RAVENDB The name "Store" doesn't exist in the current context

I've been working on getting this to work all day, and haven't had any success. I want to clean up my code and separate different chunks of code into different classes and functions. Here is a chunk of code that refuses to run.
using System;
using Raven.Client.Documents;
namespace RavendbTest
{
class Program
{
static void Main(string[] args)
{
var store = new DocumentStore
{
Urls = new[] { "http://localhost:8080" },
Database = "Tasks"
};
store.Initialize();
}
static void Checking()
{
Console.WriteLine("Login or Sign Up? (L/S)");
string userInput = Console.ReadLine();
if (userInput.ToLower() == "l")
{
Console.WriteLine("Logging you in");
}
else if (userInput.ToLower() == "s")
{
Console.WriteLine("Signing you up\n");
Console.Write("First Name: ");
string firstName = Console.ReadLine();
char firstNameInitial = firstName.ToLower()[0];
Console.WriteLine(firstNameInitial);
Console.Write("Last Name: ");
string lastName = Console.ReadLine();
char lastNameInitial = lastName.ToLower()[0];
Console.WriteLine(lastNameInitial);
Console.Write("Email: ");
string email = Console.ReadLine();
string combinedInitial = firstNameInitial.ToString() + lastNameInitial.ToString();
Console.WriteLine(combinedInitial);
// Checking if email has a '#' symbol in it. Determine validity
bool isVerified = false;
for (int i = 0; email.Length > i; i++)
{
if (email[i] != '#')
{
continue;
}
else if (email[i] == '#')
{
isVerified = true;
}
}
if (isVerified == true)
{
using (var session = Store.OpenSession())
{
var task = session.Load<Entity>(combinedInitial + email);
if (task == null)
{
Console.WriteLine("Creating your account");
var newUser = new Entity
{
Id = combinedInitial + email,
FirstName = firstName,
LastName = lastName,
Email = email
};
session.Store(newUser);
session.SaveChanges();
}
else
{
Console.WriteLine("This email is already in use... Would you like to login? (Y/N)");
string changeChoice = Console.ReadLine();
if (changeChoice.ToLower()[0] == 'y')
{
}
else
{
Console.WriteLine("Exiting Program");
}
}
using (var session = store.OpenSession())
{
var task = session.Load<Entity>(combinedInitial + email);
}
}
}
else
{
Console.WriteLine("Please enter a valid email address");
Console.WriteLine("Exiting Program");
}
}
else
{
Console.WriteLine("Error");
}
}
}
}
I thinking that I'm getting errors because my function checking can't see that I've already initialize a DocumentStore. Any help is greatly appreciated

C# - connecting to SQL Server

At the beginning of my journey with C#, I am developing this simple Flashcard app. It can be used for learning vocabulary in new language.
I have created Flashcard class, also have been able to create functions allowing users to enter new words, revise them and play simple guessing game.
When creating new words, program ask user how many one, would like to create. Then uses object of Flashcard function n times, filling list with them.
After every operation like this, I'd like to insert new words, and its translation into a SQL Server database, although I've encountered first problem.

Can't remove items from List with remove()

Hi I would like to remove account names by using a foreach in method readInput that sends the accounts to method DisableADUser that would disable the accounts and remove the name from the global List invalidAccounts (whole code line 7) if the operation is successful.
I have tried using the Remove method and placing it in both the if and else condition in the DisableADUser method but it does not work. How should I go about resolving this? Thanks in advance. :)
readInput method (lines 1- 13)

You can't Remove items from the list you are iterating. It messes with the enumerator to delete things out from under it. You need to copy the items you want to keep to another list instead, and then copy it back if necessary; or create a list of items you want to remove, and remove them all at once at the end.
This has a discussion of various methods: Intelligent way of removing items from a List<T> while enumerating in C#

Find all subfolders of the Inbox folder using EWS

I have the following Inbox folder structure:
Inbox
--ABC
----ABC 2
----ABC 3
--XYZ
----XYZ 2
--123
----123 A
----123 B
----123 C
I am using Exchange Web Services and the following code to find the child folders of the Inbox folder:
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
service.AutodiscoverUrl("MyName#MyDomain.com");
Mailbox mb = new Mailbox("MyName#MyDomain.com");
FindFoldersResults findResults = service.FindFolders(
WellKnownFolderName.Inbox,
new FolderView(int.MaxValue));
foreach (Folder folder in findResults.Folders)
{
Console.WriteLine(folder.DisplayName);
}
This partly works because it returns the ABC, XYZ, and 123 folders; unfortunately, it does not return the folders inside each of those folders (ABC 2, ABC 3, XYZ 2, 123 A, 123 B, 123 C).
Also, it is possible that a folder could have more than one level of subfolders inside it.
How can I write this code so that it will return all subfolders regardless of how deeply nested they may be?

You can tell EWS to do a deep traversal when searching the folders. You can do this using the FolderView.Traversal property. Your code would then be changed to something similar to the following:
FindFoldersResults findResults = service.FindFolders(
WellKnownFolderName.Inbox,
new FolderView(int.MaxValue) { Traversal = FolderTraversal.Deep });

You can page your requests and get the entire folder hierarchy from the server in just a few calls. The key is the FolderView.Traversal property, as Jacob indicates.
For example, for an Exchange mailbox with ~1,300 folders the code below only makes 2 requests. You can set your page size to whatever you like, as long as you stay at or below the server limit.
FYI: Exchange Online (Office365) caps at a maximum of 1,000 items in a response. I haven't tested, so I can't speak for any similar limits when querying an on-premises Exchange Server.
