EF reduce usage of memory

[endesapt]

I have an ASP.NET Web API project and I am using some background service where i update my DB and add new data(~20000 rows) every 8 hours But even for the first iteration of queries my app is using 400mb of memory(though in DB data it is only ~25mb) And memory usage keeps increasing after each iteration.

I tried to use GC.Collect() and it caused some effect, but it still consumes 660 mb after 3 calls to DB There are photos of memory profiler( red line states for end of one iteration) Memory usage without GC

Memory usage with GC

I have 2 quesitions:

1. Am i doing something wrong with DbContext so it doesnt dispose correctly?
2. If not, how can i decrease memory usage in my application

I created test ASP.NET project that shows my problem EFMemoryTest
