Those of you who have been following .NET development closely have very likely seen Scott Hunter’s latest blog post, .NET Core is the Future of .NET.
The first preview of the EF 6.3 runtime is now available in NuGet.
Note that the package is versioned as 6.3.0-preview5. We plan to continue releasing previews of EF 6.3 every month in alignment with the .NET Core 3.0 previews, until we ship the final version.
In .NET Core 3.0, we are introducing a suite of tools that utilize new features in the .NET runtime that make it easier to diagnose and solve performance problems.
These runtime features help you answer some common diagnostic questions you may have:

We introduced .NET Core 1.0 on November 2014. The goal with .NET Core was to take the learning from our experience building, shipping and servicing .NET Framework over the previous 12 years and build a better product. Some examples of these improvements are side-by-side installations (you can install a new version and not worry about breaking existing apps),

Earlier this year, I wrote about an update to the roadmap for F# and .NET Core. I had mentioned that there were a number of things you could build with F# and .NET Core today, such as web services. In this post,
Get Started with F# as a C# developer
One of our previous posts, Why You Should Use F#, listed a few reasons why F# is worth trying out today. In this post, we’ll cover some of the basics you need to know to be successful.

Your friendly neighborhood .NET productivity team (aka. Roslyn) focuses a lot on improving the .NET coding experience. Sometimes it’s the little refactorings and code fixes that really improve your workflow. You may have seen many improvements in the previews, but for all of you who were eagerly awaiting the GA release here’s a few features you may enjoy!
Starting with Visual Studio 2019 Preview 4, we'll be adjusting how C# versions are treated in .NET tooling. Firstly, we're adding two new Language Version (LangVersion) values: LatestMajor and Preview. Rad the post to see how they stack up with the currently supported list of values.
Take C# 8.0 for a spin
Yesterday we announced the first preview of both Visual Studio 2019 (Making every developer more productive with Visual Studio 2019) and .NET Core 3.0 (Announcing .NET Core 3 Preview 1 and Open Sourcing Windows Desktop Frameworks).
Building C# 8.0
The next major version of C# is C# 8.0. It’s been in the works for quite some time, even as we built and shipped the minor releases C# 7.1, 7.2 and 7.3, and I’m quite excited about the new capabilities it will bring.

Entity Framework
The first preview of the EF 6.3 runtime is now available in NuGet.
Note that the package is versioned as 6.3.0-preview5. We plan to continue releasing previews of EF 6.3 every month in alignment with the .NET Core 3.0 previews, until we ship the final version.
Today, we are making the fourth preview of Entity Framework Core 3.0 available on NuGet, alongside .NET Core 3.0 Preview 4 and ASP.NET Core 3.0 Preview 4. We encourage you to install this preview to test the new functionality and assess the impact of the included breaking changes.
Today we’re making the final version of EF Core 2.2 available, alongside ASP.NET Core 2.2 and .NET Core 2.2. This is the latest release of our open-source and cross-platform object-database mapping technology.
EF Core 2.2 RTM includes more than a hundred bug fixes and a few new features:
Spatial data support
Spatial data can be used to represent the physical location and shape of objects.
Entity Framework Core 2.2 Preview 3 available with a new preview of our data provider for Cosmos DB and updated spatial extensions for various providers. Preview 3 is going to be the last milestone before EF Core 2.2 RTM, so now is your last chance to try the bits and give us feedback if you want to have an impact on the quality and the shape of the APIs in this release.
Today we are making EF Core 2.2 Preview 2 available, together with a preview of our data provider for Cosmos DB and new spatial extensions for our SQL Server and in-memory providers.
Obtaining the preview
The preview bits are available on NuGet,
Today we are excited to announce the release of Entity Framework (EF) Core 2.1. This is the latest production-ready release of our open-source and cross-platform data access technology. We are releasing today alongside .NET Core 2.1 and ASP.NET Core 2.1. EF Core 2.1 targets .NET Standard 2.0 and so also runs on .NET Core 2.0 and .NET Framework 4.6.1 or later.
Today, we are excited to announce that the first release candidate of EF Core 2.1 is available, alongside .NET Core 2.1 RC 1 and ASP.NET Core 2.1 RC 1, for broad testing, and now also for production use!

F# 4.6 is now fully released. See the announcement blog post for more.
We’re excited to announce that Visual Studio 2019 will ship a new version of F# when it releases: F# 4.6!
F# 4.6 is a smaller update to the F# language,
Today, we’re incredibly pleased to announce general availability of F# 4.5.
This post will walk through the changes in F# 4.5 (just like the preview post), then show some updates to F# tooling, and finally talk a bit about where what we’re thinking about for the next F# version.
Accounting for this change on Windows build servers: You may be doing one of the following things to install F# on a Windows build server. 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.
We’re excited to share updates about changes to F# and F# tools which shipped with the Visual Studio 2017 version 15.7 release. Let’s dive in!
Type Providers now support .NET Standard
For those who aren’t familiar with Type Providers, they are a feature of F# which allow you to get IntelliSense for data.

A customer who just experienced some server outage asked us for help as they thought it was due to some very long GC pauses. I thought this diagnostics exercise might be useful for other folks as well so I am sharing it with you.
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.
End of last year I mentioned we wanted to provide an API for you to really investigate GC/managed memory related performance called GLAD. Well, the source finally got opened source on github. 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).
