Blazor - .NET Preview 8 - Breaks Fluxor - Not clear which part breaks

[christoment]

Hi Fluxor team,

Just grabbed the latest .NET Preview 8 + Blazor, but Fluxor seems to failed on initialisation.
It works previously with .NET Preview 7.

I attached the stacktrace from the browser, but I'm not sure which part breaks. Hopefully this can help the team to debug it.

Any advice to get this working?

Thanks!

Could you send me a repro?

[AlexRtmSystems]

Hi,

I have the same problem with .NET 5 Preview 8.

To reproduce: Create a new Blazor App with ASP.NET core hosted. Add <Fluxor.Blazor.Web.StoreInitializer /> as first line in App.razor and

var currentAssembly = typeof(Program).Assembly;
builder.Services.AddFluxor(options => options
.ScanAssemblies(currentAssembly)
.UseRouting());

in Program.cs Main() method. Run and following error occur:

[mrpmorris]

reproduced!

[mrpmorris]

Fixed in 3.7

@christoment Thanks for doing a demo of Fluxor on YouTube. I've added a link to your Twitter profile + to the video on the main project page under Getting Started.

[christoment]

Thanks @mrpmorris !

Hope that the video will help everyone to quickly get started in Fluxor.

Cheers,
Chris.

I'm using with Blazor Server-Side (.net 8). Not getting any exceptions, but it's not working either. I think the problem is with the new App.razor () component in .net 8.

here is my App.razor

<script src="_content/MatBlazor/dist/matBlazor.js"></script> <script src="_framework/blazor.web.js"></script> <script src="_content/Fluxor.Blazor.Web/scripts/index.js"></script>
