Hello,

I am getting this error:
Cannot perform CAS Asserts in Security Transparent methods

Recently my hosting company has changed the trust level from FULL to MEDIUM.

I have already tried set direct=false in connection string, but no sucess.
What should we do?

The stack trace:

What should we do?

According our documentation:

In client mode - just medium trust permissions. However, if there are no dotConnect for MySQL assemblies in GAC, the UnmanagedCode flag should be added to SecurityPermission section.

If you cannot change the trust level and its settings, you may install dotConnect for MySQL with the Minimal install type on the server. This will register dotConnect runtime assemblies in the GAC. In this case your web application should work with medium trust level.
For more information, please refer to http://www.devart.com/dotconnect/mysql/ ... yment.html
