Migrations don't appear to dispose resources correctly

[nirinchev]

I have a migration test that fails during cleanup on Windows because NTFS doesn't allow deleting a file that is still in use. It could very well be something that I'm doing wrong, but as far as I can tell, when a migration callback is invoked something starts using the Realm file and never releases it. For reference, here's the .NET-specific code that deals with migrations and I don't see obvious issues with it.

Ideally a C++ repro that uses the Object Store APIs is what we'll need to debug this, but at the very least I'll need to see the code of your test, as well as any error information (exception message, stack trace, debugger screenshot, etc.).

I'll prepare a simple test case that reproduces this.

@fealebenpae I've created a simple repro in this PR: realm/realm-dotnet#2334. I'm guessing you can run the .NET tests, but let me know if you want to look at it together.

[~yavor.georgiev] since there is a repro test case this should be ready for work. Assigning to you, as you are the only .NET guy around.

@fealebenpae @nirinchev is this still relevant?

[~nikola.irinchev@mongodb.com] [~yavor.georgiev@mongodb.com] Still relevant? Will you handle or should someone in the Core team?

Let's close this - there's nothing to be done on the Core side.
