Dynamic Operations Can Only Be Performed In Homogenous AppDomain.

I have faced this issue while trying to do the dynamic operation with the Timer Job in Sharepoint 2013.

After doing some research i got to know that in Sharepoint 2013 by default .Net Legacy CAS support being enabled for all the web applications and Sharepoint Timer Services.

The solution is disable the .Net Legace CAS support for the sharepoint timer service.

Here are the steps

·         Go to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\Bin

·         Locate the OWSTIMER.EXE.CONFIG and Open this file.

·         By default NetFx40_LegacySecurityPolicy is set to true. You have set enabled to false (Marked in Red).

<configuration>

   <runtime>

      <NetFx40_LegacySecurityPolicy enabled="false"/>

   </runtime>

</configuration>

Save the File. And Reset the IIS.

This will do the magic and allow the dynamic operation with the sharepoint 2013 Timer Job.

Please note any sharepoint update can replace your changes.
