推荐答案

RC后，这个问题是固定的，你也将除了500内部服务器错误得到错误的详细信息。 （这个问题是固定的虚拟主机方案只能虽然）。

Post RC, this issue was fixed and you will be getting error details also apart from the 500 Internal Server Error. (This issue is fixed for Web Host scenarios only though).

您可以执行以下操作以获得实际的异常可能格式化的WriteToStream方法过程中发生的细节。

You could do the following to get the details of the actual exception which might be occurring during a formatter's WriteToStream method.

ObjectContent<IEnumerable<Product>> responseContent = new ObjectContent<IEnumerable<Product>>(db.Products.Include(p => p.ProductSubcategory).AsEnumerable(), new XmlMediaTypeFormatter()); // change the formatters accordingly

            MemoryStream ms = new MemoryStream();

            // This line would cause the formatter's WriteToStream method to be invoked.
            // Any exceptions during WriteToStream would be thrown as part of this call
            responseContent.CopyToAsync(ms).Wait();
