求助：.NET Core 2.0 OData EnableQuery属性不支持查询操作及问题反馈

Hey there, let's walk through how to address this problem you're seeing with that beta OData package, plus how to report the bug if you want to contribute to fixing it.

First: Beta Versions Are Unstable by Design #

The key thing to note here is you're using Microsoft.AspNetCore.OData v7.0.0.0-beta1—beta builds are meant for testing, not production, and they're full of unpolished features and known (or unknown) bugs. The query operation failure you're hitting is almost certainly a bug that got fixed in later stable releases.

Quick Fixes to Get Your Queries Working #

1. Upgrade to the Latest Stable Version #

This is the best long-term solution. Beta versions shouldn't be used for live apps, and updating to a stable release will resolve this query issue (along with a bunch of other bugs). To do this, update your package reference in your .csproj file:

<PackageReference Include="Microsoft.AspNetCore.OData" Version="[Replace with latest stable version]" />

You can find the latest stable version on the official NuGet page for the package.

2. Stick with the Beta? Use Your Workaround Properly #

If you absolutely have to stay on the beta build, you can formalize the workaround you already found. Create a custom EnableQueryAttribute that skips the problematic validation:

public class CustomEnableQueryAttribute : EnableQueryAttribute
{
    public override void ValidateQuery(HttpRequest request, ODataQueryOptions queryOptions)
    {
        // Bypass the default validation that's blocking your filter/select/top/skip operations
        // You can add custom validation here if you need to enforce query rules later
    }
}

Then replace the default [EnableQuery] attribute on your controller actions with [CustomEnableQuery]—that should keep your queries working as expected.

How to Report the Bug #

If you want to flag this issue to the OData team so they can confirm it (and ensure it's fixed in future builds), here are the official channels:

• GitHub: The Microsoft.AspNetCore.OData project lives on GitHub. You can open a new issue there, include details about your reproducible sample, the beta version you're using, and the workaround you discovered.
• Microsoft Q&A: Post your issue in the ASP.NET Core or OData section—Microsoft engineers and community experts monitor this space and can help validate the bug.

A Quick Reminder #

Always avoid using beta packages for production applications. Stable releases are thoroughly tested and far more reliable. If you're testing beta builds, be sure to check the project's existing issues and release notes first—your problem might already be reported or fixed in a newer beta/stable build.
