| microsoft.public.dotnet.framework.performance |
| I was looking at some performance counters related to my application. The private bytes comes out to be around 110 MB and the #Bytes in Heap, around, 24 MB.

| microsoft.public.dotnet.framework.performance |

So, if a garbage collection occurs while some code is inside a unsafe "fixed" block, the pinned data will not be relocated and the managed heap becomes fragmented. Doesn't ... |
