Database have about 1350 tables and 35650 fields. I uploaded compiled models library(EFCoreCompiledModels.zip),can reference it and compile,will show CS0240 error EFCoreCompiledModels.zip

EF Core version: Database provider: (e.g. Microsoft.EntityFrameworkCore.SqlServer) Target framework: (e.g. .8.0.0-preview.6.23329.4) Operating system: IDE: (e.g. Visual Studio 2022 17.4)

Note for triage: EFCoreStudyContextCompliedModel is 521,614 lines long.

culushishui commented 1 year ago

Think you reply. Triage is some tables in one dbcontext and other some tables in another dbconext ?

In EF Core 7, my compiled model file was 13,880 lines long, and turned into 453,786 after updating to EF Core 8. The new CreateRelationalModel function, which is over 430,000 lines long, seems to be the culprit, since the Initialize function seems to be similar to the one in EF Core 7.

As a workaround you can remove the CreateRelationalModel method. EF will then fallback to 7.0 behavior and create it at runtime.

@AndriySvyryd We should doc this workaround in the breaking changes.
