memory garbage-collection clr windbg sos

Can I run a .NET garbage collection from WinDbg?

I'm looking into why a managed process is using a lot of memory. Is there a way to run GC.Collect(3) from WinDbg, so that I can focus on the actual memory allocation?

Solution

I don't think there is any way to run a .NET garbage collection from WinDbg, but I also don't think it is necessary.

See Rico Mariani's Performance Tidbits - Tracking down managed memory leaks (how to find a GC leak) for information about finding out what kind of stuff is on your heap.
