ReSharper 8 EAP, Build 3: What’s New!

Dmitri Nesteruk

You have probably already guessed that this post is about a new set of features that has appeared in the new build of the ReSharper EAP late last week, so, without further ado, here’s what we’ve got in store for you:

Bulb Menus in Margin

In an attempt to streamline the programmer’s interaction with gutter marks and bulb pop-ups, we have added an option to merge both of these constructs into a single construct that we call an action indicator. Here’s what it looks like:

As you can see, both the gutter mark options from unit tests and the context action on that element have been merged into a single menu. The use of action indicators is an optional feature that can be found in ReSharper’s Options under Environment|Editor|Editor Appearance:

Option #2 in the above list revers to the R#7.1-style mechanism of showing a bulb pop-up. The last option prevents any visual queues that a bulb item is available (save for the indicator itself), and only shows the menu when you explicitly open it with Alt+Enter.

Please note that this feature is available only for Visual Studio 2010 and later.

Decompiler Improvements

We’ve already talked a bit about decompilation (both in ReSharper and dotPeek), but this deserves a mention: we now know how to correctly decompile

• async methods and await expressions, including async lambdas.

• Expression trees — the decompiler will now help you when exporting Linq to SQL or Entity Framework code in query expressions. This means in ReSharper 7 you could only decompile an expression into this:
  
  whereas with ReSharper 8 you can decompile it into this:
  

• Field-like events, taking into account the lock-free nature of C# 4’s add/remove accessors.

Fix in Scope

In-place fixes are great, but what’s even better is when you can apply that fix in a given scope. Take those pesky unused references, for example – now you can get rid of them not only in a file, but also on a project/solution level. All with a single quick-fix:

Now quite a few fixes can be applied to a larger scope than just the code under the cursor — including making a field read-only or removing a redundant cast.

Default Alignment Setting Adjustments

One common complaint about ReSharper’s default settings was that certain constructs we indented, shall we say, aggressively. The two particular cases of note are anonymous lambdas

And another case is indentation when a function call including parameters gets too big and is indented similar to

These and similar cases will now be treated more gently by ReSharper’s default settings.

Code Inspection Performance Improvements

Last, but certainly not least, after another round of performance improvements we’ve managed to once again speed up ReSharper’s code analysis. Specifically, the Find Code Issues command enjoys an over 2× performance improvement.

Now, you know what to do – grab the EAP and check out those features today!
