We're currently evaluating ASP.NET Core for a task manager with web UI for our .NET application (a data transformation tool). Our target audience is people with little or no technical background therefore we can't ask them to setup IIS. I looked at other web-servers in .NET stack (e.g. Suave), but nothing looked sufficiently lightweight and easy to use. Although, we're looking for ASP.NET Core over .NET 4.5.1, not .NET Core.
It's a good suggestion although at this point I don't see why it would be radically better for our case than ASP.NET Core. Our application has very few API endpoints and very low qps rate, so we don't need extensive routing or balancing. At the same time, since we have previous experience with ASP.NET the learning curve would be flat, while nancyfx is a new animal for us.
