问题 I have put together a HTTP driven API using the WCF WebAPI that uses the PUT verb. When hosted inside of an MVC3 project that is hosted upon IIS Express, everything works as designed. However, when I unit-test I'm occasionally wanting to test the transport aspects rather than just against my own resources. My unit-tests fail with a 405 - MethodNotAllowed. Again, exactly the same service hosted in IIS works (where I enabled the PUT and DELETE verbs in the configuration file). How can I get the

问题 I'm fairly new to the WCF Web API, I have a basic service going and trying to leverage the full power of using HttpResponseMessage as return type. I am trying to return a List and getting the following error around which I can't get around. This is a very basic straight-up XML service. Any ideas would be appreciated. Thanks.

问题 I am using the Background Transfer to upload Photographs to my Web Service. As the Photograph uploads can consume significant time and memory, I thought it might be a nice idea to use the background transfer request to accomplish this. After the photo is uploaded, I want to obtain the Id of the uploaded photo and then use it for post-processing. However, it turns out I can't do that in a background transfer request. Per my understanding, Background Transfer works using the following logic
