Microsoft.EntityFrameworkCore and System.Linq namespace conflict #29

Closed anthonyreilly closed 3 years ago

anthonyreilly commented 3 years ago

Apps using this, Microsoft.EntityFrameworkCore and System.Linq at the same time may see these errors, or similar:

error CS1061: 'DbSet' does not contain a definition for 'Where' and no accessible extension method 'Where' accepting a first argument of type 'DbSet' could be found (are you missing a using directive or an assembly reference?)

Due to a namespace conflict in Microsoft.EntityFrameworkCore and System.Linq, as the new System.Interactive.Async places some extension methods in System.Linq.

https://github.com/dotnet/efcore/issues/18124

This issue is due mostly to System.Interactive.Async - solving it may require removing async support in 3.0 or using an alternate method for processing async result batches.

Looking at removing the use of System.Interactive.Async entirely, and using the native async streams: https://docs.microsoft.com/en-us/dotnet/csharp/tutorials/generate-consume-asynchronous-stream Appears to be possible to include this for netstandard2.0 clients via the Microsoft.Bcl.AsyncInterfaces package https://www.nuget.org/packages/Microsoft.Bcl.AsyncInterfaces/

removed System.Interactive.Async entirely, and switched to using the native async streams. included in v3 Beta 2 https://www.nuget.org/packages/NetCoreForce.Client/3.0.0-Beta2

Linq package still has a reference to System.Interactive.Async, but that can be removed later as it doesn't impact the primary packages.
