Middleware redirect in Asp.net core Blazor server-side 3.0 error?

I am currently testing out an asp.net core 3 blazor server-side app. I built a middleware extension in f#, and called it from c# within the Configure method of the Startup class. It appears to initially attempt the redirect as the correct url is called, but I get an error page stating that the page isn't redirecting properly. What am I missing here.

F#:

type CheckMaintenanceStatusMiddleWare(next : RequestDelegate) =

    let _next = next

    member this.InvokeAsync(context : HttpContext) =

        let statusCheck = true
        if statusCheck
        then 
            Task.Run(fun arg -> context.Response.Redirect("/Maintenance"))
        else 
           _next.Invoke(context)

[<Extension>]
type CheckMaintenanceStatusMiddleWareExtensions() =

    [<Extension>]
    static member inline UseCheckMaintenanceStatus(builder : IApplicationBuilder) =

        builder.UseMiddleware<CheckMaintenanceStatusMiddleWare>() 

C#

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseCheckMaintenanceStatus();

            var connectionString = Configuration.GetConnectionString("DefaultConnection");
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }



            app.UseHttpsRedirection();
            app.UseStaticFiles();

            //app.UseCookiePolicy();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapBlazorHub();
                endpoints.MapFallbackToPage("/_Host");
            });
        }

Razor Component:

@page "/Maintenance"

<h3>Maintenance</h3>

@code {

}
