.NET Reunified – Microsoft’s Plans for .NET 5 (MSDN)

Mark Michaelis — Wed, 17 Jul 2019 17:36:53 +0000

When Microsoft announced .NET 5 at Microsoft Build 2019 in May, it marked an important step forward for developers working across desktop, Web, mobile, cloud and device platforms. In fact, .NET 5 is that rare platform update that unifies divergent frameworks, reduces code complexity and significantly advances cross-platform reach. This is no small task. Microsoft…

Essential .NET: Parse the Command Line with System.CommandLine (MSDN)

Mark Michaelis — Fri, 01 Mar 2019 22:54:13 +0000

Parsing the Command Line Going all the way back to. NET Framework 1.0, I’ve been astounded that there’s been no simple way for developers to parse the command line of their applications. Applications start execution from the Main method, but the arguments are passed in as an array (string[] args) with no differentiation between which…

Tuple Trouble: Why C# Tuples Get to Break Guidelines

Mark Michaelis — Fri, 01 Jun 2018 19:19:49 +0000

Trouble With Tuples Back in the August 2017 issue of MSDN Magazine I wrote an in-depth article on C# 7.0 and its support for tuples (msdn.com/magazine/mt493248). At the time I glossed over the fact that the tuple type introduced with C# 7.0 (internally of type ValueTuple<…>) breaks several guidelines of a well-structured value type, namely:…

Essential .NET: C# 8.0 and Nullable Reference Types

Mark Michaelis — Thu, 01 Feb 2018 20:23:16 +0000

Nullable Reference Types Overview Nullable reference types—what? Aren’t all reference types nullable? I love C# and I find the careful language design fantastic. Nonetheless, as it currently stands, and even after 7 versions of C#, we still don’t have a perfect language. By that I mean that while it’s reasonable to expect there will likely…

Essential .NET: C# 7.0 Tuples Explained

Mark Michaelis — Thu, 27 Jul 2017 20:16:56 +0000

Background Back in November, in the Connect() special issue of MSDN Magazine, I provided an overview of C# 7.0 in which I introduced tuples. Click here for the overview. In this blog I delve into tuples again, covering the full breadth of the syntax options. Why Tuples? On occasion, you’ll likely find it useful to…

Essential .NET: Custom Iterators with Yield

Mark Michaelis — Thu, 01 Jun 2017 19:39:33 +0000

Yield Return Statements In my last column, I delved into the details of how the C# foreach statement works under the covers, explaining how the C# compiler implements the foreach capabilities in Common Intermediate Language (CIL). I also briefly touched on the yield keyword with an example (see Figure 1), but little to no explanation.…

C# Foreach Internals and Custom Iterators With Yield

Mark Michaelis — Sat, 01 Apr 2017 21:39:40 +0000

Foreach Statement This month I’m going to explore the internals of a core construct of C# that we all program with frequently—the foreach statement. Given an understanding of the foreach internal behavior, you can then explore implementing the foreach collection interfaces using the yield statement, as I’ll explain. Although the foreach statement is easy to…

Essential MSBuild-A Build Engine Overview for .NET Tooling

Mark Michaelis — Sun, 01 Jan 2017 22:55:39 +0000

Exploring the .NET Core Build System Those of you who have been following .NET Core over the past few years (has it been that long?) know all too well that the “build system” has experienced a significant amount of flux, whether it be dropping built-in support for gulp or the demise of Project.json. For me…

Essential .NET: What’s New in C# 7.0

Mark Michaelis — Tue, 01 Nov 2016 22:56:41 +0000

Overview of C# 7 Back in December 2015, I discussed the designing of C# 7.0 (msdn.com/magazine/mt595758). A lot has changed over the last year, but the team is now buttoning down C# 7.0 development, and Visual Studio 2017 Release Candidate is implementing virtually all of the new features. (I say virtually because until Visual Studio…

Command-Line Processing With .NET Core 1.0

Mark Michaelis — Thu, 01 Sep 2016 16:22:32 +0000

Investigating .NET Core In this month’s Essential .NET column, I continue my investigation into the various features of .NET Core, this time with a fully released version (no longer in beta or a euphemistic release candidate). Specifically, I’m going to focus on its command-line utilities (which are found within the .NET Core Common library at…

Essential .NET: .NET Core Dependency Injection

Mark Michaelis — Wed, 04 May 2016 13:19:20 +0000

Understanding .NET Core Dependency Injection In my last two articles, Logging with .NET Core (bit.ly/1Vv3Q39) and Configuration with .NET Core (bit.ly/1OoqmkJ), I demonstrated how .NET Core functionality can be leveraged from both an ASP.NET Core project (project.json) as well as the more common .NET 4.6 C# project (*.csproj). In other words, taking advantage of the…

Essential .NET: Logging With .NET Core 1.0

Mark Michaelis — Thu, 07 Apr 2016 21:55:39 +0000

Exploring Microsoft.Extensions.Logging In the February issue, I delved into the new configuration API included in the newly named .NET Core 1.0 platform (see bit.ly/1OoqmkJ). (I assume most readers have heard about the recently renamed .NET Core 1.0, which was formerly referred to as .NET Core 5 and part of the ASP.NET 5 platform [see bit.ly/1Ooq7WI].)…

Essential .NET: Configuration in ASP.NET 5

Mark Michaelis — Thu, 04 Feb 2016 23:11:49 +0000

Understanding ASP.NET 5 Configuration Note: just prior to press time, Microsoft announced name changes to ASP.NET 5 and related stacks. ASP.NET 5 is now ASP.NET Core 1.0. Entity Framework (EF) 7 is now Entity Framework (EF) Core 1.0. The ASP.NET 5 and EF7 packages and namespaces will change, but otherwise the new nomenclature has no…

C# 6 Simplifies, Clarifies & Condenses Your Code

Mark Michaelis — Thu, 02 Jan 2014 00:25:06 +0000

Efficiently Code Using C# 6.0 C# 6.0 isn’t a radical revolution in C# programming. Unlike the introduction of generics in C# 2.0, C# 3.0 and its groundbreaking way to program collections with LlNQ, or the simplification of asynchronous programming patterns in C# 5.0, C# 6.0 isn’t going to transform development. That said, C# 6.0 will…
