 At the core of the library is IFileSystem and FileSystem. Instead of calling methods like File.ReadAllText directly, use IFileSystem.File.ReadAllText. We have exactly the same API, except that ours is injectable and testable.
 
-    public class MyComponent
-    {
-        readonly IFileSystem fileSystem;
+```csharp
+public class MyComponent
+{
+    readonly IFileSystem fileSystem;
 
-        public MyComponent(IFileSystem fileSystem)
-        {
-            this.fileSystem = fileSystem;
-        }
+    public MyComponent(IFileSystem fileSystem)
+    {
+        this.fileSystem = fileSystem;
+    }
 
-        public void Validate()
+    public void Validate()
+    {
+        foreach (var textFile in fileSystem.Directory.GetFiles(@"c:\", "*.txt", SearchOption.TopDirectoryOnly))
         {
-            foreach (var textFile in fileSystem.Directory.GetFiles(@"c:\", "*.txt", SearchOption.TopDirectoryOnly))
-            {
-                var text = fileSystem.File.ReadAllText(textFile);
-                if (text != "Testing is awesome.")
-                    throw new NotSupportedException("We can't go on together. It's not me, it's you.");
-            }
+            var text = fileSystem.File.ReadAllText(textFile);
+            if (text != "Testing is awesome.")
+                throw new NotSupportedException("We can't go on together. It's not me, it's you.");
         }
     }
+}
+```
 
 The library also ships with a series of test helpers to save you from having to mock out every call:
 
-    [Test]
-    public void MyComponent_Validate_ShouldThrowNotSupportedExceptionIfTestingIsNotAwesome()
+```csharp
+[Test]
+public void MyComponent_Validate_ShouldThrowNotSupportedExceptionIfTestingIsNotAwesome()
+{
+    // Arrange
+    var fileSystem = new MockFileSystem(new Dictionary<string, MockFileData>
     {
-        // Arrange
-        var fileSystem = new MockFileSystem(new Dictionary<string, MockFileData>
-        {
-            { @"c:\myfile.txt", new MockFileData("Testing is meh.") },
-            { @"c:\demo\jQuery.js", new MockFileData("some js") },
-            { @"c:\demo\image.gif", new MockFileData(new byte[] { 0x12, 0x34, 0x56, 0xd2 }) }
-        });
-        var component = new MyComponent(fileSystem);
-
-        try
-        {
-            // Act
-            component.Validate();
-        }
-        catch (NotSupportedException ex)
-        {
-            // Assert
-            Assert.AreEqual("We can't go on together. It's not me, it's you.", ex.Message);
-            return;
-        }
+        { @"c:\myfile.txt", new MockFileData("Testing is meh.") },
+        { @"c:\demo\jQuery.js", new MockFileData("some js") },
+        { @"c:\demo\image.gif", new MockFileData(new byte[] { 0x12, 0x34, 0x56, 0xd2 }) }
+    });
+    var component = new MyComponent(fileSystem);
 
-        Assert.Fail("The expected exception was not thrown.");
+    try
+    {
+        // Act
+        component.Validate();
+    }
+    catch (NotSupportedException ex)
+    {
+        // Assert
+        Assert.AreEqual("We can't go on together. It's not me, it's you.", ex.Message);
+        return;
     }
 
+    Assert.Fail("The expected exception was not thrown.");
+}
+```
 We even support casting from the .NET Framework's untestable types to our testable wrappers:
 
-    FileInfo SomeBadApiMethodThatReturnsFileInfo()
-    {
-        return new FileInfo("a");
-    }
+```csharp
+FileInfo SomeBadApiMethodThatReturnsFileInfo()
+{
+    return new FileInfo("a");
+}
 
-    void MyFancyMethod()
-    {
-        var testableFileInfo = (FileInfoBase)SomeBadApiMethodThatReturnsFileInfo();
-        ...
-    }
