Tutorial :Workflow 4.0 Argument Errors



Question:

I'm having two errors with workflow, one I think is caused by a bug in the compling with VS2010, its

Error 1 Could not resolve attachable member {clr-namespace:;}Flowchart1.requestType C:\Documents and Settings\Hilliard\my documents\visual studio 10\Projects\WorkflowConsoleApplication1\WorkflowConsoleApplication1\Flowchart1.xaml WorkflowConsoleApplication1

That error usually goes away after two builds in a row. I don't know if its related but another error gets thrown once the workflow runs in the Partial Class in the new

"Cannot set unknown Member 'requestType'. Line:3 Offset:4".

Anyone have any clue if I'm doing something wrong here? I just want to pass in two parameters into my workflow and use them throughout the workflow. Right now the workflow won't even load as them defiend in the workflow.


Solution:1

It's hard to tell this information from your description, I think you really need to add more details: -how are you declaring requestType? -how are you passing the arguments in to your workflow? -what is the XAML you are getting the compile error from?

You could also try asking your question on the MS forum for WF 4.0 Beta1... http://social.msdn.microsoft.com/Forums/en-US/wfprerelease/threads


Solution:2

by that "{clr-namespace:;}" you have in your error message, i suspect you're refering to some class within your current assembly (say a custom activity or a type from within your compiling assembly).

if that's the case, then simply go ahead with splitting your assembly, and moving your custom activities and/or types (which are referenced by your workflow instance) into the new one.
