Practical tips and best practices

As we navigate the nuances of functional programming in C# and its approach to handling nulls, some practical strategies emerge. These strategies ensure that our applications remain robust while benefiting from the enhanced clarity and predictability that functional paradigms provide.

Strategies for migrating existing code bases to adopt nullable reference types and Option

Let’s consider strategies for migrating your existing code bases to adopt nullable reference types and Option:

• Incremental adoption: Instead of overhauling the entire code base, start by enabling nullable reference types in specific areas or projects. This can be achieved using the #nullable enable directive:

  #nullable enable
  // The section of the code where nullable reference types are enabled.
  #nullable restore

• Use of analysis tools: Tools such as Roslyn analyzers (https://docs.microsoft.com/en-us/visualstudio/code-quality/roslyn-analyzers-overview) can help...
