如何在EF 6.0中调用原始SQL查询

Question

I have a simple gridview which I need to bind with a list of users.

In EF.5.0 I could simple write

context.Users.Select(emp => new { Name = emp.FirstName, EmailId = emp.EmailId, UserId = emp.UserId }).ToList();

However, I don't see the .ToList() method anymore in EF6.0

So, I have to write an async query using ToAsyncList() . However, not sure why the below code does not work and system goes in endless execution.

protected void Page_Load(object sender, EventArgs e)
{
    var task = LoadData();
    task.Wait();
    GridView1.DataSource = task.Result;
    GridView1.DataBind();
}

private async Task<List<User>> LoadData()
{
    List<User> users = null;

    using (var context = new BlogEntities())
    {
        users = await context.Database.SqlQuery<User>("Select * from User", new object[] { }).ToListAsync();
    }

    return users;
}

Can anyone please let me know, what I am doing wrong here?

使用此代码：

var users = context.Users.SqlQuery("SELECT * FROM dbo.User").ToList();
