NAV Team: Client Add-in can fail with communication error (HTTP 413) in the Microsoft Dynamics NAV 2015 Web Client

[Blog bot]

Based on a very interesting development request about a drag-and-drop Client Add-In targeted for both Windows and Web clients for Dynamics NAV, we have been able to identify a communication error with Microsoft Dynamics NAV 2015 when users select and upload multiple files using a client add-in in the Dynamics NAV Web client.

You might have heard about this through MVP blogs such as http://vjeko.com/blog/drag-and-drop-...cs-nav-2013-r2.

The issue is related to the fact that callback service requests has been limited to the WCF default message size (48 Kb). This turns out to be a problem for all partners who develop custom Client Add-Ins that send a discrete amount of data.


How to resolve this issue with Microsoft Dynamics NAV 2015:

1. Update MaxReceivedMessageSize on WCF binding to a suitable value as described in an earlier blog post.
   This value is taken from system.web/httpRuntime maxRequestLength (the default value should be 4 Mb).
2. Download and deploy – at the very least the platform files – CU 10 for Microsoft Dynamics NAV 2015 (Build No. 42222) or a later CU in order to let the platform files update the WCF message size as indicated in bullet point #1.

Please note that this feature was enhanced in Microsoft Dynamics NAV 2015 while earlier versions still stick with the WCF default message size and limitation.
