Integration Manager eConnect error: Could not load type System.Runtime.Diagnostics.ITraceSourceStringProvider

By Steve Endow

This is a quick note about an obscure error that I received when trying to use Integration Manager 2013 to run an eConnect integration.


eConnect error - Could not load type System.Runtime.Diagnostics.ITraceSourceStringProvider


The error isn't particularly meaningful, so there's no way to troubleshoot it directly.  Fortunately the error is unique enough that a Google will provide several results, such as this thread:

The recommended solution is to install / reinstall .NET 4.5.2.  But I verified that I already had 4.5.2 on my server, so that seemed odd.

Then I re-read the original question--note that the user having the issue reports that they just upgraded their server from Windows 2008 to 2012?

Coincidentally, I also upgraded my server from 2008 R2 to 2012 R2 last week.  It would seem that the Windows upgrade process breaks something about the .NET 4.5 installation.

So I downloaded the .NET 4.5.2 web installer and reinstalled it.


After .NET 4.5.2 was reinstalled, the error went away.  Small victories!
