The author shares their experience switching to primary constructors for ASP.NET Core services, explaining the key pitfall: parameters are captured as mutable variables, not readonly fields, meaning accidental reassignment compiles without warning. The recommended approach is to use primary constructors freely in DI service classes where accidental reassignment is unlikely, but fall back to traditional constructors for validation-heavy types, multiple constructor overloads, or classes with too many dependencies. 53 4 [See all Milan Jovanović archives](/sources/milanjovanovic/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/milanjovanovic/best-of/2026/04#page","url":"https://daily.dev/sources/milanjovanovic/best-of/2026/04","name":"Best Milan Jovanović Posts — April 2026","description":"The most upvoted Milan Jovanović posts from April 2026, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/milanjovanovic/best-of/2026/04#items","numberOfItems":1,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/why-i-switched-to-primary-constructors-for-di-in-c--ctodiijms","name":"Why I Switched to Primary Constructors for DI in C#"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Milan Jovanović","item":"https://daily.dev/sources/milanjovanovic"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/milanjovanovic/best-of"},{"@type":"ListItem","position":5,"name":"April 2026"}]}]} ```
