Question: When I use Resharper's Code-Cleanup, this is what it does to my backing fields...

`[DebuggerBrowsable(DebuggerBrowsableState.Never)] private readonly DateTime_auctionOn;`

^ all on a single line.

How can I tell R# that I want it to be formatted like this:

```
[DebuggerBrowsable(DebuggerBrowsableState.Never)]
private readonly DateTime _auctionOn;

```

please.

with cherries on top.

Answer: 
Look under `Code Editing > C# > Formatting Style > Line Breaks and Wrapping` in the options and take a look at the following entries. specifically this one: `Place field attribute on same line`

Goto Resharper Options → `Code Editing` → `Code Cleanup` and now you need to add your own Code Cleanup profile (as MyProfile in screen shot) and set rules as you required, and save the profile. (**Keep Un-check Reformat Code**)

One thing more, you need to select your custom profile while cleanup
