LinqBenchmarks

Benchmarks comparing the performance of LINQ against for/foreach loops and the following libraries:

Faslinq
Cistern.ValueLinq
JM.LinqFaster
LinqFasterer
LinqAF
SpanLinq
StructLinq
NetFabric.Hyperlinq
System.Linq.Async
 

Blazor is full of promise, and Matthew MacDonald penned this succinct analysis of Blazor Desktop, comparing it to Electron (a JavaScript wrapper for desktop apps) for .NET. 

This post will be comparing the performance of RyuJIT in .NET Framework 4.6.2 to its performance in .NET Core 2.0 and .NET Framework 4.7.1.
