What it is
A .NET Conf 2021 talk by Steve Sanderson on what .NET 6 adds to Blazor WebAssembly. It covers native dependencies (such as SQLite or a Rust library compiled to WASM), AOT compilation for near-native speed, smaller bundles, and hot reload, demonstrated with the BlazeOrbital sample app.

EDIT 2022-08-18: I haven't tested this myself, but this should now be possible by leveraging web components. Can we consume a Blazor component as a Web Component within a regular non-Blazor HTML page? [LINK] [this video] (I recommend the whole video by the way, excellent content!) Having an existing ASP.NET MVC5 app which is not feasible to rewrite all in one go, how can we start incorporating (client-side) Blazor to replace parts of that app? EDIT: We would need to have pages where parts of it are MVC5 and other parts are Blazor where this would work seamless for the end user. From what I have found so far the best (and only?) option would be to host Blazor in a different site and include it as

This should be achieved much more easily with .NET 6 as Blazor now supports native dependencies. You can compile the OpenCV C++ or OpenCV.js to wasm using emscripten and add a native file to your csproj as shown below. <NativeFileReference Include="path-to-output-file" /> You can then go ahead and P/Invoke into the native code. In this [this video] , Steve Sanderson demos a very similar scenario. You can also check out the docs [LINK] on Native Dependencies in Blazor for more information.

In .NET 5 you can't use SQLite with Blazor in web app/browser. However, as of .NET 6, you can include native dependencies in Blazor WebAssembly. Inside dotnet conf 2021 they even show show that. It's working very nicely. You can see this in action here: Steven Sanderson on Blazor WebAssemby @ .NETConf21 [this video] (approx. 30 minutes watch time). A code sample for the above is available on Steve Sanderson's GitHub repo [LINK] .

Cites metsman · 2022-01 · Stack Overflow · on “What is the Benefit of using SQLite with Blazor WASM?”
I was watching this video from Steve Sanderson which demonstrates using SQLite with Blazor Web Assembly [this video] and I am contemplating using it in one of my projects. I am just trying to understand what the benefit is. It seems, from whatever information I was able to find, that the actual SQLite database resides in memory. In his project he is synchronizing it with IndexedDB for persistence. If that is the case, how is that better than storing your data as an object list in memory, and using Linq to query the objects directly, instead of Entity Framework to query from the SQLite database? You can also persist your objects to IndexedDB if that is required. I was never under the impression th

Starting .Net 6 , it is now possible to use SQLite with Blazor Web Assembly . Here are the steps, Add reference to following Nuget packages: Microsoft.EntityFrameworkCore.Sqlite SQLitePCLRaw.bundle_e_sqlite3 - Currently in preview as of posting this answer. This package is to avoid NativeFileReference of e_sqlite3.o . Add the following in .csproj to avoid unwanted warning from popping out. <AllowUnsafeBlocks>true</AllowUnsafeBlocks> <EmccExtraLDFlags>-s WARN_ON_UNDEFINED_SYMBOLS=0</EmccExtraLDFlags> Add the following code in Program.cs . This is required to avoid runtime exception - Could not find method 'AddYears' on type 'System.DateOnly' public partial class Program { /// <summary> /// FI

@PanagiotisKanavos "You can't use EF on a browser." this is incorrect. Using EF on the client side (browser) is one of the new features of .NET 6 as bricelam has indicated. [this video] and [LINK] are good references.
