Is there a way to trigger a garbage collection in a .NET process from another process or from inside WinDBG?
There are the Managed Debugging Assistants that force a collection as you move across a native/managed boundary, and AQTime seems to have button that suggests it does this, but I can't find any documentation on how to do it.

You can force garbage collection either to all the three generations or to a specific generation using the GC. Collect() method. The GC. Collect() method is overloaded -- you can call it without any parameters or even by passing the generation number you would like to the garbage collector to collect.
Garbage Collection occurs if at least one of multiple conditions is satisfied. These conditions are given as follows: If the system has low physical memory, then garbage collection is necessary. If the memory allocated to various objects in the heap memory exceeds a pre-set threshold, then garbage collection occurs.
GC.Collect() Net Framework provides a new mechanism for releasing unreferenced objects from the memory ,this process is called Garbage Collection (GC). In some rare situations, forcing a Garbage Collection may improve your application's performance. The garbage collection (GC )class provides a GC.

Basically, use PerfView:
PerfView.exe ForceGC [ProcessName | Process ID] /AcceptEULA It's not intended for production use.

Well... there's the immediate window. If you have the luxury of attaching to the process, I supposed you could manually GC.Collect in the immediate window.
Bigger question: why would you want to manually induce GC.Collect? It's a nasty habit, and indicative of much bigger design issues.
