ASP.NET Core: How log filtering works

Logging infrastructure of ASP.NET Core supports logs filtering that is useful when we need one logging configuration for development environment and the another for live environment by example. This blog post introduces log filtering in ASP.NET Core through simple dummy controller code samples.

Building simple plug-ins system for ASP.NET Core

Recently I built plug-ins support to my TemperatureStation IoT solution web site. The code for .NET Core is different from what we have seen on full .NET Framework (application domains etc) but there’s still nothing complex. This blog post describes how to build simple plug-ins support to ASP.NET Core web application.

Defensive logging on ASP.NET Core

ASP.NET Core logging framework is intelligent one and it supports also so called defensive logging that helps us to have intelligent logs but still avoid putting additonal load to system when it’s not needed. This blog post is short overview of defensive logging on ASP.NET Core.

File logging on ASP.NET Core

ASP.NET Core introduces new framework level logging system. Although it is feature-rich it is not complex to use and it provides decent abstractions that fit well with the architecture of most web applications. This blog post shows how to set up and use file logging using framework-level dependency injection.

Paging with Entity Framework Core

Paging query results is timeless topic and some days ago I got question about how to do it with Entity Framework Core. Using my previous work on paging I wrote some simple extension methods that work with IEnumerable and IQueryable interfaces. There’s also method that maps entities to models.

Command-line ASP.NET Core development on Linux

Although command-line is not so popular thing in Windows world it has more love by developers in Linux world. In the light of .NET Core and ASP.NET Core that run also on Linux, developers from Linux world want to know if they can also develop ASP.NET Core applications using simple command-line tools. Here is my overview about how to develop, build and run ASP.NET Core applications on Linux command-line.

Running Visual Studio Code on Linux

For my up-coming presentation “ASP.NET Core on Linux” I need Linux VM I can access with Remote Desktop to run Visual Studio Code. After hours of different problems that grew fast over my head I was able to make things work and now I have functioning VM I can use for demos. This post is short overview about what I did and it is for those readers who also want to have Linux VM with Visual Studio Code.

ASP.NET Core: Using third-party DI/IoC containers

Although ASP.NET Core has built-in dependency injection and inversion of control support it is still possible to use DI components by other vendors. ASP.NET Core supports other containers through simple IServiceProvider interface. This blog post explains how to use other containers with ASP.NET Core and shows how to use Structuremap and Autofac with framework level dependency injection.

TemperatureStation: My Windows 10 IoT Core solution on Github

I published to Github sample temperature measuring solution that runs on Windows 10 IoT Core and that is built on Visual Studio. Source code with basic documentation is available too. This demo project is there to give some starting point to those who are visiting my Brewing Eisbock with Raspberry PI and Windows 10 IoT sessions in different conferences.

Running ASP.NET Core applications on IIS

Preparing for CodeCamp Cluj 2016 I needed to host one ASP.NET Core application on IIS web server. I had one simple box with clean IIS available in my network and I installed my ASP.NET Core application on it. This blog post is simple step by step guide showing how to prepare and configure IIS for ASP.NET Core applications.

ASP.NET Core: Using view injection

Besides all other dependency injection forms, ASP.NET Core supports also view injection. Yes, it is possible to inject instances directly to views and there’s no need to update view models to carry information that is already available through dependency injection. This blog post demonstrates how to use view injection.

Creating minimal ASP.NET Core web application

By its nature ASP.NET Core application is .NET Core command-line application with some web sites stuff that is set up when application starts. Although Visual Studio has ASP.NET Core web site template that comes with simple default web site and start-up class it’s possible to be even more minimal. This blog post introduces the minimal ASP.NET Core web application.

Using xUnit with ASP.NET Core

Writing tests for ASP.NET Core applications can be done using xUnit. xUnit works on both.NET Framework and .NET Core. This post shows how to set up and use xUnit with ASP.NET Core applications in Visual Studio and on command-line. Targeting multiple frameworks is also covered.

ASP.NET MVC: Precompiling views

This blog post is about how to really precompile ASP.NET MVC views. It destroys the myth about MvcBuildViews as precompilation tool and shows you how to configure precompiling. It also stops on some internals of precompiling and explains what are the options and limitations with it. There is also real-life example for Azure where precompiling of views may avoid some serious headaches that one may face otherwise.

This year again I have honour to speak at TechDays 2016 Netherlands. It is well organized event with very good and interesting content. I was speaking there year ago and I had only good experiences with this event. This year it is held in RAI Center at Amsterdam in the beginning of October – 04-05.10.2016. This blog post tells why it is important to visit this event and why it is important to come to my Azure deep-dive session.

Using dependency injection with view components

On ASP.NET Core view components support dependency injection. We can use some DI/IoC container but we can also go with framework level dependency injection. This blog post explains how dependency injection works with view components and as an example I show you some code I’m using to build top menu for my demo site.

Building Pager view component

Whenever we deal with data we need some mechanism for paging it. It makes it easier for users to navigate through data and same time we don’t put too much load to our systems. This blog post shows you how to build pager for your MVC site using ViewComponent and PagedResult class.

Dependency injection in ASP.NET 5

ASP.NET 5 has dependcy injection available at framework level and ASP.NET 5 makes heavy use of it. Most of things surrounding controllers, views and other MVC components are implemented as services that web applications consume. This post is quick overview of dependency injection in ASP.NET 5 with some examples.

ASP.NET 5 and CSS bundling: Fixing image paths

With ASP.NET 5 we don’t have current bundling and minification system available. It’s replaced by new one that is based on Gulp. Default web application shows how to minify simple and safe files. But if you have some more complex design with CSS files referring to images then you are on your own. This post shows you how to solve a problem.

What is ASP.NET console application?

One mystery in ASP.NET 5 that people are asking me about are ASP.NET 5 console applications. We have web applications running on some web server – what is the point of new type of command-line applications that refer by name to web framework? Here’s my explanation.
