Our instrumentation uses built-in extension mechanisms where possible, such as Django’s database instrumentation. But often libraries have no such mechanisms, so we resort to wrapping third party libraries’ functions with our own decorators. For example, we instrument jinja2 ’s Template.render() function with a decorator to measure template rendering time. We value the correctness of our instrumentation a lot so that we do not affect our users’ applications.
When something crashes in an app, fixing the bug is usually quite straightforward. But apps can also be blighted by bugs that don’t result in crashes, and this is where things start to get interesting. To find and fix these bugs, you will require as much information as possible and probably a combination of tools. Let me explain a process we know as ‘bug forensics’, based on a real bug that has impacted one of Bugfender’s customers.

The look and feel of the code and project files in .NET 5 would be the same, regardless of the type of app being created.
When you're evaluating a language for your next project, few things are more important than available third-party libraries and the package manager that ties them together.
