If I have the following, will IDisposeable still be called on DisposeableObject, or will the object remain opened because an un-handled exception is encountered?
using ( DisposeableObject = new Object() )
{
throw new Exception("test");
}

IDisposable is an interface that contains a single method, Dispose(), for releasing unmanaged resources, like files, streams, database connections and so on.
Typically, types that use unmanaged resources implement the IDisposable or IAsyncDisposable interface to allow the unmanaged resources to be reclaimed. When you finish using an object that implements IDisposable, you call the object's Dispose or DisposeAsync implementation to explicitly perform cleanup.
Dispose() does not get called in the attached code. Further more the exception that is thrown is not handled and the program blows up. You must be looking at the wrong file. "Dispose()" gets written to your temp file.
If you access unmanaged resources (e.g. files, database connections etc.) in a class, you should implement IDisposable and overwrite the Dispose method to allow you to control when the memory is freed.
A using is like wrapping your code in a try...finally and disposing in the finally, so yes, it should be called.
