Issue with AreaRegistration in Global.asax

Are areas supported?

This line:

```
AreaRegistration.RegisterAllAreas();
```

in

```
protected void Application_Start(object sender, EventArgs e
```

of

```
global.asax.cs
```

results in the error below (slightly munged).

The test is

```
[TestMethod]
public void CanIgetMasterPage()
{
var sut = WebApplicationProxy.GetPageByLocation("~/MasterPages/Main.Master") as Main;

Assert.IsNotNull(sut);

}
```

and the base test class is

namespace xxx.yyy.WebFormsTestSpike
{

```
public class WebFormsTestBase
{

protected readonly MockRepository _mockery;
protected readonly Mock contextMock;
protected readonly Mock responseMock;
protected readonly Mock requestMock;

public WebFormsTestBase()
{

_mockery = new MockRepository(MockBehavior.Loose);

contextMock = _mockery.Create();

responseMock = _mockery.Create();
contextMock.SetupGet(c => c.Response).Returns(responseMock.Object);
contextMock.SetupGet(c => c.IsDebuggingEnabled).Returns(true);

requestMock = _mockery.Create();
contextMock.SetupGet(c => c.Request).Returns(requestMock.Object);

InitializeWebApplicationProxy();
}

private void InitializeWebApplicationProxy()
{
Uri codeBase = new Uri(GetType().Assembly.CodeBase);
var currentFolder = new DirectoryInfo(Path.GetDirectoryName(codeBase.LocalPath));
var webFolder = currentFolder.Parent.Parent.Parent.GetDirectories("xxx.yyy.Web")[0];

WebApplicationProxy.Create(webFolder.FullName, true);
}
}
```

}

InnerException:

Start in global.asax.cs at Global.Application_Start, where AreaRegistration.RegisterAllAreas() raises the exception. Read the CanIgetMasterPage test and WebFormsTestBase.InitializeWebApplicationProxy setup, then run the test to reproduce the failure. Done means establishing whether area registration is supported by this harness and resolving or clearly documenting the observed behavior.
