[Soap-141]

Description

For diagnostics and debugging purposes my team and I would like to have Process.GetCurrentProcess().PrivateMemorySize64 working on iOS.

See https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process.getcurrentprocess?view=net-6.0 and https://learn.microsoft.com/en-us/dotnet/api/system.diagnostics.process.privatememorysize64?view=net-6.0 for more details.

Reproduction Steps

Use this code snippet on Xamarin or MAUI iOS.

var currentProcess = Process.GetCurrentProcess();
var privateMemory = currentProcess.PrivateMemorySize64;

Notice it's throwing exception.

Expected behavior

Should not throw any exception and work like it's supposed to.

Actual behavior

Throws an exception.

Regression?

Known Workarounds

No response

@akoeplinger is there a native way that iOS supports working set? I thought process was largely unsupported out of the lack of fork abilities, but is introspection also not supported?

[akoeplinger]

We're using proc_pidinfo to get these details on macOS and unfortunately that API is not allowed by Apple on the iOS App Store so we had to remove it: https://github.com/dotnet/runtime/issues/61265

That said, there's nothing stopping you from using this API on your own e.g. behind a DEBUG flag that you never compile for a build that ends up on the App Store.

I'll take a quick look to see whether there is some allowed API that gives just the memory details though.
