Windows Workflow Foundation 3


workflow failed validation when dynamically adding a custom activity to parent custom activity


 
Hello all,
 
I developed  a parent custom activity  to which child custom activities like send email, sms ..etc have added in the same workflow activity library and been using where ever required and it worked fine.
 
Now, My requirement is changed like I don't want to add the child custom activities code directly in the parent custom activity but to add a reference whenever a new child activities comes like file log custom activities and also for the existing custom activities( Send email, Send sms). But when I did that its giving the error message "Workflow validation failed".
 
The new custom activities should add like a plugin to the existing parent custom activity.
 
Could anyone have suggestions.
 
 
 
What is the validation error? Can you give some more details about the error message and stack trace?
