Hello,

1 .I can't really speak to the first point as I havent had to hire any DNN developers, but I would disagree that you need experts - an expert is usually better but it depends on the type of work you require, many extensions can leverage the powerful capabilities built into the framework to develop quickly. DotNetNuke has been around for ~10 years and has a wide ecosystem of developers who produce free extensions (see forge.dotnetnuke.com for some examples) and paid ones (store.dotnetnuke.com has around 10,0000).

2. I would definately disagree with this. One of the core strengths of DotNetNuke is that we preserve backwards compatibility between versions i.e. code written in one version with work in another. Many users have upgraded through versions without issue (you will often see people upgrading from 3.x and 4.x versions without issue i.e. sites that are 3-7 years old). The most common issue we see on upgrades are incorrect permissions (an upgrade will often update/delete files or configuration) - if you are running with a capable host this is not an issue.

Developing for DNN is just ASP .Net development. Anyone who can develop an .Net user control can create a DNN module. Anyone who can't develop a .Net user control you don't want developing anything in your web site.

My bet is that your technology partner does not understand DNN. They want to put you off DNN in favor of something they do understand.

Given the appalling general standard of developers I meet on a day by day basis (that's .Net, and non .net) I am completely convinced that choosing developers on price is folly.

To bend a well known quote - "If you think expertise is expensive, you should try ignorance."
