How to use C# await in Custom Workflow Activity.

Scenario: I am creating a record and then retrieve a related record of the one I've just created using QueryExpression and filtering by the id of the record I've just created. I want to await the creation of the record until the QueryExpression finds the related record.

My bad, actually it's a web service. The Web service receives data outside of crm then updates an entity field, that then triggers a crm workflow which then creates a related record. Now the web service waits for the workflow to trigger and create the record, once it is created, the web service returns a response with data from the created related record.

Hi ,

You can use await async in custom workflow, there is no bound to use c# functionality inside custom workflow.

You can refer below url -

Hope this helps

Good luck.

Is your create and querying done in the same custom workflow activity?

RE: Use C# await in Custom Workflow Activity

Currently, I check if the returned EntityCollection has any entity...if not, the thread sleeps for 2 seconds and tries again (3 times) in a for loop. If still no entities, it returns a message, else takes the first record in EntityCollection.

Any better way of doing this?
