There are talks about this feature being postponed to a minor version after 8.0 is released, as it might not be ready for the major C# 8.0 release. The features for C# 8.0 still hasn’t been decided yet, so that means this information is still subject to change! Since Microsoft rebuilt the C# compiler into what is now the Roslyn compiler, the language teams’ feature implementation speed has been phenomenal, they are cranking features out in record time. Pro C# 7: With .NET and .NET Core Microsoft is committed to continuously update the C# language. They have even given us incremental updates of features that were not yet ready for the major versions release date and subsequently added it in minor language updates, such as C# 7.1, 7.2 and 7.3....
Recently a client called me about an issue where one of their production servers would run out of memory, every other week. The application in question was a .NET Framework 4.5 Windows service, that runs in an Azure VM, and ever so often it would become unstable and start causing trouble. I have previously helped this client set up an ELK stack, so it was quick for me to go into Kibana, look at metricbeat data, and see that their server indeed slowly was eating up memory over time. And every time the application was restarted, the memory would return to normal, and slowly creep upwards again. As you can clearly see, the application uses gradually more and more memory over time. Every time the line drops, was a restart...
As software consultants, we are often faced with bugs or problems the client cannot fix themselves. We are expected to quickly figure out the problem, and propose or implement a solution. Through my career I have developed a sort of mindset to get to the bottom of issues without wasting time hunting deadends or non-issues, and deliver results and value more efficiently. Here is my list of 10 tips for how I go about solving software problems 1. Focus A common problem I saw in myself, and I see very often in software developers, is a lack of focus. If you are trying to solve too many issues at once, you will probably fail at all of them. The first thing you must do, is figure out what you are...
At my current client, we have been dealing with an ongoing problem while scaling their cloud systems to the ever increasing customer-base. As it is with any software that needs to scale, we’ve been seeing and solving scalability problems along the way. Anyone who has ever dealt with scaling a system to accommodate a lot of concurrent users, knows that issues will be showing up places you aren’t expecting. While scaling the system, we’ve made it more resilient and fault tolerant, and also learned to mitigate many of the problems as they are arising. We’ve improved logging and metrics, so we know exactly what is happening, and can see stability problems before they affect the end-users. Redis loses connection, and will not reconnect In our system, we use StackExchange.Redis(v1.2.6) to...
I recently ran into a situation, where I needed to implement the same functionality, the same views and even the same tag-helpers for different customers. Like most other developers I hate copy-pasting code that should be shared across multiple projects. I had come across a similar need a few years back, but remembered that it was cumbersome in ASP.NET 3-5, to achieve this, and the solutions back then didn’t feel right. But since my recent switch to dotnet core, I knew there was a chance that Microsoft had a prepared an early christmas present for me. So I started researching my options, searching for titles similar to this blog post, and finally found a solution on the third place on google (Yes I was that desperate). Introducing Application Parts /...
Finally, I created the blog. My old website on this same domain, was a static html file, telling people who I was, and what I do. Not only was that 3 years out of date, and I had since changed jobs, and become a consultant. But it provided no value for anyone. Like most other developers, I run into problems and find solutions to those problems, but I am not sharing that knowledge with the world, which is a shame. Through my career I have functioned as a tutor and then later a teacher at the local academy, but I often find myself in mentoring positions, such as the one I am in now. I currently work as a Senior Software Consultant, and one of my many duties, is...
