Workflow Foundation (WF) error related to performance counters

[petersunnet]

Is Workflow Foundation (WF)supported?

When calling workflowRuntime.StartRuntime(), I gotthis error:


Cannot continue the current operation, the performance counters memory mapping has been corrupted.

I found the following online and tried it, but it didn't work for me.

Did anybody make WF work? Anyspecific changes needed?

Thanks.

Hi,
Did you make any headway with this?
Haven't done anything with it yet myself but thought you might find this helpful:

I think the solution is to turn off performance counters in the app, since I doubt you'll be able to use this feature anyway because it probably requires administrative priviledges.

Thanks Mark and Aristotle.

I tried turning off perf counters again using a different approach and it was a success.

For the benefit of all, could you share with us how you turned the performance counters off?
I am running into the same problem, and the MSDN web.config method isn't working.

Thanks.

I figured it out. Here's a working config that disables performance counters and enables persistence:

web.config:
[quote]

<configuration>
....
<configSections>
....
<sectionname='PersistentWorkflowConfig'type='System .Workflow.Runtime.Configuration.WorkflowRuntimeSec tion,System.Workflow.Runtime,Version=3.0.00000.0,C ulture=neutral,PublicKeyToken=31bf3856ad364e35'/>
</configSections>
</configuration>
....
<PersistentWorkflowConfigEnablePerformanceCounters= 'False'>
<CommonParameters>
<addname='ConnectionString'value='DataSource=sql2k5 01.discountasp.net...###remainderofconnectionstrin g###'/>
</CommonParameters>
<Services>
<addtype='System.Workflow.Runtime.Hosting.SqlWorkfl owPersistenceService,
System.Workflow.Runtime,Version=3.0.00000.0,Cultur e=neutral,PublicKeyToken=31bf3856ad364e35'
UnloadOnIdle='true'/>
</Services>
</PersistentWorkflowConfig>

</CODE>

global.asax:
[quote]

voidApplication_Start(objectsender,EventArgse)
{
WorkflowRuntimeworkflowRuntime=newWorkflowRuntime( 'PersistentWorkflowConfig');
workflowRuntime.StartRuntime();
Application['WorkflowRuntime']=workflowRuntime;
}

</CODE>
