How to call async query in EF 6.0

I am trying to bind a gridview using EF 6.0 raw Sql query with Async, but the system goes on for endless execution and task.Result is never populated.

What I have tried:

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

private async Task<list<user>> LoadDataAsync()
    {
        List<user> users = null;
        using (var context = new BlogEntities())
        {
            users = await context.Users.SqlQuery("Select * from [User]").ToListAsync();
        }

        return users;

    }

Can anyone please let me know, how to call the async method and get the data bind successfully.
