From time to time, I see that some of the workflows goes to suspended state and in Suspension Reason column, I see the error about updating the entities (WF uses EF).What&#8217;s my concern is, is there a way to make the host writes inner exception together with suspension reason?Thanks in advance<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/i.msdn.microsoft.com\/dn186180.LOGO_Win1211(id-id,MSDN.10).png\" \/><br \/>\nmsdn<br \/>\nnet-framework-forums windows-workflow-foundation<br \/>\nI have a long running workflow which never gets resumed to the last persisted point when I try to resume the workflow after it gets suspended due to an unhandledexception.At the root of my workflow I use persist activity to create a persist point. Followed by this is the root try catch block.In my catch block I&#8217;m rethrowing the exception and I have added WorkflowUnhandledExceptionBehavior to the workflow service host with the action set to &#8220;AbandonAndSuspend&#8221;.I have also\u00a0added the<\/li>\n<li><img decoding=\"async\" src=\"http:\/\/i.msdn.microsoft.com\/dn186180.LOGO_Win1211(id-id,MSDN.10).png\" \/><br \/>\nmsdn<br \/>\nnet-framework-forums windows-workflow-foundation<br \/>\nI might miss something obvious, but how do I catch unhandled exceptions in a workflow running in WorkflowServiceHost? WorkflowInstance has an OnUnhandledException property, WorkflowServiceHost does not. Why not? I might try to evaluate tracking events to detect exceptions, but I think there must be an easier way.

We have configured the unhandled exception behavior to be &#8220;AbandonAndSuspend&#8221;, which suspend any workflow instances going into error. We have noticed that sometimes suspendedworkflow instances are automatically resumed by the WorkflowServiceHost (without our intervention). Wethink it happens sometimes when we restart the IIS pool, but we currently can not reproduce this constantly.Is this a normal behavior<\/li>\n<\/ul>\n<p id=\"rop\"><small>Originally posted 2013-11-27 12:24:22. <\/small><\/p>","protected":false},"excerpt":{"rendered":"<p>msdn net-framework-forums windows-workflow-foundation Hi All,\u00a0I want the cancel currently running workflow.How can I achieve this?I have tried using following code but I am not able to cancelled currently running workflow.\u00a0CancellationTokenSource cts = new CancellationTokenSource();\u00a0WorkflowApplication wfApplication = new WorkflowApplication( new TestWorkflow())cts.Token.Register(() =&gt; { wfApplication.Cancel(); });Now I have created cutom Activity for cancel this workflow.\u00a0public sealed class [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1649","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/posts\/1649","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/comments?post=1649"}],"version-history":[{"count":0,"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/posts\/1649\/revisions"}],"wp:attachment":[{"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/media?parent=1649"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/categories?post=1649"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unknownerror.org\/index.php\/wp-json\/wp\/v2\/tags?post=1649"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
