Try out Blazor updates for .NET 6, where we try out four new features.
Using Visual Studio 2022 preview, you can see how the following features work for Blazor in .NET 6:
.NET 5 had the ability to load a Blazor WebAssembly application to the server before being presented to the client. One of the benefits of prerendering is to make it easier for search engines to crawl an application.
However, it didn't have any ability to store data. This was a particular problem if there was an API call when the application was initialised. It would have to make the same API call twice.
.NET 6 has fixed this through the use of the
There is now the ability to read a Razor component parameter through a querystring parameter. This is thanks to the
In addition, it also allows us to specify the querystring parameter name to map the property to.

This is the software that will need to be installed onto your machine.
These are the steps to get the application working.
You are now ready to go.
RoundTheCode.BlazorDotNet6.sln in Visual Studio 2022.
Start the project in Visual Studio. As we are prerendering the Blazor WebAssembly application, it should be the
RoundTheCode.BlazorDotNet6.Host project that is set as the startup project.
https://localhost:4500, to test out the Blazor .NET 6 updates.
Watch our video where we go ahead and implement these four new Blazor features for .NET 6.
