Consider factors like project age, budget, and effort when deciding whether to implement modern features in new or existing codebases.

#7about 3 minutes

How to stay current with C# development

Follow Microsoft documentation, community creators like Nick Chapsas, and experiment with preview builds to keep up with annual C# releases.

#8about 2 minutes
