Azure.Search.Documents throws error while adding CORS to the Index (Programmatically)

I'm using azure cognitive search to index my data. I've upgraded to the latest Azure.Search.Documents (version 11) package. Previously I was using Microsoft.Azure.Search
When I added CORS programmatically (Line No 5) I get the below error.
Console.WriteLine("Creating Index...");
FieldBuilder fieldBuilder = new FieldBuilder();
var searchFields = fieldBuilder.Build(typeof(Hotel));
var searchIndex = new SearchIndex("hotels", searchFields);
searchIndex.CorsOptions = new CorsOptions(new List<string> { "*" });
Error:

So from my trial and error methods, I found that you will have to set the MaxAgeInSeconds
Slight modification to the code which worked for me :
var cors_option = new CorsOptions(new List<string> { "*" });
cors_option.MaxAgeInSeconds = 300;
searchIndex.CorsOptions = cors_option;
When I had commented to the MaxAgeInSeconds, was provided with the same error you were :

Error when calling method on web api controller - .Net Core 1.1 / EF 1.1

A few hours ago I posted a question, but in my haste to post the question before going to a meeting, I posted the wrong thing. I have deleted it, and here is the correct version:
I am developing a .Net Core 1.1 Web API using EF Core 1.1, which connects to a MySQL database using Pomelo.
It connects properly, but when I try to read a certain record:
http://localhost:50082/api/houses/3
I get the following error:
An unhandled exception occurred while processing the request.
ArgumentOutOfRangeException: Index was out of range. Must be
non-negative and less than the size of the collection. Parameter name:
index System.ThrowHelper.ThrowArgumentOutOfRange_IndexException()
Here is what my controller looks like:
private readonly InspectionsContext _context;
// GET: api/Houses/5
[HttpGet("{id}")]
public async Task<IActionResult> GetHouse([FromRoute] int? id)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
var house = await _context.Houses.SingleOrDefaultAsync(m => m.HouseId == id);
if (house == null)
{
return NotFound();
}
return Ok(house);
}
The error happens on this line:
var house= await _context.Houses.SingleOrDefaultAsync(m => m.HouseId == id);
House is just a standard class matching the corresponding table in the database. And there IS a house - and only one house - in the database with ID = 3.
Any ideas why I'm getting this error?
UPDATE:
Here is the full StackTrace of the error:

You have to instantiate your context object. Try making your SingleOrDefault call like:
using (var _context = new InspectionsContext())
{
var house = await _context.Houses.SingleOrDefaultAsync(m => m.HouseId == id);
}

Ok, it looks like it was some column that - most probably Pomelo - didn't like. I deleted all columns and kept only 3 basic columns (and int, a bool and a varchar) and it works. I'll have to try figure out which column it was... As soon as I figure it out, I'll post... Thanks everyone for your help

IIS Directory Services

I am trying to get the website id from IIS on Windows Server 2012 R2. I want to fetch the Id, then add a website pointer for the website in IIS. I'm not sure where to grant the permissions for the code to work and at the same time, not leaving my web server vulnerable.
Here is my code for fetching Id
string result = "-1";
DirectoryEntry w3svc = new DirectoryEntry(string.Format("IIS://{0}/w3svc", "localhost"));
foreach (DirectoryEntry site in w3svc.Children)
{
if (site.Properties["ServerComment"] != null)
{
if (site.Properties["ServerComment"].Value != null)
{
if (string.Compare(site.Properties["ServerComment"].Value.ToString(),
"website.com", true) == 0)
{
result = site.Name;
break;
}
}
}
}
return result;
This is the error that is thrown:
Access is denied.

It was a simple thing to sort out.
So I just changed the Identity of the ApplicationPool to LocalSystem and it worked 100%.

Merging WCF webservice to my web application returns an exception

I would like to add an reference for WCF weather forecast webservice in my application.The thing is I have done everything correctly,but i am lacking somewhere else.It throws an Exception.The Exception message is in the bottom of this post.Somebody out there please help me to fix this.Unles or until fixing this i couln't move to the next phase.
My Source Code is here:
public partial class Testing : System.Web.UI.Page
{
weather.WeatherForecastServiceClient ws = new weather.WeatherForecastServiceClient();
protected void Page_Load(object sender, EventArgs e)
{
SortedDictionary<string, string> objDic = new SortedDictionary<string, string>();
foreach (CultureInfo ObjectCultureInfo in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
{
RegionInfo objRegionInfo = new RegionInfo(ObjectCultureInfo.Name);
if (!objDic.ContainsKey(objRegionInfo.EnglishName))
{
objDic.Add(objRegionInfo.EnglishName, ObjectCultureInfo.Name);
}
}
foreach (KeyValuePair<string, string> val in objDic)
{
Country.Items.Add(new ListItem(val.Key, val.Value));
}
}
protected void callwebservice_Click(object sender, EventArgs e)
{
Result.Text = "Result" + ws.GetForecastByCity(City.SelectedItem.ToString(), Country.SelectedItem.ToString());
}
protected void Country_SelectedIndexChanged(object sender, EventArgs e)
{
string[] cities = ws.GetCitiesByCountry(Country.SelectedItem.ToString());
City.DataSource = cities;
City.DataBind();
}
}
This is my Exception

You have implemented the service correctly. You can confirm this by running GetCitiesByCountry (it will return a list of cities). It is just that the method GetForecastByCity does not currently work.
Try any of these APIs instead.

Problems in aspnet membership provider

I am using asp.net memebership
I log out the applcation by writting this code for log out
if (Membership.GetUser(HttpContext.Current.User.Identity).IsOnline) ;
{
FormsAuthentication.SignOut();
Response.Redirect(FormsAuthentication.LoginUrl);
}
Response.Redirect("loginpage.aspx");
After then I started the application and gettig the error in code block of authetication .below I am writtng a code and error message
else if (User.Identity.IsAuthenticated == true && Membership.GetUser( Membership.FindUsersByName(User.Identity.Name)).IsOnline==true)
{
FormsAuthentication.SignOut();
FormsAuthentication.RedirectToLoginPage();
MembershipUser currUser = null;
string gt = null;
if (HttpContext.Current.User != null)
{
currUser = Membership.GetUser(true);
gt = currUser.Email;
}
/// string temp = User.Identity.GetProfile().ID;
//string query = "Insert into user_tbl(MemberID)(" + temp + ")";
//Response.Redirect("UserPanel.aspx");
//return;
}
here Membership.FindUsersByName(User.Identity.Name)).IsOnline==true) I am getting this error

Or you could also use Request.IsAuthenticated which dosent get the whole user object and just checks authentication.

According to Visual Studio, Membership.FindUsersByName returns MembershipUserCollection. You pass that object to the Membership.GetUser method, which does accept a parameter of the object type, but that object is supposed to be a user's ID (a GUID in ASP.NET). So, the exception is quite expected: you're trying to pass a collection of users, while the method expects a single user ID.
If you need to check whether a user is currently logged in, you can simply do this:
if (Membership.GetUser() != null)
See this MSDN Library article for more information on the method.
