File class doesn't recognize Exists or CreateText methods

A question relating to ASP.NET (4.5.1) MVC 4. I want to create a file and write a line into that file. To my understanding this is very easy i just do the following:

public static void Main() 
{
    string path = @"c:\temp\MyTest.txt";

    if (!File.Exists(path)) 
    {
        // Create a file to write to. 
        using (StreamWriter sw = File.CreateText(path)) 
        {
           sw.WriteLine("Hello");
           sw.WriteLine("And");
           sw.WriteLine("Welcome");
        }   
    }

    // Open the file to read from. 
    using (StreamReader sr = File.OpenText(path)) 
    {
        string s = "";

        while ((s = sr.ReadLine()) != null) 
        {
            Console.WriteLine(s);
        }
    }
}

But when i call the File class it won't work. It does not know the methods Exists, CreateText. I don't understand it i did import System.IO. So what is the problem?

UPDATE

Found the solution in my project i imported System.IO and System.Web.MVC. The solution is to call the File class with the full path like so:

if (!System.IO.File.Exists(path)) 
    {
        // Create a file to write to. 
        using (StreamWriter sw = System.IO.File.CreateText(path)) 
        {
           sw.WriteLine("Hello");
           sw.WriteLine("And");
           sw.WriteLine("Welcome");
        }   
    }

Problem : I suspect that you have different class in your Project with the name of File. so it is referring to that File instead of System.IO.File.

Solution : i'd suggest you to use fully qualified namespace to access the File class from System.IO to avoid the ambiguity as below:

if(!System.IO.File.Exists("path"))
{


}
