Workflow problems on CRM 3.0 with .Net framework 2.0

If you have .Net framework 2.0 or higher it can adversely affect the Workflow engine. This can give one or more of the following problems:

1. Workflow rules do not run (errors can be found in the event log, pointing you at workflow monitor, but nothing useful can be found in workflow monitor)
2. Bulk import operations never go beyond pending, even though the workflow service is running
3. When starting Workflow Manager on the CRM server you get an error message 'Workflow Manager cannot start...configuration file is corrupted'
4. You cannot attach to the CrmWorkflowService to debug workflow assemblies with Visual Studio .Net 2003

This can be because the Crm Workflow Service is running with the 'wrong' version of the .Net Framework. To correct this, create a text file with the following (case-sensitive) text:

<configuration>
<startup>
<supportedRuntime version="v1.1.4322"/>
</startup>
</configuration>

Save the file as CrmWorkflowService.exe.config in the \Microsoft CRM\Server\bin directory. Then restart the CRM Workflow Service.
