BulkSupport for InMemory Database #44

Closed mathlizee closed 7 months ago

mathlizee commented 1 year ago

Hello!

For unit and integration test purposes, I am using an InMemory database with mocked data. To do so, I created a mocked DbContext using an InMemoryDatabase. I then use this mocked context as a subsitute for my SQL Server context in my EF Core application.

However, when performing bulk operations with temp tables, I get this error: System.InvalidOperationException : Unable to resolve service for type 'Thinktecture.EntityFrameworkCore.BulkOperations.ITempTableBulkInsertExecutor'. This is often because no database provider has been configured for this DbContext. A provider can be configured by overriding the 'DbContext.OnConfiguring' method or by using 'AddDbContext' on the application service provider. If 'AddDbContext' is used, then also ensure that your DbContext type accepts a DbContextOptions<TContext> object in its constructor and passes it to the base constructor for DbContext.

This is probably because my InMemoryDatabase doesn't have BulkSupport, but I could not find a way to add it. With my SQL Server context, I do this: options => options.UseSqlServer(apiConfiguration.ConnectionString, sqlOptions => { sqlOptions.AddBulkOperationSupport(); })

My questions are:

  1. Is this the cause of this error?
  2. If so, Is there a way to add BulkSupport to an InMemoryDatabase?
  3. If it is not supported, could it be added in the future?

Best regards! Mathieu Lizee

Sorry, the lib doesn't support InMemoryProvider and there are no plans to add support for it.
