How tall is that hill? I wrote C# professionally every day for 3.5 years. The last day was as painful as the first. I can appreciate making an investment in tools that make me more productive in the long run, but at some point it has to start paying off. Programming languages have finite useful lifetimes. Common Lisp took me years to learn well, too, but it started paying big dividends after only a couple weeks.
