Miruna, 

Sorry for posting an incorrect script, we noticed that error and corrected it, below is the code my coworker made with the correction:

LFApplication app = new LFApplication();
           LFServer serv = (LFServer)app.GetServerByName("localhost");
           LFDatabase db = (LFDatabase)serv.GetDatabaseByName("Aplicom-Procesos");
           LFConnection conn = new LFConnection();
           conn.UserName = "admin";
           conn.Password = "123";
           conn.Create(db);
           
           IDocumentContents doc1 = (IDocumentContents)db.GetEntryByID(130);
           
           
           
           DocumentExporter docuExport = new DocumentExporter();
           
           PageRange Range = new PageRange(1, 1);
           PageSet Set = new PageSet(Range);
           
           docuExport.ExportPdf(doc1, Set, PdfExportOptions.None, "C:\\Esteban\\doc.pdf");
           
           doc1.Dispose();

Any suggestion? We are missing something important. 

As Miruna said, you are mixing RA with LFSO. You will want to use "DocumentInfo" class which implements "IDocumentContents" interface. This code should get you in the right direction:

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using Laserfiche.DocumentServices;

    /// <summary>
    /// Provides one or more methods that can be run when the workflow scripting activity is performed.
    /// </summary>
    public class Script1 : RAScriptClass91
    {
        /// <summary>
        /// This method is run when the activity is performed.
        /// </summary>
        protected override void Execute()
        {
            // Write your code here. The BoundEntryInfo property will access the entry, RASession will get the Repository Access session
            using (DocumentInfo doc = Document.GetDocumentInfo(BoundEntryId, RASession)) //or use Document.GetDocument([Path], RASession) if you know the path
            {
                PageSet pg = doc.AllPages;
                DocumentExporter docexp = new DocumentExporter();
                docexp.ExportPdf(doc,pg,PdfExportOptions.None, "C:\\Ricardo\\doc.pdf");
            }
        }
    }

Now this assumes that in your workflow you have a bound entry you are running the script against.

We trying with this code  but it shows the following error

"No entry point was found" any idea?

If you want to use it that way, use this code: (Make sure that entryid exists in Laserfiche as well)

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using Laserfiche.DocumentServices;

    /// <summary>
    /// Provides one or more methods that can be run when the workflow scripting activity is performed.
    /// </summary>
    public class Script1 : RAScriptClass91
    {
        /// <summary>
        /// This method is run when the activity is performed.
        /// </summary>
        protected override void Execute()
        {
            // Write your code here. The BoundEntryInfo property will access the entry, RASession will get the Repository Access session
            using (DocumentInfo doc = new DocumentInfo(130, RASession))
            {
                PageSet pg = doc.AllPages;
                DocumentExporter docexp = new DocumentExporter();
                docexp.ExportPdf(doc,pg,PdfExportOptions.None, "C:\\Ricardo\\doc.pdf");
            }
        }
    }

Also, it is not necessary that you create a new session. Workflow creates the session in the object "RASession" which uses the workflow connection profile.

it shows this error

it can't find this document

Any idea?

I'm confused, your screenshots and code keep switching between WF 9.1 and 9.2.

When exactly are you getting those errors? If it's when you test the script, did you specify an entry? The Error List in the script editor should give you the line where the error occurs.

We are trying to export a tif image to pdf, any idea of how to export this document with Laserfiche SDK?

Umm... I'm confused

this is the script we are testing

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Data.SqlClient;
    using System.Text;
    using Laserfiche.RepositoryAccess;
    using Laserfiche.DocumentServices;

    public class Script1 : RAScriptClass92
    {
        protected override void Execute()
        {
            using (DocumentInfo doc = Document.GetDocumentInfo(272, RASession))
            {
               
                MsgBox(doc.Name);

                DocumentExporter docexp = new DocumentExporter();

                docexp.ExportPdf(doc, doc.AllPages   ,PdfExportOptions.None, "C:\\Esteban\\doc.pdf");
            }
        }
    }

and is shows this error
