DI Issues when using third-party libraries.

[paburgos]

Hello,

I am using Finbuckle to convert my Blazor Server App into a multitenant. I am also implementing the Azure SignalR Service.

But as soon as I put to work both together I get this error:

Microsoft.AspNetCore.Components.Server.Circuits.RemoteRenderer: Warning: Unhandled exception rendering component: Cannot provide a value for property 'Tenant' on type 'Project1.Pages.Index'. There is no registered service of type 'Project1.Data.Multitenant.MyTenantInfo'. System.InvalidOperationException: Cannot provide a value for property 'Tenant' on type 'Project1.Pages.Index'. There is no registered service of type 'Project1Data.Multitenant.MyTenantInfo'.

I have a repo with the issue: https://github.com/paburgos/SignalRFinbuckleIssue To reproduce the error is just a matter to enable SignalR service logic in startup.cs, launchsettings.json, and appsettings.json.

Here is how the services are registered for Finbuckle.MultiTenant.

I also have an issue opened directly in Finbuckle here

I am wondering if you can help me find out where the issue might be?

Sorry for the late response. When using AzureSignalR, blazor client requests are going through Azure SignalR to the server instead of triggering the server's HTTP middleware anymore. So the way that Finbuckle registers the per-tenant service inside the middleware https://github.com/Finbuckle/Finbuckle.MultiTenant/blob/f02be2508e615a4a366b61fd06d5a9d40ec2372c/src/Finbuckle.MultiTenant.AspNetCore/Internal/MultiTenantMiddleware.cs#L26 can no longer work.

The workaround I have is to resolve the MyTenantInfo inside the page:

@page "/"
@using Finbuckle.MultiTenant
@inject IHttpContextAccessor httpContextAccessor
@inject IMultiTenantContextAccessor<MyTenantInfo> accessor
@code{
    protected override async Task OnInitializedAsync()
    {
        var context = httpContextAccessor.HttpContext;
        var accessor = context.RequestServices.GetRequiredService<IMultiTenantContextAccessor>();

            if (accessor.MultiTenantContext == null)
            {
                var resolver = context.RequestServices.GetRequiredService<ITenantResolver>();
                var multiTenantContext = await resolver.ResolveAsync(context);
                accessor.MultiTenantContext = multiTenantContext;
            }
        await base.OnInitializedAsync();
    }
}
