Software reuse is a crucial external quality attribute targeted by open-source and commercial projects. Despite that software reuse has experienced an increased adoption throughout the years, little is known about what aspects of code reuse developers discuss. In this paper, we present an empirical study of 1,409 posts to better understand the challenges developers face when reusing code. Our findings show that 'visual studio' is the top occurring bigrams for question posts, and there are frequent design patterns utilized by developers for the purpose of reuse. We envision our findings enabling researchers to develop guidelines to be utilized to foster software reuse.
