ReSharper 4.5 Released!

After expanding its functionality in previous releases, ReSharper 4.5 shifts focus to the issues of performance and memory usage. Making the tool agile, robust and responsive – and a bit smarter still – is the main idea behind ReSharper 4.5.

Read about the improvements and enhancements below or watch this Flash demo.

  • Performance and memory consumption: When working on large solutions, you will feel a great deal of difference between ReSharper 4.0 and 4.5.
  • New solution-wide warnings and suggestions: Analyze usage of non-private types and type members within your whole solution (or don’t!).
  • Visual Basic 9 support: ReSharper’s cross-language refactorings and editing experience enhancements now support VB9 code.
  • Improved setup for naming conventions, which are now supported by all ReSharper features.
  • New Inline Field refactoring and enhancements in existing refactorings.
  • Go to Implementation: Go from the usage of a class or method straight to its implementation, bypassing its declaration.

Download your free 30-day trial of ReSharper 4.5.

Upgrades from ReSharper 4.0 are free.

    Very helpful, still can’t use it with large solutions though. ‘Out of memory exception’ pops up all the time.

    Sweet! But it is nearly unusable due to out-of-memory on solutions that worked for years – now we cannot even do the simplest things, e.g. refactoring, with them.

    Yes, it is completely unusable because of OutOfMemory exception. I think we will have to cancel our licence and try to get refund if it’s possible :/

    Good plugin (expecially for a previous IntelliJ IDEA user) but the ReShaper crashes VS2008 with Out of memory exception all the time.

    I agree, the OutOfMemory exceptions are making resharper entirely unusable

    What a great tool to increase programmer productivity.

    I agree with the last posts. I am tired of OutOfMemory popping out all the time when modifying ASPX files in code view mode. I use to download the nightly builds to see if there is any fix available, but nothing yet.

    I was able to address the OutOfMemory problems by enabling LARGEADDRESSAWARE in devenv.exe ( However, in what I consider to be a medium solution (5 class libraries, 1 web project: approx 1000 files) and Code Analysis is so slow (specially in 500+ line files) that I had to disable it to be productive.

    This major performance issue aside, this is an awesome plug-in…ctrl+click and ctrl+shift+n (open file) are great time savers.
