Plugins and products are compiled in a restricted mode that prevents a substantial number of .NET features from being used.
These restrictions are in place to prevent potentially malicious code from being deployed on the uMod platform.
It is NOT possible to disable the sandbox without recompiling uMod from source. Shared hosts will often prevent server owners from overwriting uMod binaries for this reason.
The list of namespaces restricted by the sandbox includes, but is not limited to:
There are some exceptions to the above list, and they are:
Extensions are generally not sandboxed, meaning that any code deployed as an extension will have unmitigated access to all .NET libraries.
For this reason, we do not generally accept extensions except in the most needful cases. If code is submitted as an extension, the author ought to be prepared to demonstrate why it absolutely must be deployed as an extension.
