Remarks

Transparent assemblies can be accessed from Silverlight application code and cannot expose access to any protected resources or functionality.

Note:
Transparency is enforced by the just-in-time (JIT) compiler, not by the security infrastructure code. Applying this attribute to an assembly allows the assembly to access only transparent and security-safe-critical types and members regardless of its permission set, including full trust. Transparent code that accesses a security-critical type or member results in a MethodAccessException being thrown.
