Entity framework uses a lot of memory

Question

Here is a image from the ANTS memory profiler. It seens that there are a lot of objects hold in memory. How can I find what I am doing wrong?

Answer 1

I have a hunch you don't dispose the context.
I suggest disposing the context whenever you done interacting with database.

Use using statement whenever you create the context.

[Edit]

As far as I can see, you cache and don't dispose your EFUnitOfWork object. It is disposable, which is correct, but I don't see when disposable is called. Seems like you hold a reference to the context for all application run time.
Moreover, you create and hold one context per thread, which will make it even worse.

I can't tell you for sure where you should put Dispose or using, as I don't know the usages.
You could put it probably to your Commit method, but I don't know if the Commit called only once during database interaction session.

Also, your design might be overcomplicated.

If I were you, I would:

• Find the way to dispose the context using current code, as a short-term solution
• Simplify the design, as the long-term solution

If I had time I would do long-term solution right away.
But again, I can't tell if the complexity of your design is justified, as I don't know how big your application is and what it does and what the requirements are.
