Hi
I have developed a plug-in which consumes WCF service on CRM 2011 on premises environment , and registered that as Sandbox mode
but I am getting the following error message while executing the plug-in.
“Request for the permission of type 'System.Net.WebPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed”
So I registered again but the Isolation mode as “None” (instead of Sandbox) then its working
I know in sandbox mode the plugin doesn’t have much access on system files, Is there any way we can fix this error on Sandbox mode ? ,
Regards
