Security Exception (shared hosting)

Postby robertnzana » Sun 05 Jul 2009 10:51

ASP.NET website using MySql db and a connector I purchased (MyDirect.NET).

Local machine: All works perfectly.

Deployed to GoDaddy ASP.NET web hosting. I get this error:

Having the same problem here, and consulted my provider. He states that all IO permissions within my application folder should work just fine, and that the environment is running in medium trust, and also has the socket permission set:

class="SocketPermission"
version="1"
Unrestricted="true"
/>

So now I'm wondering, what file does the driver want to open? since it's in your driver's code, I presume you might have an idea about that.

Ps, I'm running your latest demo version, since I must first be sure this is going to work before I buy a licensed version.

Diesen, sorry for the delay. We have investigated the issue. It is necessary to have permissions for access to all directories on the machine at the moment (to GAC in our case). In the next build we will correct this situation - to have access for files inside the application directory only will be enough. Now you should use the High trust level because it has the following entry in its *.config file:
Code: Select all

A high trust level can not be set/changed on the machine, since it's shared hosting, the provider will not change any security settings just for me.

Can you tell me when the next build is going to be?
