[Blazor page] Getting an exception when using a dash in page route parameters

[vcrobe]

Describe the bug

I get an exception when using a dash in page route parameters like this:

/edit/5-3

I'm using Blazor-server.

To Reproduce

@page "/Edit"
@page "/Edit/{Year:int}-{Number:int}"

<p>@Year @Number</p>

@code
{
	[Parameter]
	public int Year {get;set;}

	[Parameter]
	public int Number {get;set;}
}

Exception

InvalidOperationException: Invalid template 'Edit/{Year:int}-{Number:int}'. The character '}' in parameter segment '{Year:int}-{Number:int}' is not allowed.

Microsoft.AspNetCore.Components.Routing.TemplateParser.ParseTemplate(string template).

@vcrobe thanks for contacting us.

Blazor routing doesn't support that type of parameter (we call them complex parameters in ASP.NET Core) as an alternative we suggest you capture the parameter and match the value against the pattern you expect.
