The thing to realize about the .net GC is that it is precise, 
generational, compacting, and asynchronous. It also has a 
low-latency mode which is primarily used for ASP.net, which 
limits the maximum time spent in performing a single collection. 
It also supporting pinning allocations. In comparison, D's GC is 
simple, as are most GC implementations.
