Initializing field by default value is redundant

Can I really and truly trust .NET to initialize fields (like ints, structs and the like)? And what if I still want to initialize those fields - what could be the repercussions?

The C# specification states on p.305 (17.4.4)

The initial value of a field, whether it be a static field or an instance field, is the default value (§12.2) of the field’s type. It is not possible to observe the value of a field before this default initialization has occurred, and a field is thus never “uninitialized”.

Yes, you can really trust .NET to initialize fields to their default values. There are basically no repercussions for doing it explicitly. (One small caveat here: if you initialize static fields explicitly, then anyone running the type initializer a second time via reflection will end up re-initializing those fields. This is a real corner case though!)

Do whatever promotes the most readability in your particular codebase.
