Hi Team,

I am creating Core 6 web api project for Umbraco 9.5 version. I create one api class which is

[Route("api/StoreLocator")]
[ApiController]
public class StoreLocatorController : UmbracoApiController
{

now i added some default settings in start.up class file which is

 services
                 .AddSwaggerGen()
                 .AddUmbraco(_env, _config)
                 .AddBackOffice()
                 .AddWebsite()
                 .AddComposers().Build();

 app.UseUmbraco()
                .WithMiddleware(u =>
                {
                    u.UseBackOffice();
                    u.UseWebsite();
                    u.UseUmbracoCoreMiddleware();
                })
                .WithEndpoints(u =>
                {
                    u.UseInstallerEndpoints();
                    u.UseBackOfficeEndpoints();
                    u.UseWebsiteEndpoints();
                });
