    <p>I am having a very frustrating problem in Visual Studio. I am using Resharper, and writing tests in Nunit.</p> <p>If I set a breakpoint, it does get hit, however Step In/Over and Continue do not work, and the test never finishes. Even if I set two break points, continuing won't hit the second. If I debug a test without a breakpoint, it finishes fine. </p> <p>Also, often and intermittently, when I try to debug a test by setting a break point, I can't evaluate the contents of variables, but instead see this message:</p> <p><code>Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation.</code> </p> <p>I am using Visual Studio 2010.</p> <p>Please let me know if you have any ideas of what to look at... I have scoured the web, but without any luck.</p> <p>Happy to provide further information if needed.</p> <p><strong>EDIT - Example of method</strong></p> <p><em>Test:</em></p> <pre><code>[Test] public void OneRowAddedToSourceData() { //Factory just returns System.Data.DataTable with correct columns. var sourceData = new DataTableContainerFactory().GetTargetTableContainer(DataTypeNames.EventSharedEnd); //GetRow just returns a populated row. var row = GetRow(sourceData, 123456, 123,60, 31); sourceData.DataTable.Rows.Add(row); Assert.AreEqual(1, sourceData.DataTable.Rows.Count); } </code></pre> <p>When I set a break point on the Assert statement, and try to evaluate the data table I get this problem.</p> <p><strong>UPDATE 2!</strong> So, I have narrowed this problem down to Resharper Debugging. I changed a test class to MSTest rather than NUnit, but still got both the above problems when debugging with Resharper. However, when I ran the tests with the built in VS MSTest test runner, ALL the problems had gone!</p> <p>Now I much prefer using NUnit and Resharper, so I would be very happy if someone could point me at a setting that will allow Resharper to debug properly!</p>

    1. COI have seen exactly what you are talking about. It isn't Resharper/Nunit related. It happens when you try to evaluating those variables. I'll see it when I try to expand a `List<>` or something similar (`Dictionary<,>`). If you can avoid the evaluation that causes the message, you can continue to debug. Right now, I just know that when I get that error message, I stop debugging and restart, then try not to evaluate the variable that caused the problem. Would LOVE to know how to prevent this from happening.

    2. COThanks Joel, that is a work around for some cases, however I am often trying to evaluate exactly those variables. Very frustrating! I just hope someone here can help!

    3. COIs it possible a function you're evaluating is looping continuously? Can you provide a simple example of what type of tests you're seeing this in?
