New Post: QueryCacheManager as injectable service

hi Diego,


At this moment I am reviewing a solution that use Entity Framework for command and queries. The development team had identified several issues before I started my review, and show me the next issues:

• Some queries in EF are continually evaluated and did not use the QueryCacheManager ( WinDbg show the problem )
• The Compile time of this queries is potentially high, very large IQueryables with a lot of nodes, unions, joins etc..
  

After debug the code with a simple test I check that EF use correctly the Query Cache Manager... after some checks I create a custom version of EF with a parametrizable values for number of items, load factor and eviction timer in QueryCacheManager...In this solution, with a lot of tables and many different queries this custom version of EF improve the overall performance because this expensive ( in compilation time ) queries are not evaluated many times...

Really my idea is not change the QueryCacheManager, this work well, the idea is parametrize these values only.
