RoutePatternException occurs inside of ApplicationBuilderExtensions.UseSilkierQuartz method (a project with WebAssembly.Server)

[mamift]

Hello,

I'm getting an RoutePatternException when invoking the ApplicationBuilderExtensions.UseSilkierQuartz method inside a WebAssembly.Server project.

The full exception trace is:

Microsoft.AspNetCore.Routing.RouteCreationException
  HResult=0x80131500
  Message=An error occurred while creating the route with name 'SilkierQuartz' and pattern '//{controller=Scheduler}/{action=Index}'.

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
RoutePatternException: The route template separator character '/' cannot appear consecutively. It must be separated by either a parameter or a literal value.

I think the issue is here at this line inside ApplicationBuilderExtensions.cs:

endpoints.MapControllerRoute(nameof(SilkierQuartz), $"{options.VirtualPathRoot}/{{controller=Scheduler}}/{{action=Index}}");
endpoints.MapControllerRoute($"{nameof(SilkierQuartz)}Authenticate", $"{options.VirtualPathRoot}/{{controller=Authenticate}}/{{action=Login}}");

By default options.VirtualPathRoot is always '/', so the string template is pre-prending '/' twice.

Seems to only happen when using WebAssembly.Server in the same project.

I encountered the same error in an ASP.NET Core project.

SilkierQuartz Version: 5.0.356
