You slide into your office chair, cup of coffee in hand, and check your email. Another high severity ticket – your servers have crashed, and you have by tomorrow morning to figure out why. Heaving a heavy sigh, you soon find yourself sifting through tens of thousands of lines of code and logs. Morning soon passes to afternoon, fading into dusk. Finally, you find it, push the fix, and reboot the application. Minutes pass. Crash . Your night of the living dead has begun – no matter how many times you try to put this bug down, it just keeps coming back to life. We’ve all suffered from “zombie bugs” before. There are many static analysis tools on the marketplace today to help you detect bugs, many of which work by searching for a series of syntactic patterns in code. Unfortunately, due to the huge variation and complexity of coding constructs and conventions in different projects, this approach often leads to the high false positive and false negative rates for which static analysis tools...

Today, we are releasing the October 2022 Cumulative Update Preview for .NET Framework. Quality and Reliability This release contains the following quality and reliability improvements. WPF 1 Addresses an issue where a FailFast crash could occur when using WebBrowser.NavigateToString. Addresses an ArgumentOutOfRangeException that can arise when calling ListBox.ScrollIntoView while there are pending changes to the visual tree that will change or clear the underlying ItemsCollection. Addresses an ArgumentException “Width and Height must be non-negative” that can arise in an ItemsControl with grouping enabled, custom margins on the GroupItems, collapse/expand of GroupItems enabled, and run in high-DPI. Addresses an issue where the opt-out switch Switch.System.Windows.Controls.ToolTip.OptOutOfWCAG21ToolTipBehavior didn’t quite restore the 4.8 behavior, in particular the way it honors Switch.UseLegacyToolTipDisplay (which controls whether keyboard tooltip behavior is enabled). .NET...

In .NET 7, our focus for System.Text.Json has been to substantially improve extensibility of the library, adding new performance-oriented features and addressing high impact reliability and consistency issues. More specifically, .NET 7 sees the release of contract customization , which gives you more control over how types are serialized or deserialized, polymorphic serialization for user-defined type hierarchies , required member support , and much more. Getting the latest bits You can try out the new features by using the latest build of System.Text.Json NuGet package or the latest SDK for .NET 7 , which is currently RC. Contract Customization System.Text.Json determines how a given .NET type is meant to be serialized and deserialized by constructing a JSON contract for that type. The contract is derived from the type’s shape — such as its available constructors, properties and fields, and whether it implements IEnumerable or IDictionary — either at runtime using reflection or...

We are pleased to announce official .NET MAUI support in Microsoft.Identity.Client 4.47.0 to easily add authentication into your apps. In this blog we will take a look at how to perform authentication in .NET MAUI apps to acquire the desired token. Commonly authentication is done in three ways: Basic – This is used when authentication is done for both personal and corporate accounts without using a broker (or Authenticator). For clarity, personal account mean Microsoft personal account such as Outlook, Hotmail etc. With Broker – This is intended for corporate accounts where an extra layer of security is added by using Authenticator/Broker. This is useful for MFA and is required to comply with other security policies such as conditional access. B2C – This is used when the end user is allowed to login using OAuth2 credentials such as Google, Facebook etc. This does not support broker. We provided one sample for each type Samples . All the samples use the standard Acquire Token S...
