Starting in .NET 5.0, these analyzers are included with the .NET SDK. Code analysis is enabled, by default, for projects that target .NET 5.0 or later. You can enable code analysis on projects that target earlier .NET versions by setting the EnableNETAnalyzers property to true. You can disable code analysis for your project by setting EnableNETAnalyzers to false. You can also use the Project Properties window to enable/disable .NET analyzers. To access the Project Properties window right-click on a project within Solution Explorer and select Properties. Next, select the Code Analysis tab where you can either select or clear the checkbox to Enable .NET analyzers.

Debugger
.NET Core Linux core dump debugging support
Debugging managed Linux core dumps on Windows has been difficult realize until now, it would usually mean setting up another Linux environment that exactly mirrored production and then installing a set of tools for the analysis. Thankfully with Visual Studio 2019 16.8 preview 3 you can simply drag and drop a managed Linux core dump directly into your IDE and immediately start debugging.
.NET and .NET Core Auto Analysis
![Xcode Xcode](https://pbs.twimg.com/media/EkUL_yRUwAAtJTr.png)
Asynchronous (async) programming has been around for several years on the .NET platform but has historically been difficult to do well. We have introduced and managed memory dump analyzer that helps identify the follwoing ant-patterns:
- Sync-over-Async
- Async Void
.NET and .NET Core memory hot path auto analysis
This allows customers to intuitively view the dominating object types in their memory heap by using flame annotations in the Diagnositcs Memory Tool window.
XAML Tools (WPF, UWP & Xamarin.Forms)
XAML Hot Reload Settings moved to 'Debugging > Hot Reload': In this release we have completed the XAML Hot Reload settings migration for Xamarin.Forms to the new location under 'Debugging > Hot Reload'. This means customers who previously found the Xamarin.Forms XAML Hot Reload settings under 'Xamarin > Hot Reload' will now find them in the new dialog as shown below. All settings have been migrated so all of your existing selections should still match what they were in the previous location.
XAML Hot Reload Consolidated SettingsToolbox population from unreferenced NuGet packages: In this release we have added support for TargetFrameworkMoniker-specific VisualStudioToolsManifest.xml files when populating Toolbox with controls from unreferenced NuGet packages. So, for example, your package could expose different sets of controls to .NET Core 3.1 and .NET 5.0 projects.
Improving MVVM Support: When authoring a XAML document, you can set d:DataContext to get accurate binding IntelliSense for the XAML document. In the past, manually specifying the /> to an ItemGroup in your csproj file.

XAML Tools (WPF, UWP & Xamarin.Forms)
XAML Hot Reload Settings moved to 'Debugging > Hot Reload' – as part of a bigger effort that will be completed across multiple 16.8 Preview release, we're starting to consolidate the XAML Hot Reload settings across WPF, UWP and eventually Xamarin.Forms into a unified settings location. In this release we've started this process by moving the existing desktop settings out of the 'Debugging > General > Enable UI Debugging Tools for XAML' and into a new location under 'Debugging > Hot Reload'. No settings will be changed during this migration so all your existing choices will continue to stay in effect. Also, for the first time ever we're enabling the ability to disable/enable XAML Hot Reload support per-platform, meaning you can disable these experiences for WPF, UWP or both.
Xamarin.Forms 'changes only' XAML Hot Reload now supports UWP – in this release we begin to rollout support for a highly requested feature that enables the new changes only XAML Hot Reload support in Xamarin.Forms Projects when targeting UWP. Please note this feature is still in development, and while editing XAML will now trigger updates in the running app other features such as in-app toolbar (element selection, etc.) are not yet fully implemented and can have unpredictable behavior.

XAML Tools (WPF, UWP & Xamarin.Forms)
XAML Designer Suggested Actions enables easy access to common properties when a control is selected within the XAML Designer. To use this feature first enable it through Options > Preview Features > XAML Suggested Actions. Once enabled click on a supported control and use the lightbulb to expand and interact with the Suggestion Actions UI. In this release supported controls include:
- For UWP: Border, Button, Canvas, CheckBox, ComboBox, Grid, HyperlinkButton, Image, ListBox, ListView, NavigationView, RadioButton, Slider, StackPanel, TextBlock
- For WPF: Border, Button, Canvas, CheckBox, ComboBox, Grid, Image, Label, ListBox, ListView, StackPanel, TextBlock, TextBox.
This feature is available for UWP, WPF .NET Core and WPF .NET Framework (with enabled 'New WPF XAML Designer for .NET Framework' feature flag) applications and doesn't support extensibility, nor is it feature complete.
XAML Designer: Suggested Actions- XAML Suggested Actions - Extensibility: We've also recently introduced extensibility for 'Suggested Actions'. Now you will be able to customize and build your own suggestion dialog for your controls. For more details see our documentation in GitHub
The New WPF XAML Designer for .NET Framework Projects is now available for early preview. This brings the same designer and extensibility support available for WPF .NET Core developers to WPF .NET Framework. Benefits of this improved XAML designer includes faster load performance, 64-bit configuration support (custom controls would load normally just like they do in x86 configuration), improved stability and new features such as Suggested Actions.
To get started, go to Options > Preview Features, select 'New WPF XAML Designer for .NET Framework' and restart Visual Studio. This feature is only available in the Preview channel for early testing; its final release details have not yet been determined. We encourage all WPF .NET Framework customers to give this designer a try and report any issues you encounter through the VS Feedback Hub.
XAML Binding Failures diagnostic improvements
In this release we continue to test a new features that makes becoming aware of and seeing the details of XAML binding failures easier, these improvements include:
- New XAML Binding failure indicator icon in the in-app toolbar experience for WPF and UWP developers. This icon will change red if at least one binding fails and highlighting it will show you the total number of failed bindings in the tooltip. Clicking the icon will take you to the new XAML Binding Failures panel
- New XAML Binding Failures panel that takes the binding failures that were previously only available in the Output window and makes them easy to review in the new dedicated experience with features such as sorting, searching and grouping of similar errors. This panel works for WPF, UWP and Xamarin.Forms projects (note: requires Xamarin version 4.5.0.266-pre3 or higher)
This feature is still in development and is only available if enabled by customers. To enable this experience, go to Options > Environment > Preview Features and enable 'XAML Binding Failure Window'.
Known Limitations: Clicking on binding failures in the panel does not yet navigate to code. Also attaching to a running process will not work, you must F5 into the debug experience for this experience.
Editor
- In this release, the legacy Find in Files experience has been deprecated and all users are being moved to the new experience. The Editor team is working with folks who leave feedback in Developer Community who are experiencing issues with the modern Find in Files experience.

Once enabled click on a supported control and use the lightbulb to expand and interact with the Suggestion Actions UI. In this release supported controls include:
- For UWP: Border, Button, Canvas, CheckBox, ComboBox, Grid, HyperlinkButton, Image, ListBox, ListView, NavigationView, RadioButton, Slider, StackPanel, TextBlock
- For WPF: Border, Button, Canvas, CheckBox, ComboBox, Grid, Image, Label, ListBox, ListView, StackPanel, TextBlock, TextBox.
This feature is available for UWP, WPF .NET Core and WPF .NET Framework (with enabled 'New WPF XAML Designer for .NET Framework' feature flag) applications and doesn't support extensibility, nor is it feature complete.
XAML Designer: Suggested Actions- XAML Suggested Actions - Extensibility: We've also recently introduced extensibility for 'Suggested Actions'. Now you will be able to customize and build your own suggestion dialog for your controls. For more details see our documentation in GitHub
The New WPF XAML Designer for .NET Framework Projects is now available for early preview. This brings the same designer and extensibility support available for WPF .NET Core developers to WPF .NET Framework. Benefits of this improved XAML designer includes faster load performance, 64-bit configuration support (custom controls would load normally just like they do in x86 configuration), improved stability and new features such as Suggested Actions.
To get started, go to Options > Preview Features, select 'New WPF XAML Designer for .NET Framework' and restart Visual Studio. This feature is only available in the Preview channel for early testing; its final release details have not yet been determined. We encourage all WPF .NET Framework customers to give this designer a try and report any issues you encounter through the VS Feedback Hub.
XAML Binding Failures diagnostic improvements
In this release we continue to test a new features that makes becoming aware of and seeing the details of XAML binding failures easier, these improvements include:
- New XAML Binding failure indicator icon in the in-app toolbar experience for WPF and UWP developers. This icon will change red if at least one binding fails and highlighting it will show you the total number of failed bindings in the tooltip. Clicking the icon will take you to the new XAML Binding Failures panel
- New XAML Binding Failures panel that takes the binding failures that were previously only available in the Output window and makes them easy to review in the new dedicated experience with features such as sorting, searching and grouping of similar errors. This panel works for WPF, UWP and Xamarin.Forms projects (note: requires Xamarin version 4.5.0.266-pre3 or higher)
This feature is still in development and is only available if enabled by customers. To enable this experience, go to Options > Environment > Preview Features and enable 'XAML Binding Failure Window'.
Known Limitations: Clicking on binding failures in the panel does not yet navigate to code. Also attaching to a running process will not work, you must F5 into the debug experience for this experience.
Editor
- In this release, the legacy Find in Files experience has been deprecated and all users are being moved to the new experience. The Editor team is working with folks who leave feedback in Developer Community who are experiencing issues with the modern Find in Files experience.

The new Xcode preview has a more refined user interface and some really smart features such as Apple's LLVM compiler which is capable of detecting and even correcting the the mistakes that you make when writing your your code on it's own. SDK's of mac OS X and iOS are present in Xcode 4.2 along with other tools to set you up for the development of applications for Mac and iDevices. Below is Apple's official description for the Xcode 4.2 developers preview 5.
Xcode is the complete toolset for building Mac OS X and iOS applications — and with Xcode 4, the tools have been redesigned to be faster, easier to use, and more helpful than ever before. The Xcode IDE understands your project's every detail, identifies mistakes in both syntax and logic, and will even fix your code for you. Quite simply, Xcode 4 will help you write better code.
With Apple Tv beta 4 installed on your Apple TV(second generation), you can couple it with your iPhone, iPad, or iPod Touch running on the iOS 5 Beta 5 to try out their compatibility and the feel of the new features such as iPad 2 screen mirroring, Facetime mirroring and photostream etc. Most probably these would be the last of the Beta versions before the final versions are released for general public as well. If you own a developers account you can head over to Apple's developer website and start tinkering with these new offerings.
