scenarios CS1061: 'IQueryable<T>' does not contain a definition for 'ToListAsync' - ASP.NET Core 3.1 and Entity Framework
I'm converting an old project and I'm upgrading from an older version and I'm experimenting with I've been struggling with this for a few days now and could really use some help... I'm working with a frustrating scenario while trying to implement asynchronous data retrieval in my ASP.NET Core 3.1 application using Entity Framework Core. I've set up my DbContext and repositories following best practices, but when I attempt to call `ToListAsync()` on an `IQueryable` collection, I'm getting the behavior: `CS1061: 'IQueryable<T>' does not contain a definition for 'ToListAsync'`. To give you a clearer idea of my setup, here’s the relevant code snippet from my repository: ```csharp public class MyRepository { private readonly MyDbContext _context; public MyRepository(MyDbContext context) { _context = context; } public async Task<List<MyEntity>> GetEntitiesAsync() { return await _context.MyEntities.AsQueryable().ToListAsync(); } } ``` I've ensured that I have the necessary using directive: ```csharp using Microsoft.EntityFrameworkCore; ``` I also verified that the NuGet package for Entity Framework Core is installed, specifically version 3.1.0. The question continues even after cleaning and rebuilding the solution. I tried switching my `IQueryable` to `IEnumerable` to see if that would resolve the scenario, but it only led to the method no longer being asynchronous and resulting in performance drawbacks. I'm not sure if there's a missing package or configuration setting that I might have overlooked. Could anyone provide insight into why `ToListAsync` might not be recognized in this context? Any help would be appreciated! My development environment is Linux. What am I doing wrong? Is this even possible? Am I missing something obvious? The project is a web app built with Csharp.
