C# 14 is Here

C# 14 ships with .NET 10 and introduces several features that clean up common patterns.

The `field` Keyword

Auto-properties can now access their backing field without declaring it:

public string Name
{
    get;
    set => field = value.Trim();
}

Implicit Span Conversions

Better Span and ReadOnlySpan handling reduces allocations in hot paths.

Params Collections

params now works with any collection type, not just arrays:

void Log(params IEnumerable<string> messages) { }

Conclusion

C# 14 continues the language's trend toward concise, expressive code. Upgrade your projects and start using these features today.
