question: debugging services ran out of memory

Hi

When trying to add 40000+ bitmap images in a Hashtable, visual studio uses 32 GB of RAM. Then it terminates the program and gives following error. I use latest visual studio community 2026 and latest .NET 10 on Windows 11. My computer has 16 GB of RAM.

2 questions:

• is 32 GB the maximum amount of memory a .NET program can use on the configuration above?
• can a Hashtable hold more then 32 GB of bitmap images? In other words: is a hashtable unlimited in memory it consumes?
• is there a solution for this? if yes, what can I do to store all images in the Hashtable without getting this error and without my program being terminated by visual studio?

No. It's the debugger running out of memory, not the program itself.

can a Hashtable hold more then 32 GB of bitmap images? In other words: is a hashtable unlimited in memory it consumes?

The memory isn't held by the HashTable. It only holds a few bytes per entry. It's only limited by item count (2^31 items).

is there a solution for this? if yes, what can I do to store all images in the Hashtable without getting this error and without my program being terminated by visual studio?

The program isn't actually terminated by visual studio. It's visual studio itself can't hold the program. You can run the program without debugger.
