I'm using Visual Studio 2012, created a web-service that add/select data from Microsoft axapta 2009, when trying to add data I get the following error

Could not load file or assembly 'Microsoft.Dynamics.BusinessConnectorNet, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Could not load file or assembly

I've tried changing the project type to only x86 output and changed IIS server app pool settings to only x86. nothing worked for me

After searching for almost a week for a solution. the answer was in removing the reference of the connector from the front-end project and copying the business's connector to bin folder

This particular webapplication required the IIS to run in 64 bit mode and therefore this was changed. The Microsoft.DynamicsBusinessConnectorNet.dll that I was using was the 32bit version – which ofcourse was the cause of the error.

The solution was to enable the application pool to allow 32 bit application at IIS. This is done by:

  • Right clicking the application pool and selecting “advanced setting”

  • Set the “enable 32-bit applicataions” to true
