[MulticoreJIT] Single file deployment does not support ProfileOptimization #108270

Open FixBo opened 1 month ago

FixBo commented 1 month ago

Create app with profile enable

ProfileOptimization.SetProfileRoot(AppDomain.CurrentDomain.BaseDirectory); ProfileOptimization.StartProfile("profile");

Publish as selfcontained single file

dotnet publish --sc -p:PublishSingleFile=true

Run application

The "profile" is created with a size of only 64 bytes

According to my research, it's because of this check https://github.com/dotnet/runtime/blob/19da949dbc1e462e8404799b9218754cf571c8d0/src/coreclr/vm/multicorejitplayer.cpp#L452
