Unable to get method SyntaxTree.ParseFile in new nuget of Roslyn?

.net, asp.net-mvc, c#, compilation, roslyn

Solution

The API simply changed a little bit, one way to do it is :

var path = @"C:\...\SomeFile.cs";
using(var stream = File.OpenRead(path))
{
    var syntaxTree = CSharpSyntaxTree.ParseText(SourceText.From(stream), path: path);
}

Problem

I have installed nuget for `Roslyn` with `Install-Package Microsoft.CodeAnalysis -Pre` but i'm still unable to get the method `SyntaxTree.ParseFile` as I want to pass code in a `.cs` file Any clue about why is it so ? How can I pass file here?
