In ASP.Net core 6.0, I want to enable CORS for localhost as well as for the list of specific domains

I have implemented something like this

public class Startup
{
    private readonly string nondevCORSPolicyName = "NonDevCorsPolicy";
    private readonly string devCORSPolicyName = "DevCorsPolicy";

    public void ConfigureServices(IServiceCollection services)
    {       
        ....
        services.AddCors(opt =>
        {
            opt.AddPolicy(name: this.nondevCORSPolicyName, builder =>
            {
                builder.WithOrigins("https://*.companydomain.com")
                    .SetIsOriginAllowedToAllowWildcardSubdomains();
            });
        });

        services.AddCors(opt =>
        {
            opt.AddPolicy(name: this.devCORSPolicyName, builder =>
            {
                builder.SetIsOriginAllowed(origin => new Uri(origin).Host == "localhost");
            });
        });
        ....
    }

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

Does it work?

I was able to achieve this as highlighted below

// CORS Policies
builder.Services.AddCors(options =>
{
    options.AddDefaultPolicy(builder =>
    {
        builder.SetIsOriginAllowed(origin => new Uri(origin).Host == "localhost" || new Uri(origin).Host == "myweb.local");
    });
});


// Enable Cors
app.UseCors();
