Gheorghe Marius asked this question:
Question: Are there any plans to add support for memory mapped files in Whidbey ? If no...why ?
The answer is no Gheorghe. The why comes down to priorities, there simply wasn't enough interest in the feature at the point we were deciding what makes it into Whidbey, and what doesn't. We have become aware recently of the demand for this item, and we will be exploring it for the near future after Whidbey.
