I have a weird problem... I'm trying to deploy a sharepoint solution in production. This project works fine in the test environment, but in production trying to enable the feature returns this error:

Enable-SPFeature : Could not load file or assembly 'YYYYY, Version=, Culture=neutral, PublicKeyToken=a7a65c9275aa3510' or one of its dependencies. The system cannot find the file specified.
At line:1 char:17
+ Enable-SPFeature <<<<  -Identity ApprovazioneCommesse_ApprovazioneCommesse -Url "https://ZZZ.XXXXXX.org/sites/KKK"
+ CategoryInfo          : InvalidData: (Microsoft.Share...etEnableFeature:   SPCmdletEnableFeature) [Enable-SPFeature], FileNotFoundException
+ FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletEnableFeature

But I know the file is there. The really weird thing is that I can enable the same feature via web (site settings>site collection features> Enable)

How is it possible?

I ran into similar errors quite often in the past when code has been developed without taking into account that a PowerShell script doesn't provide a valid HTTP/SharePoint context.

Most likely your feature assembly contains code which calls SPContext.Current, e.g. SPContext.Current.Web, or SPContext.Current.Site, or similar functions which are not available if you don't have a SharePoint website context.

Same applies BTW if you want to read/write to the SharePoint WebApplication web.config file using the System.Web.Configuration.WebConfigurationManager class.

  • I'll check if this is the case, still I can't understand why I would work in the test environment and not in production (both activated via PowerShell) Apr 5, 2013 at 15:04
  • In this case make sure all the resources you use in your code are accessible on the production machine. Sounds like there's something blocked.
