Phillip CarterJuly 26, 2018Jul 26, 201807/26/18

Installing the full Visual Studio IDE Installing the F# Compiler SDK MSI Neither of these options have been recommended for some time, but are still available with F# 4.1. For using F# 4.5 in a Windows build server, we recommend (in order of preference), Using the .NET SDK, the FSharp.Compiler.Tools package, or the Visual Studio Build Tools SKU.
Better async stack traces Starting with F# 4.5 and FSharp.Core 4.5.0, stack traces for async computation expressions: Reported line numbers now correspond to the failing user code Non-user code is no longer emitted For example, consider the following DSL and its usage with an FSharp.Core version prior to 4.5.0: Note that both the f1 and f2 functions are called twice.

Hardware Intrinsics in .NET Core

Tanner Gooding [MSFT]September 3, 2019Sep 3, 201909/3/19

Several years ago, we decided that it was time to support SIMD code in .NET. We introduced the System.Numerics namespace with Vector2, Vector3, Vector4, Vector<T>, and related types. These types expose a general-purpose API for creating, accessing, and operating on them using hardware vector instructions (when available).

You Should Never See This Callstack in Production

Middle Ground between Server and Workstation GC

maoniOctober 2, 2018Oct 2, 201810/2/18

A long time ago I wrote about using Workstation GC on server applications when you have many instances of your server app running on the same machine. By default Server GC will treat the process as owning the machine so it uses all CPUs to do the GC work.

GLAD is available

So GLAD is available. The repo is called PerfView but you actually just need the TraceEvent project (but it’s much easier to just build the whole solution then add the reference to the resulting Microsoft.Diagnostics.Tracing.TraceEvent.dll).
