delete the files, not the folder itself.

Re: IIS7.5 restart MVC3 application when delete subdir

I need to know, why it works so. As i see for in couple of articles and docs - that it allowed to create and delete subfolders for mvc3 application

If you put under bin, that the application restarts ( asp.net behaviour, not mvc only)

But, as a caution, I will do delete only the files

Re: IIS7.5 restart MVC3 application when delete subdir

But I do not put it under bin directory. And I should have such directory for each customer. so it could be hundreds of empty folders. So it's quite bad solution.

Re: IIS7.5 restart MVC3 application when delete subdir

put under App_Data.

Does it restart?

Re: IIS7.5 restart MVC3 application when delete subdir

Yes. It restarts. But if I do not delete folder all works fine.

I was unable to reproduce this.

Re: IIS7.5 restart MVC3 application when delete subdir

Actually I couldnt reproduce your senario, so I just could tell you the general reason why the application domain recycle.

Machine.Config, Web.Config or Global.asax are modified
The bin directory or its contents is modified
The number of re-compilations (aspx, ascx or asax) exceeds the limit specified by the <compilation numRecompilesBeforeAppRestart=/> setting in machine.config or web.config (by default this is set to 15)
The physical path of the virtual directory is modified
The CAS policy is modified
The web service is restarted
Application Sub-Directories are deleted (see Todds blog http://blogs.msdn.com/toddca/archive/2006/07/17/668412.aspx for more info)

Hope this helpful
