Using DynamicRouteValueTransformer in ASP.NET Core?

Question

ASP.NET

I want to use dynamic routes: example.com/yutsuken

I did this

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");
    endpoints.MapDynamicControllerRoute<SeoTransformer>("{**path}");
});

There are a few issues that need to be fixed:
1. My SeoTransformer is called when existing routes are called, eg /Home/Index
2. My SeoTransformer is called every time /wwwroot is called, eg when a client requests .js / .css files.

In the transformer, with each call, the desired route is searched, which has a bad effect on performance
