But I got 400 bad request when uploading more than around 100KB. I searched in internet and found some resolution about modifying max*Length or max**size. But I'm still struggling. So, I'd like to ask experts how to resolve the problem. Service code is here.

When I run this in fiddler, I also get Bad Request. When I invoke the service through the wcf test client, it works fine though. What could cause this? Service contract: [ServiceContract] public interface ITestService { [OperationContract] string GetColors(); } Implementation of ITestService: [ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)] public class TestService : ITestService { public List GetColors() { List colors= new List(); colors.Add(new Color { Name = "Red", Code = "123" }); colors.Add(new Color { Name = "Blue", Code = "323" }); colors.Add(new Color { Name = "Green", Code = "3394" }); return colors; } } Here is my web.config: platform and distributed applications IIS returns 400 “bad request” for WCF service file ★★★★★★★★★★★★★★★ APGC DSI TeamSeptember 14, 20111 0 0 0 This is an IIS hosted WCF service uses basicHttpBinding in NLB environment.

However, for this scenario, we see the 400 in IIS log instead of HTTP error log. This indicates the 400 status code should be set by the application instead of HTTP.SYS. Then, we enabled WCF trace, and we got this error.
