-You can run a C# project (`.csproj` file) if it's a runnable program. If the project contains a C# file with a `Main` method, and its output is an executable or `.exe` file, it will probably run if it builds successfully. If your project output is an executable file, and doesn't have a `Main` method, program executions starts with top-level statements. See [Programs without Main methods](/dotnet/csharp/fundamentals/program-structure/top-level-statements). If it doesn't run, then it might be a class library. Class libraries are not runnable on its own, but it can be referenced by other projects.
