For the last 5 years I posed at least one post per week. I like to take a moment to celebrate this milestone and look back on how I did this and what I learned in doing so.
The NDC 2017 had a long-lasting effect on me. Especially the presentation by Troy Hunt on "Hack Your Career" gave me the motivation to blog more and showed me a way to do it.
Since a few people had troubles with creating the .well-known folder for the security.txt in ASP.Net, I will explain in this post how you can do it in .Net 4.8 and .Net 6.
Your web application is under the constant thread of hackers. It does not matter if you have a small pet project application on the internet or a big commercial site. As soon as it is accessible from the internet, someone will attack it.
Sometimes we get lucky, and someone finds a security issue and wants to report it. But where should they report it to? The address [email protected] may be processed by someone without any knowledge of IT or security and ignores the report.
If you need to block an IP address, you can do that directly in IIS 10 with the Web IP Security feature. You can install it with this PowerShell command (run it as administrator):
After a long time, I am back at an annoying problem with Visual Studio. One ASP.Net application works when I start it through "With Debugging", but it fails when I try "Run Without Debugging":
In NUnit we can use the category attribute to classify tests. This allows us to mark long running tests and then tell our test runner to run them on demand but not with the regular test run. All we need to do is to add a category to a single test (or a class):
While refactoring the folder structure of a project I run into something strange. Git suddenly stopped to track a few files and marked them as deleted. That was not my intention then those files are needed. How can we fix this?
One of the most important ideas of agile software development is for me the short feedback cycle. Instead of working for weeks or even months at a problem on our own, we try to get feedback as fast as we can. That not only works with user stories; we can apply this idea to every task independently of its size.
I experienced a great example of this principle a few weeks ago. Using this example, I would like to give you an idea of how to put a principle into action. For the sake of brevity, I am using the format of a PAR statement (problem, action, result).
Of all the (programming) languages you can learn, I think SQL is the one that will help you the most throughout your career as a software developer. If you know the basics of SQL, you can solve set based problems directly in your database without writing a ton of code to do the same in an imperative way. And your applications will run much faster if they only fetch the data you really need.
Sometimes Visual Studio is strange. As I tried to disable a StyleCop rule in Visual Studio 2022, I got this error:
