Hello,

I'm trying to call a WS in my plugin, a simple GET query, but i'm getting always the following error message

Unhandled Exception: 
The type of the first permission that failed was:
System.Security.Permissions.SecurityPermission
The demand was for:
<IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xx"
version="1"
Flags="Assertion"/>

I tried to add

[System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Assert, Unrestricted = true)] but it didn't help

I'm online, sandbox isolation mode.

my code is

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Method = "GET";
            response = request.GetResponse();

Any idea please?

Thank you

Hello Sskod,

You can try using System.Net.WebClient.

I hope it help.

It looks like you have issues with Sandboxing of plugins. Can you please provide full code of your plugin?

Are you trying to access the web service anonymously, or passing credentials ? I'd expect you to get this error if you're trying to pass credentials, as only anonymous calls are supported - see https://msdn.microsoft.com/en-us/library/gg334752.aspx

If you have to pass credentials, you'll probably have to get outside of the CRM sandbox via the service bus or an event hook

Have you tried following code - msdn.microsoft.com/.../gg509030.aspx

One more question - what port do you use with your external endpoint and what version are you on?

This is what I expected. It seems that Microsoft in v9.0 blocks endpoint calls for any other than 80 or 443 ports. Any chance you can redeploy your endpoint to port 80?
