Elsa 2 - Custom activity error

Hello,

I copied/pasted the code from the documentation and I have the following error :

The code is from : https://elsa-workflows.github.io/elsa-core/docs/extensibility/extensibility-custom-activities#hello-world-activity

I think the problem may come from this sentence that says I have to implement the OnExecute method but I do not know how.

Implement/override the OnExecute/OnExecuteAsync and if necessary the OnResume/OnResumeAsync methods.

What you can do is create a class library where you define all of your activity classes, e.g. MyActivity1 and MyActivity2. Then all you need to do is take one of these class names, e.g. MyActivity1 and do the following:

services.AddElsa(elsaOptions => elsaOptions.AddActivitiesFrom<MyActivity1>());

That will register both MyActivity1 and MyActivity2 (and any other activities you may have present in your class library).
