# 92 - Creating SOLID Code: Liskov Substitution Principle

Great screencast Steve!!

Would it not be better to implement interfaces since the base classes don't have any code?

Stephen

@Stephen:

Great point!  Now that you mention it, the base classes are starting to look like 'legacy warts' on the design rather than playing a useful role here any more!

You get the pair-programmer-bonus-of-the-month-award for pointing that out.  Maybe now I need to do an L.1 installment to clean that up :D

Thanks for the comment -- it points out the the narrow application of any one design principle can sometimes blind one to the quality of the overall design (I'm sure there's a forest-for-the-trees principle waiting to be named for that pattern too!).

Thanks for the feedback and I'm glad you're finding value in the content.

I sure find value in your screencasts. Keep up the good work!

With this dimecast, we are now SOL.  Here's looking forward to I and D!

@Dale,

What do you mean SOL?

He means that the three first letters in SOLID have been covered.

Thank you for the SOLID screencasts. Very informative.

Stephen what Visual Studio pluggin are you using. I'd like to give it a try.

You're seeing me use CodeRush + Refactor!Pro from http://devexpress.com.  I prefer these tools over the more-commonly-recommended Resharper but that's frankly naught but personal preference (I find the IDE integration of the visual cues from CR+R to be better than R# IMO).

Developer Express usually has fully-functional but time-limited trials of CR+R that you can download from their site if you're interested.

-Steve B.

PS: I make ZERO $$$ off any recommendations of tools so make your own choice for yourself and pick what yoiu find best suits you :)

Thanks Steve. I have used Resharper in the past. I will try this to compare.
