How to Prevent ReSharper from Wrapping One-Line Statements?

Update for newer versions of ReSharper

(my version is 2021.1)

Since a picture is worth than a thousand words, you probably want to configure it like so. In this way it takes care of constructs such as using too:

Check the ones that start with Keep existing arrangement [...] if you want to instruct ReSharper to leave, say, single-line ifs alone if they are already written that way.

Took me longer to figure out than I wanted it to, hopefully it will help someone else.

You can change this in the R# Settings:

1. Open the menu Resharper -> Options
2. Go to Code Editing -> C# -> Formatting Style -> Line Breaks and Wrapping
3. Change to option Break line in single embedded statement to Put on a single line or Do not change

Edit: As mentioned by @Alexander it would be more suitable to use the option Break Line in a block with a single statement which I think is available since R# 8
