<p>If something goes wrong in a WCF REST call, such as the requested resource is not found, how can I play with the HTTP response code (setting it to something like HTTP 404, for example) in my OperationContract method?</p>

There is a
```
WebOperationContext
```
that you can access and it has a
```
OutgoingResponse
```
property of type
```
OutgoingWebResponseContext
```
which has a
```
StatusCode
```
property that can be set.
```
```
WebOperationContext ctx = WebOperationContext.Current;
ctx.OutgoingResponse.StatusCode = System.Net.HttpStatusCode.OK;
```
```
