Dear Typemock team,

The following code can be executed and passes in VS2010 but fails in VS2012:

namespace ConsoleApplication1
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using TypeMock.ArrangeActAssert;
using Microsoft.VisualStudio.TestTools.UnitTesting;

public class TestProgram
public void TestTypemock()
Uri fakeUri = new Uri("http://www.ecarinsurance.co.uk");
ISessionDetails fakeSessionDetails = new SessionDetails(fakeUri);
Isolate.WhenCalled(() => fakeSessionDetails.AbsoluteUrl).WillReturn(fakeUri);

/// <summary>
/// Represents session details returned by provider
/// </summary>
public interface ISessionDetails
/// <summary>
/// Gets Url concatenated with Session id for card capture
/// </summary>
Uri AbsoluteUrl { get; }

public class SessionDetails : ISessionDetails
/// <summary>
/// Initialises a new instance of the <see cref="SessionDetails"/> class.
/// </summary>
/// <param name="absoluteUrl">The absolute Uri of the session.</param>
public SessionDetails(Uri absoluteUrl)
this.AbsoluteUrl = absoluteUrl;

/// <summary>
/// Gets the URI of the Access Control Server - the issuing bank's server that does the 3DS check with the cardholder.
/// </summary>
public Uri AbsoluteUrl { get; private set; }


The output is:

This is the final issue I face in upgrading our development environment.

Thankyou for your support so far,

Thanks for the report. I'm trying to reproduce it.

Are you using .NET 4/4.5 in both VS 2010 and VS 2012?

It can be reproduced by copying the code, pasting into a unit test project and referencing Typemock

It doesn't make a difference which .NET Framework is used (easily changed by a single dropdown in the project properties window, under 'Application' tab on the left-hand side and changing the 'Target framework'):

VS2010 does not target .NET 4.5.

VS2010 - .NET 3.5 PASS
VS2010 - .NET 4.0 PASS

VS2012 - .NET 3.5 FAIL
VS2012 - .NET 4.0 FAIL
VS2012 - .NET 4.5 FAIL

I cannot do anything more to help you than this.

We've fixed the bug. The fix will be part of the next release, 7.1.4.

Meanwhile the attached file can be used, please place it in the install directory of Isolator instead of the file that exists there.

Please let me know if it works.

Hi there,

I can confirm that this makes the unit test code I posted originally now pass. We are still experiencing the same symptoms for a few of our tests but I suspect this is being caused by another issue I'm yet to investigate.

Thankyou for your prompt fix,

I have the same issue with Typemock 7.4 and VS 2012 Update 3 on Windows Server 2008 R2 Standart.
Are you sure, that your fix is still work?
