C# Is this initialiser really redundant?

Question

I have the following line of code:

var dmrReceived = new DownloadMessagesReport();

StyleCop and ReSharper are suggesting I remove the redun

If it's a field, it will be automatically initialised to its default value - null for a reference type. Given the var however, I'm guessing it's not, and that you're actually instantiating it further down in your code anyway, thereby discarding the value you have instantiated here. You don't need to initialise a variable where it's declared. If you want to use var you do, but then I'd recommend you declare it where you actually first use it.
