Convert xaml file to dll file

Continuing the discussion from Can I convert OpenRPA project to nuget package?:

Can you please guide how can I convert xaml file to dll file using OpenRPA code base

Just to make it clear. I sayed you can find the code needed inside the openrpa codebase, not that operpa has that functionality.
I do not want to support that over the forum, but I’m happy to tell you where you can find the code.

github.com

open-rpa/openrpa/blob/master/OpenRPA/DynamicActivityGenerator.cs

using OpenRPA.Interfaces;
using System;
using System.Activities;
using System.Activities.Presentation;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace OpenRPA
{
    public class DynamicActivityGenerator
    {
        private const string _templateTypePrefix = "";
        private AssemblyBuilder _ab;
        private ModuleBuilder _mb;
        private readonly string _fileName;

This file has been truncated. show original

As you can see, this also allows saving the workflow as a dll file ( and you can even add multiple workflows )
If you place that dll in the GAC or in the /Documents/OpenRPA/extensions folder, openrpa will load it, find the actions and add them to the toolbar.
You can also pack that dll into a nuget package and install it using the package manager in openrpa.

Another way, is to create a project that references openrpa.interfaces
Then create a class that inplements the iSnippet interface

github.com

open-rpa/openrpa/blob/master/OpenRPA.Interfaces/ISnippet.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace OpenRPA.Interfaces
{
    public interface ISnippet
    {
        string Name { get; }
        string Category { get; }
        string Xaml { get; }
        entity.snippet Snippet { get; set; }
    }
}

And then you embed the XAML in the class, this will let OpenRPA compile the xaml and then add the type to the Snippet toolbox
