Gotcha with .globalconfig and Visual Studio
VS will always apply a `.globalconfig`, not just when analyzers are activated like the CLI build does. Use a different name and explicit inclusion to get consistent behavior.
Fun with generics: mapping a generic instance from a non-generic reference
DDD can lead to dealing with non-generic references to generic instances of types. Generically mapping these instances or generically calling code with them is not straightforward. I present how it can nonetheless be unobtrusively achieved with a general visitor-like pattern.
Advanced MSBuild: project file as single source of truth for build and runtime
It is possible to define build parameters in a way that is accessible at runtime by declaring custom AssemblyAttribute entries in your csproj file.
Fun with generics: building a generic call without reflection
DDD can lead to generic types that are hard to import to. This technique can be used to make a generic call with multiple type arguments when each type argument is supplied individually, e. g. from an import into a domain model.
Advanced MSBuild: Introduction
Knowing MSBuild can help you remove code duplication, enforce consistency in a large repo and improve developer experience.
The pain of using Excel files for user input
In 2022, reading Excel files in C# is still a pain and can require intricate knowledge of XLSX, even when using a library like NPOI.
Just for fun: changing runtime behavior with unreachable code
Unreachable code can still change compiler behavior and thus runtime method behavior. An example with `yield`.
Be more productive with more keystrokes: use named Regex capture groups
Use named capture groups when parsing with regular expressions to make the Regex self-contained and the matching code more readable.
Nuget Packaging Series 2: Beware of DLL version conflicts
Putting assemblies with different TFMs in the same nuget package can lead to runtime assembly loading errors because of transitive assembly reference version conflicts.
Closed Type Hierarchies with records … NOT!
TL;DR: You cannot create closed type hierarchies with record types because of the generated protected copy constructor.
