Why is Memory Usage section disabled in performance profiler?

I would like to run Memory Usage session or Object Allocation (preferable both) but I have only available types CPU Usage and GPU Usage. VS does not show any hint while given section is disabled.

I tried out several other projects I wrote and one after another all have just those two sections.

I run 64-bit Windows 10.

If .NET Object Allocation Tool option is disabled/not applicable when trying to start profiler for a Web project, ensure that Start Action is not set to "Don't open a page. Wait for a request from an external application".

This solution worked for me:

  1. Switch Project Properties -> Web -> Start Action to "Current Page"
  2. Save the project
  3. Close Diagnostic tools window and open a new one (ALT+F2)

The option .NET Object Allocation Tool should be moved from section "Not Applicable Tools" to "Available Tools"

In may case, changing the Analysis Target to Startup Project instead of Running Process and Executable fixed the issue (Project targets .NET 4.8)

It's possible that the current tool selection prevents you from selecting what you want.

For example, here's what I see:

CPU usage and Database selected

I can't select the Memory Usage tool unless I deselect both the CPU Usage and Database tools:

Memory Usage selected

In my case, Memory Usage was disabled because of project's framework version. It was set to 3.5. When I changed it to newest (on my computer 4.7.2), Memory Usage functionality starts working. After profiling, I will change framework version back to 3.5, due to our product compatibility.

Framework version settings is in: Project / Properties / Application / Target Framework
