However, the stack has much less room than the heap, so structs should be kept small (Microsoft recommends structs take up no more than 16 bytes)...

Performance-critical applications in managed .NET applications can be severely impacted by the GC. When the GC runs, all other threads are suspended until it completes. For this reason, it is recommended to carefully evaluate the GC processes and determine how to minimize when it runs.

One of MEF's big advantages over other technologies that support the inversion-of-control pattern is that it supports resolving dependencies that are not known at design-time, without needing much (if any) configuration. All examples require a reference to the System.ComponentModel.Composition as...
