Support for earlier versions of .NET?

I want to use Hangfire on a lot of our client sites, but unfortunately, alot of them are still using .net 3.5, a few even 2.0. I won’t be able to use Hangfire unless there is some versions available for at least 3.5 and SQL 2005. Is this an option?

At least, if it’s not an option, is it possible to run my 3.5 tasks on another hangfire service? Is there any documentation on this?

@jstrez77 unfortunately there is no possibility to run Hangfire on .NET versions less than 4.5 and there are no plans to support earlier versions - a lot of work needs to be done here.
