### Scope

|
Edge
|
||
|
|
|
||
|
|
### Version Introduced
|

|
|
### Source Analyzer Status

|
|
Not planned

|
|

|
|
### Change Description
|
||
|
|
Messages in WCF web services hosted in Internet Information Services (IIS) or ASP.NET Development Server that exceed maxRequestLength (in ASP.NET) or maxReceivedMessageSize (in WCF) have different error code
|
||
|
|
|
||
|
|
The HTTP status code has changed from 400 (Bad Request) to 413 (Request Entity Too Large), and messages that exceed either the maxRequestLength or the maxReceivedMessageSize setting throw a ProtocolException exception. This includes cases in which the transfer mode is Streamed.

|
### Recommended Action
|
||
|
|
This change facilitates debugging in cases where the message length exceeds the limits allowed by ASP.NET or WCF.
|
||
|
|
|
||
|
|
You must modify any code that performs processing based on an HTTP 400 status code.
