System.Security.SecurityException: That assembly does not allow partially trusted callers while using HttpUtility.UrlEncode in CRM

Hi,

We got the below error in one of our Sandboxed Plugins

“System.Security.SecurityException: That assembly does not allow partially trusted callers”.

We realised it was because of using System.Web.HttpUtility class


We replaced it with EscapeDataString method and this fixed the issue.

System.Uri.EscapeDataString()

Helpful thread

Hope it helps..
