I have developed a Project Server 2010 workflow which is working intermittently. When it fails, the following error message appears in ULS:
Load Workflow Assembly: System.IO.FileNotFoundException: Could not load file or assembly 'IWU.ProjectWorkflow.Generic, Version=1.0.1.0, Culture=neutral, PublicKeyToken=b8bb096e7d86dd60' or one of its dependencies. The system cannot find the file specified. File name: 'IWU.ProjectWorkflow.Generic, Version=1.0.1.0, Culture=neutral, PublicKeyToken=b8bb096e7d86dd60'
I installed the workflow using the Install-PJWorkflow PowerShell script fromhttp://msdn.microsoft.com/en-us/library/office/ff459292(v=office.14).aspx. I've confirmed that the assembly is installed in the GAC (and have removed and redeployed the solution multiple times), but the version number in the error message is incorrect. The DLL in the GAC is version 1.1.17.0 and in my Elements.XML file the strong name of the assembly is:
"IWU.ProjectWorkflow.Generic, Version=1.1.17.0, Culture=neutral, PublicKeyToken=b8bb096e7d86dd60"
Why would the version number be different in the error message? Is that information cached somewhere? And why would it work sometimes and not others?
Thanks in advance for any help you can provide!
