Blazor: Running C# in Frontend (cross-browser)

Blazor is a framework that allows you to code C# for frontend. Github page.

An experimental web UI framework using C#/Razor and HTML, running client-side via WebAssembly

The arrival of WebAssembly creates the possibility of building client-side web applications using languages and runtimes that are more typically used for native app development. Blazor runs .NET code in the browser via a small, portable .NET runtime called DotNetAnywhere (DNA) compiled to WebAssembly.

The programming model will be familiar to anyone who’s worked with Razor (the C#/HTML page format used by ASP.NET MVC and ASP.NET Pages).

Blazor makes your app compact and much faster since it is compiled into code the browser doesn’t have to parse.

It can run on older browsers (ex IE11) because it has polyfills.

The only note here is that it is very early. I mean, it is so early it can’t even be called alpha or anything. It is just an experiment at the moment. (Post written at 2017-08-12)

What’s new in C# 7.0

Project roslyn is bringing good news. A lot of new features are coming up and you can check the status on GitHub (not all features are guaranteed to make it in time).

I created a GitHub project – brunolm/csharp-features to show what is coming and how to use it.

The new ASP.NET Core 1.0

ASP.NET 5 is dead, now it is called ASP.NET Core 1.0.

• ASP.NET 5 is now ASP.NET Core 1.0
• .NET Core 5 is now .NET Core 1.0
• Entity Framework 7 is now Entity Framework Core 1.0

It is not yet officially released, they don’t have a date yet but they said they won’t take just a month but they won’t take years. You can use it today in production if you want to, but as it is not done yet some things could break, be renamed…
