Error on WebClient in Custom Workflow Activity on CRM Online

Hi Everyone,

I'm a bit stuck onthis one, working code in console application triggers following error with on demand workflow :

--------------

Error Message:

Unhandled exception:
Exception type: Microsoft.Xrm.Sdk.InvalidPluginExecutionException
Message: Inheritance security rules violated while overriding member: 'Microsoft.Reporting.WinForms.LocalReport.System.Runtime.Serialization.ISerializable.GetObjectData(System.Runtime.Serialization.SerializationInfo, System.Runtime.Serialization.StreamingContext)'. Security accessibility of the overriding method must match the security accessibility of the method being overriden.

--------------

We narrowed the issue down to this snippet :

public static Stream GetStreamFromUrl(string url)
        {
            byte[] imageData = null;

            using (var wc = new System.Net.WebClient())
            {
                imageData = wc.DownloadData(url);
            }

            return new MemoryStream(imageData);
        }

Unfortunately I don't where to go from here, most posts I red indicate that it is because of the sandbox registration of the Custom Workflow Activity (It's for an online Dynamics).

I am requesting against a static .rdlc file with no authentication (Azure public blob storage).

Thanks for your kind replies !
