- I'm also confused if the view is used or not:
- - I installed the NuGet package
- - the XML is generated
- I captured a ETW trace with WPR.exe before and after activating the view.
- In the callstacks, I see the same calls until EntityFramework.dll!System.Data.Entity.Core.Mapping.StorageMappingItemCollection+ViewDictionary::SerializedGetGeneratedViews.
- With the version which uses the views I see those lines:
- Line #, DPC/ISR, Process, Stack Tag, Stack , Count, TimeStamp, % Weight
- 45, , , , | | | | | | | | | | | | | | | | | | | | | | | | |- EntityFramework.dll!System.Data.Entity.Core.Mapping.StorageMappingItemCollection+ViewDictionary::SerializedCollectViewsFromCache, 358, , 0,08

- After the last call I got this code:

- and here for both cases the View is generated from the model/mappings:
- EntityFramework.dll!System.Data.Entity.Core.Mapping.ViewGeneration.ViewgenGatekeeper::GenerateViewsFromMapping
- So, I'm also confused if the cached views are used or not.
