• Minimal APIs
  • Endpoint filters: Use endpoint filters to run cross-cutting code before or after a route handler.
  • Typed results: Return strongly typed results from minimal APIs.
  • Route groups: Organize groups of endpoints with a common prefix
• gRPC
  • JSON transcoding: Expand the reach of your gRPC services by also exposing them as JSON-based APIs
  • OpenAPI with JSON transcoding (experimenal): Use experimental support for generating OpenAPI specs for your gRPC JSON transcoded services.
  • gRPC health checks: Report and check the health of gRPC server apps.
  • gRPC client AddCallCredentials : Create clients that send authorized requests using bearer tokens.
• SignalR
  • Client results: Return client results to the server in response to requests from the server.
• MVC
  • Nullable view and page models: Nullable page and view models are now supported to improve the experience when using null state checking.

  • Custom elements: Build standard HTML custom elements with Blazor to integrate Blazor components with any JavaScript-based app.
  • Handle location changing events: Intercept location changing events to create custom user experiences when navigating.
  • Bind after/get/set modifiers: Run async logic after data binding and independently control how data binding gets and sets the data.
  • Dynamic authentication requests: Create dynamic authentication requests at runtime with custom parameters to handle advanced authentication scenarios in Blazor WebAssembly apps.
  • Improved JavaScript interop on WebAssembly: Optimize JavaScript interop call when running on WebAssembly using the new [JSImport]/[JSExport] support.
  • WebAssembly SIMD & exception handling: Improve performance with .NET WebAssembly ahead-of-time (AOT) compilation using WebAssembly SIMD and exception handling support. 

What is a popdown? It's a simple dialog that pops down from the top of your browser window once it's loaded HTML in the background. A simple way to load web forms, content, user feedback messages, media and any other in place style content. It's lightweight (4kb) and fast.  Demo

Manage events entities is pretty easy. You define few informations like a subject, a content, and maybe the most important, dates (a start and a end date of course).
You’re ready to create calendar or timeline features. Baooom! Now you need to be able to create recurrent event ! And everything is going to break.
I’ve work on this kind of feature, and here are my small advices 

• WMI Provider MSI still failing to install in 16.6
• View History on context menu in Solution Explorer doesn't do anything
• Cannot generate shim for X509Certificate2 with Visual Studio 2019 16.6.0
• Add Controller and Add New Scaffolded Item dialogs are not showing all data contexts after upgrading Visual Studio Enterprise 16.5.6->16.6.0
• Cannot open new json file
• About Microsoft Visual Studio frozen.
• Visual Studio 2019 16.6.0 Microsoft Fakes Issue
• VSSDK IVsHierarchy Regression in VS 16.6.x
• Windows 10 SDK (10.0.19041.1)- ARM64 memcpy crashes when accessing unaligned uncached memory
• Add script to SQL Server Database project does not open User Scripts list
• Fakes generation with ref argument
• Frequent soft hang with Code Analysis callstack in Open Folder project
• Visual Studio Class Designer dark theme support
• Added support for Text Template Transformation Toolkit (T4) in .NET Core projects
• Separate IntelliCode team completions model acquisition from model production.
• Addressed an issue where users may have experienced critical update or installation failures due to the WMIProvider package that would block use of the IDE. Failures in this component no longer block use of the IDE.
• Fixed a problem causing the product to stop responding when working with Xamarin projects on certain scenarios.
• Fixed a bug where VS would crash when attempting to decrypt an invalid UWP code-signing certificate

An unhandled exception of type 'System.ServiceModel.ProtocolException' occurred in mscorlib.dll

Additional information: The content type text/html of the response message does not match the content type of the binding (text/xml; charset=utf-8). If using a custom encoder, be sure that the IsContentTypeSupported method is implemented properly. The first 13 bytes of the response were: '<HTML></HTML>'. 

WebGL is an in-browser 3D renderer based on OpenGL, which lets you display your 3D content directly into an HTML5 page. Throughout this series I will cover all the essentials you need to get started using this framework. We'll start with an introduction, then we'll be building on to the framework that we used in part one as well as adding a model importer and a custom class for 3D objects. You will also be introduced to animation and controls. Lastly, we’ll take a look at lighting and adding 2D objects to your scene. 

In May 2023 over 90,000 developers responded to our annual survey about how they learn and level up, which tools they're using, and which ones they want.
