In my experience, the first 40 minutes of a project's lifecycle is largely noise. It is much more important is to create a body of code that can be effectively grown by large teams of developers. At the risk of sounding obvious, consider creating a library in situations where you need to use C# if you find yourself doing the same thing over and over again. Of course, if you can be specific about your misgivings that may help the C# (and Clojure) ecosystems or at least help us understand what you mean.
