Load Runner .Net - Found an undefined object of type

Question

I am trying to record a .net thick client application (4.5.2) in Load Runner 12.01 but i am getting the following errors. can someone please help

namespace Script {
    using LoadRunner;
    using Mercury.LoadRunner.DotNetProtocol.Replay;
    using OM.EXIGO.SGUI;
    using OM.EXIGO.SGUI.WscServicesAPI;
    using OM.EXIGO.SGUI.WsCUsersAndRolesAPI;
    using Script.Accessors;
    using System;
    using System.Data;
    using System.Net;


    public partial class VuserClass {

        public virtual int Action() {

            AssemblyWithVersionDS_1 = new AssemblyWithVersionDS();
            lr.log("Event 5: AssemblyWithVersionDS_1.AssemblyWithVersionDT;");
            AssemblyWithVersionDTDataTable_1 = AssemblyWithVersionDS_1.AssemblyWithVersionDT;

            new DataSet_Accessor(AssemblyWithVersionDS_3).ReadXml(reader_1);

Here are the missing libraries that Load runner is complaining during compilation. *

// Found an undefined object of type System.Xml.XmlTextWriter. Assigning it the name writer_1.
// Found an undefined object of type OM.EXIGO.SGUI.WscServicesAPI.AssemblyWithVersionDS. Assigning it the name AssemblyWithVersionDS_2.
// Found an undefined object of type System.Xml.XmlTextReader. Assigning it the name reader_1.

I have added the dlls to csproj file and I got approx 1000 errors. Please let me know if you would like me to send few of the errors. How do I check whether I am using the right .net framework?

How can i resolve these errors?

Thanks Sri

You're using the .NET recorder! Good luck!

When you add a reference to a C# project there are two things to check:

The project references the dll.
The code references the namespace.

The XmlTextWriter and XmlTextReader objects are both part of the .NET framework and both live in the System.Xml namespace.

Check that your project has a reference to the System.Xml.dll file.

Add that namespace with a using statement:

using System.Xml;

The AssemplyWithVersionDS class looks to be third party. Its namespace is OM.EXIGO.SGUI.WscServiceAPI which you already have covered in a using statement. Check the namespace and class is there in the dll you referenced in your project. You can do this with a decompiler or the Visual Studio object explorer.

Unsolicited advice

The effort to understand the .NET recorder and its filter settings is probably equal, if not more, than the effort to understand your client application API with its server.

Learn that API and how the client uses it. Read the application source code. Ask developers to explain the source code.

Code the project yourself referencing that same API. You will be able to do it in much fewer lines of code than the recorder. It will be easier to understand and maintain.
