Company standards: C#.NET vs VB.NET vs. whatever.NET

Question

Just a question that came up from time to time at my old job when we were considering fleshing out our development staff with additional bodies. Does it really matter, if you are a .NET development house, if your developers all code in one language vs another.

I probably started out like alot of the 4million other folks there with Visual Basic way back when, and then migrated to VB.NET. Another developer we had at the time came from a C background and migrated over to C#.NET. Basically he was able to code very quickly in his native language and I was able to do so in mine and since our projects did not really overlap there was no issue until our boss basically said we need to switch to C#... for no other reason than standardization.

So I guess the 'subjective' part of the question is, is it better to sacrifice productivity for consistency? Now I should quantify this in saying we were a SMALL shop, less than 5 developers and given how most of our project plans were done on cocktail napkins its not like we were going for 6-Sigma anytime soon so it was not like 'standards' were a hard and fast rule.

Thanks.

Answer 1

C# is definitely becoming the preferred avenue for Microsoft and it would make sense to choose a language that all developers to use simply based on the fact that if developers move between tasks, having the projects in a uniform language (not to mention coding conventions) will make the maintenance on those projects much easier for everyone involved.

Answer 2

If it helps, I recently wrote an article on my blog looking back at my decision to standardize our development shop on VB.NET over C# and how well my various assumptions have held up and things hindsight has shown me.

Here's a link: "A Manager’s Retrospective on the C# versus VB.NET decision"

As to whether you should standardize the whole shop on one language. I'd say there are definite benefits. The most obvious one is that switching back and forth when you work on different projects is going to incur some mental overhead to re-acclimate yourself each time. Granted, it is going to be less if you have to do it frequently, but to justify the extra complexity there would have to be some offsetting benefit.

Ultimately my advice is to standardize on one or the other based on the following criteria:
(1) If you have a large VB code-base there is a good argument for standardizing on VB.NET.
(2) If everything else is equal, I'd lean towards C# for a number of reasons mentioned in the above article.
(3) Carefully take into account your current team's preferences and the general consensus among developers in your market that you would try to recruit. Language choice is a big deal for morale and hiring.
