I’m working on some memory issues and I think I noticed a big difference between Micro .NET and “big” .NET (which I’m used to). I’d appreciate corrections if I’m wrong about this.
“Big” .NET is pretty aggressive about trying to clean things up, memory-wise. Micro .NET is pretty lazy about it. For example, if you have the following code…
string Foo = "a Really Long String, possibly made by concatenating stuff"
byte FooBytes = Encoding.UTF8.GetBytes(Foo);
byte HashedFoo = Hash(FooBytes);
byte SignedHashedFoo = Sign(HashedFoo);
Under the “big” .NET framework, after the 2nd line Foo is cleaned up and unavailable. It recognizes that Foo isn’t accessed any more and cleans it up. Under the Micro .NET Framework, Foo is available until the end of the method and will not be garbage collected, even if that means throwing an out of memory exception.
Does that jive with what other people have experienced? Or am I seeing behavior that isn’t really there?
