.Net Core
What is .Net Core?• Open source development platform maintained by Microsoft and .Net
Community on Github. (https://github.com/dotnet/core)
• Cross-platform; supporting Windows, macOS and Linux
• Compatible with .NET Framework, Xamarin and Mono, via the .NET Standard Library
• The C# and F# (VB is coming) can be used to write apps and libraries
• Flexible deployment with Docker support.
.Net Core
Mono vs .Net Core• .Net Core is not based on Mono.
• Mono supports a subset of the .NET Framework app-models (for example WinForms), .NET Core doesn’t support.
• Mono supports large subset .NET Framework APIs using same assemblies. .NET Core needs own compiled version.
• Mono is focused on mobile platforms in recent years, .NET Core is focused on cloud.
.Net Core
ASP.NET Core• No longer based on System.Web.dll. It is based on a set of granular and
well factored NuGet packages.
• Simply a console app that creates a web server in its Main method.
• Includes a managed cross-platform web server, called Kestrel, that you would typically run behind a production web server like IIS or nginx
• Doesn’t yet have some critical modules, such as WebSocket and SignalR

.Net Core
Limitations• Windows technologies such as WPF, WinForms not exist
• Some key features such as WebSocket, SignalR, Security not yet exist in ASP.NET Core. (in Roadmap)
• Reflection usage changed, old codes must be modified.
• App Domains, Remoting, Binary Serialization, Sandboxing not exist anymore.
