在ASP.NET Core 3.0 Blazor客户端应用程序中使用OData

Question

1. 创建的ASP.NET Core 3.0 Blazor客户端应用程序
2. 创建了.NET Standard 2.0类库，并使用OData V4客户端代码生成器扩展生成了OData代理类
3. 已添加类库作为Blazor应用程序的项目参考
4. 我尝试使用OData客户端从服务器消耗一些数据，但出现以下错误：

async void IncrementCount()
{
    MyContext context = new MyContext(new Uri(@"http://localhost:8080/Svc"));
    context.IgnoreResourceNotFoundException = true;
    var res = await context.Companies.ExecuteAsync();
    var count = res.ToList().Count();
    currentCount = count;
}

这是限制吗？

注意：相同的代码在.NET Framework Console应用程序中正常工作

使用ODada连接服务使CSB（客户端Blazor）的生活更加轻松。但是，如前所述，生成的代理可与服务器端blazor一起使用，对于CSB，它会给出错误。微软的家伙需要为此努力，以实现出色的开发。
