From all different solutions for various problems I’ve implemented in the past I wanted to create a simple web application that I could get back to for reference any time, and this would be a fully working KnockoutJS web application. The idea was to implement a simple client contacts management application using .NET Core 1.1, Entity Framework Core 1.1, KnockoutJS, and MSTest + Jasmine for unit testing.
Recently I’ve been working on several small .NET Core web apps and was looking for two things. Firstly, a way to access Session in a data service directly, and not just by passing HttpContext reference down from controller. And secondly, log any unhandled exceptions that occur in the application. And the answer to both questions was IHttpContextAccessor interface!
Using RequireJS makes life easier injecting dependencies like data services into Knockout components. However, there is no direct way of unit testing calls to such data services and need a different approach to be able to create a jasmine mock for an injected data service.
Running microservices under HTTPS locally and in development environment with several domain names requires to have self-signed multi-domain SSL certificate. Also, starting from Google Chrome v58 SSL certificates are required to have SAN specified to avoid any SSL warnings. Luckily, there is a PowerShell script to make it quick and easy.
I needed to use the same C# enum in Knockout component view model to keep them both consistent. Also, this means less code duplication and no hardcoded values. The Knockout’s view model was in a component, therefore I decided to pass enum as a parameter from Razor view.
With the new Visual Studio 2017 out you might have been busy upgrading your .NET Core solutions to the new format and accidentally found out that StyleCop Analyzers stopped working? Automated upgrade will just upgrade projects, however will not adjust Visual Studio 2017 StyleCop Analyzers settings. Therefore, I’ve updated my template’s source code and added this quick guide.
Recently I cam across an issue when making HTTP DELETE or PUT requests to API would result in “405 method not allowed” error. After a quick research it turned out to be WebDAV component’s doing in IIS. Let’s re-create this issue locally, and learn how to solve it.
I was helping one old university project and as part of user experience and SEO tweaks we decided to move away from Facebook app comments to Disqus comments. The main reason was problems with comments/replies not appearing on the website, and on top of this we wanted to boost SEO having comments that could be indexed by search engines.
Sometimes you need to find database or tables sizes to find out what is taking the most disk space in a Microsoft SQL database server. Following two queries can be very handy in such case. Result looks following.
