.Net 6 - Failed to free the memory region

[wokhan]

Hi, I'm probably way too late to the party but still it could help someone.
According to dotnet official sample, and if I'm not mistaking, coreclr signatures changed and in fact the issue you see is a side effect of the coreload library failing to properly load .NET, which, if you look thoroughly, causes the target process to restart with a new PID.
Since it has a new PID, the following call (attemtping to inject the hook, this time), will fail, and memory won't be either freeable (or allocated in some cases I encountered) since there is no target process anymore.
Hope this helps you... as it would have helped me reconsider using .NET 7 (or 6) with CoreHook...
I may try to update this lib for .NET 6+, but looks way more complex than what I'm used to.

@wokhan Not too late but there doesn't seem to be any activity here to get this updated, I ended up just building an adapter library around https://crates.io/crates/netcorehost before moving onto my own implementation.

Hi @CryoMyst, in fact I was also interested to see how bad my C++ was nowadays, so I've been working on this the last few days.
I hope I'll have something working soon, but I'm really unsure if it will be enough or not (rebuilding a new .NET 6/7 "corehost" lib is the simple part thank to the available samples, and I'm still not done with it)..

If I succeed, I might either issue a PR here or create a fork... We'll see...
It also depends on @unknownv2, as I've seen no activity here for a few years (hoping he's fine).

Hi, I totally forgot about that, I don't know if you saw but I finally ported and rewrote CoreHook for .NET 6+... Check my github if interested.
