I am using .NET 4.0 with IronRuby to invoke some methods on WatiN framework 2.0.10.928. I keep getting the following error when loading the WatiN assemblies: C:\Projects\IronRubyDemo\IronRubyDemoSolution\BusinessObjects\>ir -S spec testacc ountbalanceUI.rb C:/IronRuby/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:30:in `require': A n attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so thi s load may be dangerous. If this load is not intended to sandbox the assembly, p lease enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlin k/?LinkId=155569 for more information. (LoadError) from C:/IronRuby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:30:in`require’ So, I went to the App.config file of my project and added the following lines: \ I tried running it again and encountered the same problem. Any ideas! ---

Your app is not the thing trying to load that assembly, IronRuby is. So, you’ll need to add that to IronRuby’s app.config. That said, why are you trying to load an assembly from a network location in your tests? That is, IMO bad testing practice. – Will G. [http://hotgazpacho.org/](http://hotgazpacho.org/) ---

I guess it should be in the installed folder of IronRuby. Also, I am just loading an assembly from my local machine. ---

Thanks for the help! I edited the IronRuby configuration file and now the error has disappeared. ---

## wherever you installed ironruby. it’s called ir.exe.config for me in C:\ironruby\bin Met vriendelijke groeten - Best regards - Salutations Ivan Porto C. ---

I created a new project in Visual Studio 2008 and tried running the same code and it worked without any problems. It did not gave me load error for the Interop.SHDocVw.dll. Looks like there are some issues with WatiN when using it on .NET 4.0 framework. ---

Actually facing the same problem on VS 2008. ---

Got the first problem solved by editing the configuration file. Now, facing problem loading the Interop.SHDocVw assembly. Here is the complete code: require ‘rubygems’ require ‘spec’ require File.dirname( **FILE** ) + ‘/bin/Debug/BusinessObjects.dll’ require File.dirname( **FILE** ) + ‘/bin/Debug/WatiN.Core.dll’ require File.dirname( **FILE** ) + ‘/bin/Debug/Microsoft.mshtml.dll’ require File.dirname( **FILE** ) + ‘/bin/Debug/Interop.SHDocVw.dll’ include BusinessObjects include WatiN describe Account, “when something happens” do before do IE = WatiN::Core::IE @ie = IE.new end it “should do something” do end end And here is the error: C:\Projects\IronRubyDemo\IronRubyDemoSolution\BusinessObjects\>ir -S spec testacc ountbalanceUI.rb F 1. Errno::ENOENT in ‘BusinessObjects::Account when something happens should do some thing’ Could not load file or assembly ‘Interop.SHDocVw, Version=1.1.0.0, Culture=neutr al, PublicKeyToken=db7cfd3acb5ad44e’ or one of its dependencies. The system cann ot find the file specified. ./testaccountbalanceUI.rb:18: Finished in 0.148009 seconds 1 example, 1 failure ---

instead of requiring the files with path. maybe try to set the load path $:.unshift( File.dirname( **FILE** ) + “/bin/Debug”) require ‘BusinessObjects.dll’ require ‘WatiN.Core.dll’ require ‘Microsoft.mshtml.dll’ require ‘Interop.SHDocVw.dll’ ## I also think that the last 2 are redundant.. they should get picked up automatically by Watin.Core isn’t it Met vriendelijke groeten - Best regards - Salutations Ivan Porto C.

It should be loaded automatically but for some reason it is not.

The load path basically determines where ir.exe looks for assemblies and files to load. if you do $LOAD\_PATH.unshift(File.dirname( **FILE** ) +"/bin/Debug") and then require Watin.Core.dll the CLR knows where to look for your DLL’s including the referenced assemblies You might have gotten a correct result by including your assemblies in the inverted order too So either you do : $LOAD\_PATH.unshift(File.dirname( **FILE** ) +"/bin/Debug") require ‘BusinessObjects.dll’ require ‘WatiN.Core.dll’ or this might work too: require File.dirname( **FILE** ) +"/bin/Debug/Interop.SHDocVw.dll" require File.dirname( **FILE** ) +"/bin/Debug/Microsoft.mshtml.dll" require File.dirname( **FILE** ) +"/bin/Debug/BusinessObjects.dll" require File.dirname( **FILE** ) +"/bin/Debug/WatiN.Core.dll" * * * Met vriendelijke groeten - Best regards - Salutations Ivan Porto C. ---

Why is it different? I mean why does it not work when I include the path and why does it work when I set the load path?
