Twitter: "Want to throw together a quick web application in C#? This is what that will look like in the future.

Now, with this required hardware-enforced containerization and virtualization tech, Windows 11 will isolate applications and processes much more easily. It will be much more difficult for malware in an errantly running application to access resources it isn't supposed to. It will only access the resources in that specific application task that it infects, such as a particular browser tab.   

A new free extension for Visual Studio was released that enables developers to create cross-platform HTML5 applications exclusively using C# and XAML. 

Entity Framework is Microsoft’s flagship Object/Relation Mapper, and the recommended way to access relational databases. Entity Framework Core is a complete rewrite from the “classic” Entity Framework, building on the new multiplatform .NET Core framework and adding the ability to connect to nonrelational data sources while keeping the features that made Entity Framework Code First so popular. In Entity Framework Core Succinctly, join Ricardo Peres to explore this new version of the O/RM, from getting set up to avoiding common traps. 

Porting existing code to .NET Core used to be quite hard because the available API set was very small. In .NET Core 2.0, we already made this much easier, thanks to .NET Standard 2.0. Today, we’re happy to announce that we made it even easier with the Windows Compatibility Pack, which provides access to an additional 20,000 APIs via a single NuGet package. 

What’s new?

Here’s a sampling of the great new features and improvements in ASP.NET Core for .NET 7:

• Servers and runtime
  • Rating limiting: Limit the rate of handled requests using flexible endpoint configuration and policies.
  • Output caching: Configure output caching to reduce to more efficiently handle request.
  • Request decompression: Accept requests with compressed content.
  • HTTP/3: Built-in support for HTTP/3, the latest HTTP version based on the new QUIC multiplexed transport protocol.
  • WebSockets over HTTP/2: Use WebSockets over HTTP/2 connections.
  • WebTransport (experimental): Create streams and data grams over HTTP/3 with experimental support for WebTransport.
• 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.
• Blazor
  • 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. 

• Merge Conflict: "Take Source"/"Keep Target" is missing
• Crashes when trying to debug uwp application
• Unable to select target platform azure v12 for database project
• Fixed crashes or errors that can occur when running Visual Studio after an install action that requires a reboot.
• Fixed an issue deploying Xamarin.Android apps. This peviously required a manual uninstall of the app from the device or emulator.
• This change fixes a bug where the compiler may sometimes incorrectly remove an instruction in a C++ coroutine. 

This sample shows you how to use SQL Server Language Extensions to create a .NET Core C# program that receives two columns (ID and text) from SQL Server and a regular expression as an input parameter. The class returns two columns back to SQL Server (ID and text).
