Source generators is a new C# compiler feature shipped with the latest .NET 5. The feature allows C# developers to inspect source code and generate new code at compile time. Using a compile-time code generation instead of run-time code inspection could lead to a significant performance gain. Source generators are only a recent feature with having a stable version released by the end of 2020. Thus, no comprehensive guides are describing their capabilities yet, and only a few libraries use them. The primary goal of the thesis is to describe and explain C# source generators; additionally, the thesis should analyze in which standard constructs of the business logic of enterprise applications they might find their use. It is also expected to provide a solution to at least one of the constructs, which seemed appropriate during the analysis.
