The two of you who have been following this blog regularly probably know that I’ve tried demos of JetBrains ReSharper versions 3 and 4 in the past.  The verdict was that they were pretty neat, but far too slow to be of any practical use.

Today I downloaded the trial version of ReSharper 4.5.  The big improvement they claim to have made is a significant speed increase.  After trying it out, I believe it.  They claim speed increases of about 25-40% depending on the type of project you’re working on, but that’s an understatement.  I’m using the same hardware I used for the previous test a year ago (yeah I need an upgrade, but that’s not something I care to address right now).   I haven’t used stopwatch tests, but it feels like ReSharper 4.5 is easily two to three times faster than ReSharper 4.0.

It’s now totally worth using — it has all of the benefits without any of the drawbacks the previous versions had.  Good work, JetBrains.

Microsoft has this neat little program, BizSpark, that gives a company free access to pretty much all of their products for three years for a total of $100.  The idea is that if they can get startups hooked on Microsoft operating systems, databases, and development tools, then if the companies are still alive after three years they’ll become thriving, paying customers.

Seems like a smart idea to me.  After all, startups generally have to be run “on the cheap”, so most of them turn to Linux and open source solutions.  BizSpark is keeping Microsoft competitive, helping out startups, and is an all-around good thing.

So, my company, Zeta Centauri, Inc., was just accepted into the BizSpark program and I now have access to all these neat development tools, including Visual Studio 2008 Team Suite (which is $10k retail).  It’s still downloading, but I’m sure I’ll have to post about some of the bells and whistles that come with it.  I’ve never worked with anything above Visual Studio Professional.   With any luck these new and shiny tools will help me build something awesome.

Last year I tried the Resharper 3 plugin for Visual Studio, and posted my thoughts on it:

http://basternae.org/blog/2007/07/26/jetbrains-resharper/

It was OK, but not all that special. It had potential, but wasn’t quite “there” yet.

I just finished trying out Resharper 4.0 and you could paste the Resharper 3.0 review in its place. It’s neat, but not so neat that it’s a ‘must have’ utility. The features added in the latest version really aren’t anything I find useful — I don’t refactor Visual Basic, don’t use LINQ, etc.

It does, however, appear to run a little faster than version 3.  That might just be the system I’m using it with, but the slowness is no longer an annoyance.

I’ll keep my eye on it. Maybe they’ll add something I can’t live without in a later version.

Since VS2008 somewhat rudely decided that it would become the default application for all projects, including projects that were VS2005 projects (what exactly *is* the Visual Studio Version Selector good for, anyway?), I decided to try building Basternae with 2008.

It was actually a pretty painless process.

Something changes in every version of a compiler and 99% of the time something breaks, either due to deprecation, changes in the way warnings and errors are treated, or most often due to changes in dependencies and the way they are handled. In any project of significantly large size, you can expect errors when converting to a new version of Visual Studio.

It was no surprise when the project didn’t build. It was, however, a pleasant surprise. It found three bad cast operations that shouldn’t have been written in the first place, the sort of thing that VS2005 should have complained about but didn’t. After spending a few seconds fixing those, everything built fine with no problems.

Visual C++ projects are a different story. You see, I’m convinced that Microsoft hates Visual C++ and just wants it to shrivel up and die. As long as Visual Basic and Visual C# projects are healthy, it’s safe to release a new version of Visual Studio. This time it was a bit of DLL hell along the lines of missing MSVCP90D.DLL and MSVCP90.DLL errors when trying to run a newly-built executable. WTF? Weren’t those installed with Visual Studio? You mean we can build C++ projects but aren’t allowed to run them?

OK, OK, so maybe it was a missing runtime redistributable. That’s fair enough and something I could live with since that’s the way .NET works. So I download the Microsoft Visual C++ 2008 Redistributable and install it. Fail. Epic fail.

After an unsuccessful Google search (plenty of people with the problem but no clear solution) I went playing with some of the project settings. The final fix was setting “Generate Manifest” to “Yes” instead of “No” in the Linker->Manifest File section.

Today was the Microsoft “launch event” for Visual Studio and Server 2008. I attended the local presentation and walked away with a free copy of Vista Ultimate and Visual Studio 2008. It was free to attend and I got $600 worth of software out of the deal. How can you beat that? Sure the presentations weren’t very relevant to the types of development I do (all they talked about were database-driven development, MS Office add-in development, and ASP.NET web development, all of which I don’t have any involvement in.)

I may or may not switch development of Basternae 3 to VS2008 right away and probably won’t start using Vista until my next PC upgrade, but it still feels nice to get free stuff.

I just finished a trial of JetBrains ReSharper 3.0, an add-on for Visual Studio 2005 designed for code analysis and refactoring.

ReSharper’s main feature is automatic code analysis. When you open a code file, it will scan for and higlight errors in your code and show an error count and error locations on the sidebar. It also goes a step further than the compiler by highlighting warnings and making suggestions for improving code.

For many errors, it will pop up a lightbulb icon if it knows how to fix the problem. If you click this icon, it will give you a menu that will let you perform a quick-fix.

ReSharper is smart enough to warn about places where a NullReferenceException could occur and overrides intellisense with its own, more thorough version. It gives more parameter information, shows more class info, and takes intellisense to the next level in general.

Visual Studio’s refactoring options are a neat addition, but not overwhelmingly useful. ReSharper extends them quite a bit to add a lot more functionality. I never really made much use of ReSharper’s refactorings since I prefer to change things by hand.

ReSharper has quite a few features that I couldn’t imagine ever using, such as code generation, code templates, and build script editing.

Although it add a lot of features and functionality to Visual Studio, in a project of any significant size (such as the 116k-line Basternae codebase) it causes a drastic slowdown, rendering my development machine nearly unusable at times, especially when code analysis is grinding away on a large code file. It’s true that the codebase I’m working on isn’t optimal (huge classes, bloated files, plenty of errors, etc), but that’s why I’m working on it in the first place — to fix all of that.

It’s an ambitious tool, but perhaps it’s trying to do too much. Maybe future versions will be faster, but right now it doesn’t add enough value to the development process to justify the $149 price tag.

If JetBrains removed everything but the code analysis functions for a “lite” version that sold for $49 I’d buy it in a heartbeat, but as it is now ReSharper doesn’t speed up my development process more than it slows it down. I’ll look at the 4.0 version when it comes out, but 3.0 isn’t for me.

I mentioned in an earlier post that Visual Studio 2005 was gradually becoming more responsive as the error count decreased.

On my system, which is a Pentium D 2.66 GHz with 1GB of RAM, it starts becoming usable again at about 22,000 errors (we’re at 22,267 now).  That’s where the “type-a-character-and-wait” transitions into using the application in realtime.

One thing to keep in mind is that I have a trial installation of ReSharper (which I’ll post about once I’ve had more chance to evaluate), which slows things down considerably due to constant recompiling to find errors in realtime and excessive intellisense-ing above and beyond that which Visual Studio does.  Without Resharper I think I would have noticed responsiveness a bit earlier, but for now I have to say that 22,000 errors should be considered the upper limit of usability in a system like mine.

With more RAM it would probably be a bit better, and at this point it probably makes sense to upgrade to 2GB (RAM’s gone down quite a bit recently, probably due to Vista finally starting to sell).  I’ll have to add that to my grocery list.
