I do have a question related to this topic because I want to start a project with the Blazor WebAssembly App template but it is no longer only those two that you mention. according to a video it should look like this: User's image

I would like to know if the way I have it is the same or similar: Imagen cargada

and the result of the video after finishing it looks like this with the file explorer but I get it without the .Shared section at the end : User's image

No, you pick client as the interactive render mode to create an asp.net hosted WASM blazor app.

ok so when choosing the interactive rendering mode as a client it could be similar to the mode I am looking for in the last image of the file explorer ?

Which in any case would be to choose the Web Assambly option in the interactive rendering mode.

Yes, you want web assembly render option.

because you are using asp.net hosted, the server project will load the client project dll to do a static pre-render. The client project will build a WASM dist that is copied to the server project.

Hi @Carlos Enrique Canales L�pez , the screenshot you shared already gave you the answer. It has to choose .Net version before .Net 8.

In .Net 8, blazor imports a new template named blazor web app and removed blazor server, and the ASP.NET Core Hosted option has been removed from the Blazor WebAssembly template too. You can see the description in this section.

So that if you choose .Net 7 or .Net 6, you will be able to see this option. But both of the versions are out of support now.

Blazor web assembly asp.net core hosted template helps the Blazor web assembly app to set up a seamless integration between client and server with shared logic and models, and since the client project is added to the server project so that if we want to deploy the app, we just need to publish the server project. In my opinion, interactive auto render mode in blazor web app might be a good replacement, as interactive auto render mode project has server project and client project too.

@Carlos Enrique Canales L�pez Hi, do you have any other concerns on this question?

Hi Carlos,

What you’re experiencing relates to recent changes in the Blazor project templates introduced with .NET 8. This typically occurs when developers are searching for the classic "Blazor WebAssembly App" with the "ASP.NET Core Hosted" option, but only see the new "Blazor Web App" and "Standalone WebAssembly" templates.

Here’s how you can troubleshoot and resolve it:

In .NET 8, Microsoft has unified the Blazor templates. The "ASP.NET Core Hosted" option is no longer available in the same way. Instead, you should use the "Blazor Web App" template and select the "WebAssembly" render mode for client-side functionality. This approach gives you a similar structure, allowing for both server and client logic, and supports shared code.
If you specifically need the old "ASP.NET Core Hosted" template, you can still use .NET 7 or .NET 6, where this option is present. However, keep in mind that these versions are out of support, so it’s recommended to adapt to the new template structure if possible.

You can also find a detailed walkthrough in our documentation here:

ASP.NET Core Blazor project structure (Microsoft Docs)

I hope this helps you get things back on track quickly! If you agree with my suggestion, feel free to interact with the system accordingly!
