We’re excited to announce that starting April 2022, we will be making monthly updates for modern .NET (.NET Core) available for server operating systems via Microsoft Update (MU) on an opt-in basis. 

Microsoft on Tuesday released fixes for 58 newly discovered security flaws spanning as many as 11 products and services as part of its final Patch Tuesday of 2020, effectively bringing their CVE total to 1,250 for the year. 

We are thrilled to announce that the webhint browser extension has moved from beta to its v1 release and is now available for Insider builds of Microsoft Edge, as well as for Chrome and Firefox! 

As of the 1st of July 2019 Microsoft officially ended support for Katana 3. This means that the platform we originally built-against is now unsupported and we completely stop supporting IdentityServer3 (including security bugs) for free now as well. 

.NET Core is a set of runtime, library and complier components. Microsoft uses these components in various configurations for device and cloud workloads. You can do the same for your app or service
