As a refresher, the Windows code base is approximately 3.5M files and, when checked in to a Git repo, results in a repo of about 300GB .  

In my previous posts, I wrote about mapping your current skills, and using this knowledge to decide which skill you should learn next as a software developer. 

The consolidated repositories are going to be about .NET 5 and going forward. It will not be possible to build .NET Core 3.1 or earlier from these repositories. 

Agenda

1. C# 11 Initial Triage
   1. Generic attributes
   2. field keyword
   3. List patterns
   4. Static abstracts in interfaces
   5. Declarations under or patterns
   6. Records and initialization
   7. Discriminated unions
   8. Params Span<T>
   9. Statements as expressions
   10. Expression trees
   11. Type system extensions
    

Now you can upload .mp4 and .mov files in issues, pull requests, discussions, and more. 

The ASP.NET Core tag helpers improve on the HTML templated helpers in ASP.NET MVC 5. ASP.NET Core comes with some useful stock tag helpers for common tasks such as creating custom elements or extending existing HTML elements, but their use can be extended to making a framework such as Bootstrap easier to work with. Dino shows how helpers are used, and demonstrates a Bootstrap Modal Tag Helper 

ASP.NET Core 1.0 is the ground-up rewrite of ASP.NET, MVC and Web API, bringing a new paradigm in building web applications and APIs in .NET. With this rewrite brought new techniques in building SOLID applications, and updated some existing patterns and tools.
In this session, we'll take a lap around some of the major extension points of ASP.NET Core 1.0, walking through how these features can help us build cleaner, more maintainable systems. We'll cover web APIs, traditional MVC applications, controllers, views, filters, dependency injection, tag helpers and more. With a SOLID foundation, our ASP.NET Core applications will be dead simple to build and maintain.
