Why does Code analysis differ between Cassini and IIS Express?

Question

We're moving to use IIS Express instead of Cassini and I noticed that Code Analysis isn't returning the same results. On one site we have where we started using code analysis late in the game the results are 423 warnings with Cassini VS. 6 warnings With IIS Express.

Interestingly, on a default VB ASP.NET Web Site without any modifications, the results are 49 warnings with Cassini VS. 0 warnings With IIS Express.

Can someone please explain this.

ISSUE REPRODUCTION:

1. Open Visual Studio 2010
2. Create a new "VB - ASP.NET Web Site" (not a WebApp)
3. Run code analysis for website (File Menu -> Analyze -> Run Code Analysis on Web Site)note that output shows: Running Code Analysis on Web Site C:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop\FxCopCmd.exe /o:"\[OurServer]\sys\user[MyUserName]\My Documents\Visual Studio 2010\Projects\AllLocalTest\AllLocalTest{38557EBD-D900-482B-B048-B527347036D1}\CodeAnalysisLog.xml" /asp /searchgac /ignoreinvalidtargets /forceoutput /successfile /ignoregeneratedcode /outputCulture:"1033" /r:"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop\Rules" /rs:"=MinimumRecommendedRules.ruleset" /rsd:"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Team Tools\Static Analysis Tools\FxCop..\Rule Sets" /f:"C:\Users[MyUserName]\AppData\Local\Temp\tmp94D6.tmp.cadir\bin\App_global.asax.dll" /f:"C:\Users[MyUserName]\AppData\Local\Temp\tmp94D6.tmp.cadir\bin\App_Web_303a5ti3.dll" /f:"C:\Users[MyUserName]\AppData\Local\Temp\tmp94D6.tmp.cadir\bin\App_Web_bwgrez5a.dll" /f:"C:\Users[MyUserName]\AppData\Local\Temp\tmp94D6.tmp.cadir\bin\App_Web_ruojygvq.dll")
4. Results have 0 errors and 49 warnings
5. change site to use IIS Express (right-click in solution explorer on path and select “Use IIS Express…” )accept popups and wait for solution explorer to change path to “http://localhost...”
6. Run code analysis for website (File Menu -> Analyze -> Run Code Analysis on Web Site)note that output shows nothing related to FxCop
7. Results have 0 errors and 0 warnings

Hi daustin_dev,

I try to check it in my PC, it seems that it worked normally, it has the same warnings.

Just to make this issue clearly, did you install the VS2010 SP1? VS 2010 SP1 supports both IIS Express and Cassini (VS 2010 supports only Cassini). Maybe you could try to check it in other PC.

Best Regards,

Thanks for the reply, Jack.

We have tried it on multiple machines with the same results. It’s only the same if we create a “Web Project”. The issue exists when a “WebSite” is created. Which did you try?

Answer 3

Hi daustin_dev,

I check it with a web project, would you mind sharing us your project? I try to check it in my PC. Of course, if you have the VS2012, maybe you could try to check it in the latest version.

Please attach your Visual Studio project, you can upload it to the sky driver, and then share the download link in your post.

Best Regards,

Answer 4

I’ve created a zip file of the site for you. Please see the ReadMe.txt file in the root.

The site is nothing but a default “ASP.NET web site” via “Visual Studio Ultimate -> File -> New Web Site…” (Shift + Alt + N)

Answer 5

Hi daustin_dev,

I’m afraid that I misunderstand this issue, actually I try to check it with the web app, not the web site, in addition, I use the “Local IIS Web server”, not the IIS Express, and I think you install it like the following screen shot.

I try to repro it with a web site, I get the same issue, it doesn’t work, I’m not very familiar with the IIS express, but when we run the Code analysis tool for a web site, we could get the “Running Code Analysis on Web Site” in the Output window, but if we use the IIS Express, we couldn’t get it in the window. So I’m afraid that it doesn’t support it.

Code analysis for managed code analyzes managed assemblies and reports information about the assemblies, I doubt that if we use the IIS Express, it couldn’t start the Code analysis.

Maybe you could submit a feature request: http://visualstudio.uservoice.com/forums/121579-visual-studio. The Visual Studio product team is listening to user voice there. You can send your idea there and people can vote. Thanks for your understanding.

Best Regards,
