    <p>Primarily developing in C#, my work has been in the healthcare industry for the past 9 years, creating custom solutions for large clinical and reference laboratories, in order to interface admissions, order and results messages via HL7 v2.x protocols. </p> <p>I have extensive experience refactoring legacy VB6 applications, in order to eliminate bugs and inconsistent behavior, leverage improvements in performance and clarity in the recent versions of the .NET framework, and create code that is more testable and maintainable.</p> <p>I also have experience in VB.NET, Entity Framework, and Microsoft SQL Server. I'm familiar with many design paradigms and principles, including SOLID principles, dependency injection/IOC, and test-driven development.</p> <p>I use Git for source control, and the GitFlow workflow for managing releases, bug fixes and new feature branches.</p>

    1. COUsing Derived Value it seems possible to get [False Negative](http://xunitpatterns.com/false%20negative.html) results if your tests are written in C# and your SUT is written in VB.NET. In my code, R# suggested using `StringComparison.Orginal` with `LastIndexOf` in the C# test, but not in the VB.NET-written SUT. The R# suggestion isn't the problem, but it indicates that using Derived Value either tightly couples you to a particular .NET language, or expose you to [sneaky differences that exist between languages](http://stackoverflow.com/a/14931907/533958)

    2. COThanks, Mark, also for the embedded references. In using Structural Inspection, should the readonly properties be part of the interface or only the implementations under test (assuming there exists an `IBuilderStrategy` which `BuilderStrategy` implements)? Also, I would think that it would be better to expose these properties *as the need arises* in unit testing, rather than expose all dependencies as a routine matter (although, I suppose that in practicing TDD, this would all happen naturally). Do you have an opinion on any of that?

    3. COThanks for deciphering this one! Mixed emotions when the answer turns out to be a bug in the library I'm using… I stumbled onto this by accident because some of my XXXBuilder classes were sealed, some not. Discovered the argument about whether to seal classes in absence of a good reason to not seal, or do the opposite. Seems like sealing classes can cause unit testing friction - care to share an opinion on the matter?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
