Cc @danroth27 I'm not knowledgeable about the blazorwasm templates - are they still intended to be part of .net 8?

[baronfel]

@aguacongas can you run 'dotnet --info' and drop that information into the issue description please?

[aguacongas]

@baronfel already in the dotnet Info section, click the output link

[baronfel]

Thank you! Clearly I needed my coffee this morning.

[baronfel]

I was able to create this template on RC1 with the --hosted option and the --framework option individually, but not in concert. This makes me think this is a bug in the template engine or dotnet new command itself rather than a bug in the template. @dotnet/templating-engine-maintainers we may need to prioritize triaging this one.

@aguacongas are you able to use this template in VS's New Project Dialog to successfully create the hosted, .NET 8.0 version of the template?

@danroth27 how critical is this version of the blazorwasm template specifically? trying to judge priority of this vs. the other work that the Template Engine devs have lined up before the release.

[aguacongas]

Using VS Dialog box the hosted option is not available but we can use .NET 8.0

[danroth27]

Hi @aguacongas. In .NET 8 we've removed the --hosted option from the Blazor WebAssembly template because hosting a Blazor WebAssembly app in an ASP.NET Core host is now covered by the new Blazor Web App template, which unifies Blazor Server and Blazor WebAssembly into a single model that also support static server rendering.

With .NET 8 RC1 you can create a Blazor Web App that is set up to run components on WebAssembly like this: dotnet new blazor --use-wasm. Note this will only set up a single page to run on WebAssembly. The rest of the app uses static server rendering.

In .NET 8 RC2 you can create a Blazor Web App that uses interactive WebAssembly rendering globally for the entire app like this: dotnet new blazor --interactivity WebAssembly --interactive-all, or dotnet new blazor -int WebAssembly -ai in the short form. This will set up the entire app to run on WebAssembly just like an ASP.NET Core Hosted Blazor WebAssembly app, but also with prerendering enabled. Going forward the Blazor WebAssembly project template is only for cases where you want to host a Blazor app as a static site with no ASP.NET Core host. To better reflect that, we have renamed the Blazor WebAssembly project template in .NET 8 RC2 to Blazor WebAssembly Standalone App.

Note that if you have .NET 7 installed you will still see the .NET 7 version of the templates alongside the new .NET 8 templates.

[danroth27]

Closing as this issue as the behavior is by design.

[baronfel]

ah, of course! I confirmed that you can see the --hosted option is no longer present if you run dotnet new blazorwasm --framework net8.0 --help - in the Template Engine, since Framework is used to select the matching template, help itself can be modified based on the framework.
