ODataMediaTypeFormatter is case sensitive causing error during formatting


I receive the error below when accessing my People Feed at: http://localhost:51155/api/people If I capitalize 'People' ie: http://localhost:51155/api/People, it works just fine.

<m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
<m:message xml:lang="en-US">An error has occurred.</m:message>
The 'ObjectContent`1' type failed to serialize the response body for content type 'application/atom+xml; charset=utf-8'.
The related entity set could not be found. The related entity set is required to serialize the payload.

Can you take a look to see if this can be fixed at our layer or this is limited by ODataLib?

OData protocol itself is case sensitive. Entity set names are case sensitive. So, this is expected to fail. That said, we used to throw a very bad error (HTTP status 500) as the bug description shows. We have a better error now - a 404 Not Found.

There is a different bug tracking making the OData uri's case insensitive. You can find it here - https://aspnetwebstack.codeplex.com/workitem/366.

I am closing this and we will use that bug to track as it has more votes.
