System.Net.Http, Version=4.0.0.0 The system cannot find the file specified.

We are running AppDynamics.Agent.Coordinator 4.2.8. When this service is running, we get this error.

Could not load file or assembly 'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

The file is present in the GAC and the Fusion logs show:

The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.

Is this the same issue as referenced in : https://community.appdynamics.com/t5/NET-Agent-Installation/Could-not-load-file-or-assembly-Newtonsoft-Json/td-p/24192

I looked at the release notes for 4.3.1, but did not see a resolved issue specifically for GAC access issues.

Thank you!

Hi,

Can you try adding <add-assembly-reference enabled="false" /> section at your config.xml located at C:\ProgramData\AppDynamics\DotNetAgent\Config

Your config.xml will look like following ( content in bold needs to be added). Once you add this section please recycle Agent Coordinator Service and instrumented section

<app-agents>

<profiler>

<add-assembly-reference enabled="false" />

</profiler>

....

</app-agents>

Let us know if this does not resolve the issue.

Thanks,

Raunak

Raunak,

We were able to resolve the issue by upgrading the agent to 4.3.

Thanks for getting back to us.
