared that there was some speed increase when the version of .NET being targeted was more specific. C# syntax is not entirely backwards compatible across multiple run-times (at least since the introduction of C# 8; there are features in C# 8 you cannot use when you target versions of runtimes prior to when it was introduced); so it is conceivable that the IL of the compiled library would change for different targets; so it is possible it could be optimized differently. Certainly it's something I recommend you benchmark for yourself for this particular case, if you attempt it at all.

Regardless, (and this may be better as a separate proposal, up to you); I do think it would be ideal if you targeted both .NET standard 2.0 and .NET Standard 1.0 explicitly, even if no other frameworks are targeted. The Microsoft guidance specifically recommends that you have an explicit .NET Standard 2.0 target in order to avoid bloating package graph when you must also target .NET Standard 1.x:

✔️ DO include a netstandard2.0 target if you require a netstandard1.x target.
All platforms supporting .NET Standard 2.0 will use the netstandard2.0 target and benefit from having a smaller package > graph while older platforms will still work and fall back to using the netstandard1.x target.

targeting the runtimes specifically can, under some circumstances, enable the compiler to apply optimizations that only work for the particular version of .NET being targeted

Do you have a source for this? The C# compiler itself does almost no optimizations - nearly all of them are done by the JIT. It would be very surprising if the JIT were holding back optimizations simply because the code was compiled using an older version of .Net Standard.
