.NET Framework June 2022 Security and Quality Rollup Updates

We are releasing the June 2022 Security and Quality Rollup Updates for .NET Framework.

Security

The June Security and Quality Rollup Update does not contain any new security fixes. See May 2022 Security and Quality Rollup for the latest security updates.

Quality and Reliability

This release contains the following quality and reliability improvements.

NET Runtime
  • Addresses several issues that would cause too many garbage collections under high memory load. The part of the change that reduces the number of blocking generation 2 collections under high memory load is considered a tuning change and is only active if the GCConserveMemory setting is set to a non-zero value. The part of the change that reduces needless generation 0 collections is considered an improvement and is always active.
  • Adjusted GC Heap Hard Limit configuration, as well as processor interpretation for .NET Framework container scenarios.
WPF1
  • Addresses an issue where DWM failures can cause WPF’s render thread to fail. An app can opt-in to the behavior of ignoring all DwmFlush errors by setting a regkey in HKCUSoftwareMicrosoftAvalon.GraphicsIgnoreDwmFlushErrors or HKLMSoftwareMicrosoftAvalon.GraphicsIgnoreDwmFlushErrors whose name is the full path to the .exe that wants to opt-in, and whose DWORD value is 1.
  • Addresses an issue of WPF apps not working with “Text Cursor Indicator” enabled when using RichTextBox.
Winforms
  • Improved the hardened rendering of ComboBox controls on 64 bit architectures.
  • Improved the reliability of data-bound ComboBox controls under assistive technology.
Workflow
  • Addresses an issue when users interact with the Workflow Designer they might encounter incorrectly disabled context menu items when right clicking on a variable in the component variables list.

How To Append Data to HTML5 localStorage or sessionStorage?

The localStorage property allows you to access a local Storage object. localStorage is similar to sessionStorage. The only difference is that, while data stored in localStorage has no expiration time untill unless user deletes his cache, data stored in sessionStorage gets cleared when the originating window or tab get closed. These are new HTML5 objects and provide these methods to deal with it: The following snippet accesses the current domain's local Storage object and adds a data item to it using Storage.setItem() . localStorage.setItem('myFav', 'Taylor Swift'); or you can use the keyname directly as : localStorage.myFav = 'Taylor Swift'; To grab the value set in localStorage or sessionStorage, we can use localStorage.getItem("myFav"); or localStorage.myFav There's no append function for localStorage or sessionStorage objects. It's not hard to write one though.The simplest solution goes here: But we can kee
