VSTTExecution failure. by aractnido

Same here. A plethora of VSTTExecution and VSTTAgentProcess errors. Right now I can't run any regression or unit tests because I'm not sure if my latest changes are bad or if it's just the (putrid) QTAgent32.exe barfing on the rug.

Microsoft Visual Studio 2010
Version 10.0.30319.1 RTMRel
Microsoft .NET Framework
Version 4.0.30319 RTMRel

81 error messages from VSTTExecution in 5 days. The content is one of the following:

"(devenv.exe, PID 1196, Thread 42) OutOfProcessStrategy.ProcessMonitorThread: Agent process was shut down unexpectedly; will attempt to restart."

"(devenv.exe, PID 3556, Thread 1) StringToVariantHelper.WriteSafeArrayToVariant: Failed to clear the variant. Exception message: Bad variable type. (Exception from HRESULT: 0x80020008 (DISP_E_BADVARTYPE))."

Comment: I did actually experience some really wird behaviour related to Console.WriteLine and the Test Result Details window one day.

I too am experiencing this problem exactly the same as zen.... There must be some workaround?!

Pretty much the same thing here for me (498 errors in the event log in the last 7 days) so I thought I'd post my error message. I hope it helps.

The description for Event ID 0 from source VSTTExecution cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

(devenv.exe, PID 12844, Thread 1) HierarchyOutputCollection.GetOutputGroup: either buildManager.FindActiveProjectCfg or projectCfg[0].OpenOutputGroup failed: System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

at System.Runtime.InteropServices.Marshal.ThrowExceptionForHR(Int32 errorCode)
at Microsoft.VisualStudio.TestTools.Vsip.HierarchyOutputCollection.GetOutputGroup(IServiceProvider serviceProvider, IVsHierarchy hierarchy)


the message resource is present but the message is not found in the string/message table

I concur, this is still an issue and should be re-evaluated.

Please re-open. I'm seeing the same error in the event log after updgrading a test project from VS 2008 to VS 2010 and running my tests:

Microsoft Visual Studio 2010
Version 10.0.30319.1 RTMRel

the message resource is present but the message is not found in the string/message table

I too am getting a sea of red in my event log from VS2010 (version 10.0.30319.1 RTMRel).

Why has this been closed?

I can reproduce this at will. Any workarounds? Suggestions? This is a hard bug... not intermittent.

1. Create a WCF data service
2. Put an context name from a EF model in the DataService template field
3. Right click .svc file and "Run in Browser"

Watch the failure.... every time.

Hello,

We were unable to repro the exception that you saw in the latest bits. We have added lines to our code just to make sure this does not happen again.

Thanks for your feedback,
Visual Studio Product Team

We have asked the product unit who works on that specific feature area to review this issue. As mentioned in the invitation email and on the connect site, due to the volume and timeframe of the LCTP. Teams will be triaging these issues as though they are internal bugs/suggestions and will not be responding to individual issues.
