How do i initialise a property on a class in C# 6

Question

I have a class that uses some services. I need each service to be instantiated on creation of the class. In C# 6 I can see 2 ways of doing this but I'm not sure which would be correct...

protected static SomeServiceType Service => new SomeServiceType();

alternatively I could use an autoproperty initialiser...

protected static SomeServiceType Service { get;} = new SomeServiceType();

What are the advantages/drawbacks with each approach? Many thanks

You can try things out and see how it translates at http://tryroslyn.azurewebsites.net — Dennis_E, Dec 01 '15 at 14:21
@Andrey Ah, I see what you mean. It's valid C#, but it's not right for what Simon wants. My apologies. — Rawling, Dec 01 '15 at 14:34

I believe

the former ("Expression-bodied members") calls new SomeServiceType() every time the property is read
the latter ("Auto-property initializers") calls it once on instantiation, and returns the created instance every time the property is read.

It sounds like you want the latter.
