Application break if the name contains a dot! (Blazor)

[GianlucaLocri]

• Version: ElectronNET.Core 0.3.0 Latest
• Target: .net 8

Steps to Reproduce:

1. Create a new Blazor Web App project. Important! include a dot in the name like "BlazorApp.UI"
2. Follow instructions on main repo page for blazor project (so program.cs will contain the line app.MapRazorComponents<BlazorApp.UI.Components.App>();)
3. Enjoy a mysterious unhandled error

My app contains a dot, and it still works though? Maybe it's a net8.0-specific issue.

My projects also contain a name - works.

Please provide a reproducible, otherwise we cannot investigate this. What I suspect is that you are actually facing another issue - as you wrote... mysterious ;).

I tried with .net9 and same result :(
I've attached 4 super minimal samples (two in .net8 and two in .net9). As you can see, project with a dot in name result in rendering error...
I cannot really understand the source of that behaviour...

This appears in the electron window DevTools. Have you any idea of what to look for? I am really squeezing my head for days.

Apparently .net10 works. But it is very strange... So is .Net <10 not supported by this?

[FlorianRappl]

No that has nothing to do with it. As mentioned my example also worked and it's .NET 8.

Also I won't open the zip. Please provide reproducibles in form of a repo hosted here. Thanks!

@FlorianRappl here it is the repo. I included only the problematic .net8 sample.

When i look in the web dev console the isolated css file is not found and or generated on windows. Works fine on mac.

[AeonSake]

replace the dot with a dash for the isolated CSS path: <link rel="stylesheet" href="@Assets["Blazor8-UI.styles.css"]" />

[GianlucaLocri]

@markatosi OMG you are a lifesaver mate...
I've done this:
<link rel="stylesheet" href="Blazor8-UI.styles.css" />
since @assets seems to be a .net9+ thing, and now it is working as expected!

Just to be precise, I even discovered that the simple installation of ElectronNET.Core break the project without touching anything else!
So, starting from the plain blazor sample and doing dotnet add package ElectronNET.Core will raise the issue for me.
That was really driving me crazy. I don't fully understand why this is the case, but at least I have a fix now.

[FlorianRappl]

Can we be precise about "break the project"? Because what I initially thought is that nothing starts or works, but now it seems to be a discussion about the CSS / asset path, which actually is anyway an anti-pattern with the provided name. I'd rename the asset to app.css and live happily in any case (dot, dash, whatever - should not be that verbose for no reason)...

I don't think we do anything in that area - so I don't see it in our responsibility to change here something (but I will check to verify).
