At work, we are planning to migrate our WPF application from .NET Framework 4.7 to .NET Core 3.0. The main reason for doing so is that it was always a big pain to organize the updates of the .NET Framework on our customer machines. So being able to bundle .NET Core with our application is a big plus for us. Then, for sure, we are looking for the performance improvements brought by .NET Core and finally the new capabilities brought by the fast pace of innovation of .NET Core. 

These are the customer-reported issues addressed in 15.8.5:

• Debugger tooltip does not expand in Xamarin.iOS debugging session.
• Debugger won't let me leave execution point (Android).
• After updating to 15.8.1, data tip does not show when debugging.
• Debugger data tip does not expand [Editor].
• Exception:MSB0001: Internal MSBuild Error: Already registered for build-time.
• Wrong path to resource in manifest for ClickOnce after upgrading to VS 15.8.1.
• ClickOnce Manifest error in 15.8.
• ClickOnce Publish is missing certain references.
• ClickOnce: Language file copied to wrong location.
• Reference missing in the ClickOnce publish folder.
• Compiling non-.NET SDK style F# projects results in an internal MSBuild error unless MSBuild parallelism is set to 1.
• F# is not NGEN'd in Visual Studio.
• F# deploys the FSharp.Core 4.5.0.0 binary in the 4.4.3.0 location.

Visual Studio Tools for Xamarin

Visual Studio Tools for Xamarin now supports Xcode 10, which allows you to build and debug apps for iOS 12, tvOS 12, and watchOS 5. See how to get ready for iOS 12 and our introduction to iOS 12 for more details on the new features available. 

You can download .NET 6 Preview 1, for Windows, macOS, and Linux.

• Installers and binaries
• Container images
• Linux packages
• Release notes
• Known issues
• GitHub issue tracker

.NET 6 has been tested with Visual Studio 16.9 Preview 4 and Visual Studio for Mac 8.9. We recommend you use those builds if you want to try .NET 6. 

• Support for .NET Core 2.0: you can now edit, run, debug, test, navigate and refactor your shiny new .NET Core applications.
  
• Rider 2017.2 comes with ReSharper 2017.2 as its engine for providing .NET support. This means a number of features announced with ReSharper 2017.2 are now available in Rider. 

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. 

Today we are releasing the final version of Entity Framework Core 2.0, alongside .NET Core 2.0 and ASP.NET Core 2.0.

Entity Framework (EF) Core is the lightweight, extensible, and cross-platform version of Entity Framework, the popular Object/Relational Mapping (O/RM) framework for .NET. 

Today, we’re releasing .NET 5.0 Preview 6. It contains a small set of new features and performance improvements. The .NET 5.0 Preview 4 post covers what we are planning to deliver with .NET 5.0. Most of the features are now in the product, but some are not yet in their final state. We expect that the release will be feature-complete with Preview 8. 

The next stop for .NET 7 is General Availability, one month out, as Microsoft today shipped .NET 7 Release Candidate 2.
