The numbers looked right. The types didn’t.
An Entity Framework error sent me back to the database schema. The C# property was decimal. The SQL column was real.

Things I’m figuring out.
Senior full Stack Software Developer with production code deployed to Fortune 500 Companies, medium sized businesses, colleges, universities, and other governmental organizations.
I’m Kevin. I mostly write C# and work on .NET applications, but I like getting into web development, 3D, and game development too. This is a place to share what I’m working on, what’s giving me trouble, and what finally worked.
01 Field notes
3D / Debugging
The fix was in the branch that never ran.
A roof connection looked wrong on one side. Before changing more geometry, I had to check which code was actually running.
C# / LINQ
One question, two levels of collections.
Does any roof segment on any residential building have gable steel? Getting the LINQ operators in the right order made the query straightforward.
SQL / Data changes
What happens if I run this SQL script twice?
Adding missing dealer-category associations was only half the job. I also wanted a second run to leave the data alone.

Things I’ve been building
Some of this is work. Some of it is just something I wanted to try.
A
eQuote-Connect
I work on a .NET building design and quoting application, along with its web portal and 3D models. There’s quite a bit going on between entering a building’s dimensions and getting a finished quote.

Developer field notes
I wanted somewhere to keep project updates and write down things I’ve figured out. If something here helps somebody else avoid the same headache, even better.

- CSS

03 About
I like software that solves a real problem.
I’m a senior software developer, mostly working with C#, WPF, and .NET. Before my current role, I taught web and game development at Iowa Lakes Community College. I still really enjoy figuring something out and helping someone else understand it.
Outside of work, I’m making a game with my daughter and usually listening to rock or metal. TOOL is a favorite.

I’m on YouTube too.
I’ve got quite a few videos over there. Take a look around.
