I got a curiosity while using CLR.
How can it be done that accessing object data by CLR application is safe
even while garbage collector is working? Is the GC thread running in
realtime priority for this for example?
Please reply. Thanks in advance.

The CLR pauses all threads while garbage collecting. Thats why it is a
performance hit to call it yourself and to keep invoking it with short term
memory allocations.

Hello Hyun-jik Bae,

Just to add Ciaran's post:
GC pause nothing, it just ask CLR to suspend/resume threads.
It's not just simple suspension, there are some cases how threads are suspended
based on whether threads are in managed code or not

It isn't.... the gc moves everything. That's why the GC suspends all
threads in managed code before it starts running.

Hello Ben,

A small addition - GC calls functions to do the suspension and the resumption
as a service provided in the CLR.
It's the work of CLR and EE(Execution Engine) to manage this
