Past, present and future of C# and .NET
Kathleen Dollard Director of Engineering, ROICode [email protected] Coding: 2 Advanced: 2
“In the beginning there was…” Take a look back at over 15 years of .NET and C# evolution and look into the future driven by enormous underlying changes. Those changes are driven by a shift in perception of how .NET fits into the Microsoft ecosystem. You’ll leave understanding how to leverage the .NET Full Framework, .NET Core 1.0, .NET Standard at the right time. Changes in .NET paralleled changes in the languages we’ll reflect on how far C# and Visual Basic have come and how they’ve weathered major changes in how we think about code. Looking to the future, you’ll see both the impact of functional approaches and areas where C# probably won’t go. The story would not be complete without cruising through adjacent libraries – the venerable ASP.NET and rock-star Entity Framework that’s recovered so well from its troubled childhood. You’ll leave this talk with a better understanding of the tool you’re using today, and how it’s changing to keep you relevant in a constantly morphing world. Coding: 2 Advanced: 2

Project Rider Xamarin Xamarin Mono forms .NET Standard
The .NET Standard Library is a formal specification of .NET APIs that are intended to be available on all .NET runtimes. The motivation behind the Standard Library is establishing greater uniformity in the .NET ecosystem. ECMA 335 continues to establish uniformity for .NET runtime behavior, but there is no similar spec for the .NET Base Class Libraries (BCL) for .NET library implementations. Standards
• ECMA 334 – C# (2002/2003 with updates) • ECMA 335 – CLI (2001/2003 with updates) • Rotor (shared source) implemented 334/335 no longer relevant • ECMA 372 = C++/CLI
.NET Standard (not yet an ECMA standard) (Will there be a .NET Standard Standard?) .NET Standard
• Formal specification • “of .NET APIs that are intended to be available on all .NET runtimes” • Provides uniformity in the .NET ecosystem • Let’s your code to run anywhere • 335 is for CLI, this is for BCL • Let’s you produce portable libraries • Not same as Portable Class Libraries • Reduce/eliminate need for conditional compilation for OS https://weblog.west-wind.com/posts/2016/Nov/23/NET- Standard-20-Making-Sense-of-NET-Again Standard libraries implement at least .NET Standard What is does it take to develop?
