I have learned about Workflow by dropping and clicking and the next phase is learn how to create WF with C# based this link (http://channel9.msdn.com/Series/Reimagine-SharePoint-Development/Translating-Custom-Code-Workflows-to-SharePoint-2013)

What material, link etc can you recommend me to learn about creating WF with C# coding? I have previous knowledge in ASP.net, regular c# coding etc but not in relation to WF with C# code.

Here is the good example to start with SP workflow using Visual studio.

Please follow the below steps:

1-Start with a Sequential Workflow. Start Visual Studio and create a new project from the template SharePoint --> Sequential Workflow.

2-In the next screen select the option Site Workflow.

3-In the next screen, leave the default option saying the user manually starts the Workflow.

4-Create Activity

What is an Activity?

A Workflow consists of a series of Activities. We can add Activities using the Toolbox. There are different types of Activities like Code Activity, SendEmail, etc.

5-Drag and drop a Code Activity from the toolbox.

6-Add code for the Activity, add code for this Activity. Double click on the codeActivity1

    private void codeActivity1_ExecuteCode(object sender, EventArgs e)
    {
    using (SPWeb web = SPContext.Current.Web)
    {
    SPList list = web.Lists["Manager"];
    foreach (SPListItem item in list.Items)
    {
        if (item["Address"] == null)
        {
            item["Address"] = "PLEASE SET THE ADDRESS!";

            item.Update();
        }
      }
     }
    }

7-Build and Deploy the Solution.

    You don't need to manually dispose SPWeb from SPContext.Current.Web – dbardakov Dec 27 '15 at 3:18
  • But , this will have problems when creating custom content types with aspx forms. how to create a custom approval form using the aspx pages / site pages? how to achieve these things? here is MVP Serge's blog about it :sergeluca.wordpress.com/2013/04/08/… also another thread discusses about this : sharepoint.stackexchange.com/questions/184624/… – userAZLogicApps Mar 13 '17 at 6:43
  • From MSDN: “Unlike previous versions, SharePoint 2013 does not support workflows that are scoped to a content type (SPContentType). However, the messaging infrastructure is extensible, so it can support any arbitrary scope. As a developer, you can set the EventSourceId property on a given WorkflowSubscription instance to any guid. You can then use that EventSourceId value to call PublishEvent(Guid, String, IDictionary<String, Object>), which triggers a new workflow instance of the specified WorkflowSubscription.”. I haven't found a workaround either. Case closed. – userAZLogicApps Mar 13 '17 at 6:46

There are basically two types of workflows we can create in Visual Studio:

  1. Sequential Workflow.
  2. State Machine Workflow.

Following articles gives you basic idea behind both WF:
