ASP.NET > LinqKit > doesn't implement IAsyncEnumerable.

Posted at

ASP.NET CoreにてLinqKitを使った際に、ToListAsyncを呼び出したら以下のようなエラーになりました。　の解決の備忘録

The source IQueryable doesn't implement IAsyncEnumerable. Only sources that implement IAsyncEnumerable can be used for Entity Framework asynchronous operations.

環境：

  • ASP.NET Core2.1
  • DB:SQL Server

LinqKit.Microsoft.EntityFrameworkCore

当初はLINQKit.Coreを使っていましたが、それは間違いで、LinqKit.Microsoft.EntityFrameworkCoreを使う必要があった模様です。

こっち正解

NuGet Gallery | LinqKit.Microsoft.EntityFrameworkCore 1.1.15

こっち違う
