You can use the LogonAs method to connect to Microsoft Dynamics AX to implement a customized .NET-connected application. This example uses the LogonAs method to connect to the AOS using a specified proxy user account.

Starting the AOS

In this section, you will ensure that the AOS status is Started.

To start the AOS

Click the Start menu, point at Administrative Tools, and then click Services.
In the Services window, in the right pane find the AOS, the default install name is Microsoft Dynamics AX Object Server 6.0$01-MicrosoftDynamicsAX. Check the Status, it should be Started. If not, right-click Microsoft Dynamics AX Object Server 6.0$01-MicrosoftDynamicsAX and then click Start.

Setting up the Proxy User

This example assumes that you have created a user to set up as a proxy user or you will use your own user ID, domain, and password. Microsoft Dynamics AX is not supported to run without a domain controller. In this section you will set up the proxy user.

To set up the proxy user

From the navigation pane, click System administration > Setup > System > System service accounts.
In the Business connector proxy area, enter the same user ID credentials that you will specify in the code. Fill in the alias with the user ID and the network domain that has a fully qualified domain name that the user ID is a part of.

Creating a Project

In this section, you will create a Windows application that will access data in Microsoft Dynamics AX.

To create a project

Open Visual Studio.
From the File menu, click New, and then click Project to display the New Project dialog box.
In the Project types pane, click Visual C#. In the Templates pane, click Windows Forms Application.
Set the name to LogonAsExample.
To change the location of the solution directory, click Browse and specify a new location.
Click OK.

Adding a Button to a Form

You can add controls to the form by dragging them from the toolbox. In this example, you will add a button to the form which will be used to log on to Microsoft Dynamics AX.

To create the layout a form

In the Toolbox, double-click the Button control to add it to the form.

Adding a Reference to .NET Business Connector

This example assumes that you have a project in which you want to access Microsoft Dynamics AX data. You must create a connection using .NET Business Connector. In this section, you will add a reference to the .NET Business Connector assembly.

To add a reference to .NET Business Connector

In Solution Explorer, right-click References, and then click Add Reference.
In the Add Reference window, click the Browse tab.
Specify the location of Microsoft.Dynamics.BusinessConnectorNet.dll, and then click Add.

Note

For a typical install, the assembly is located at C:\Program Files (x86)\Microsoft Dynamics AX\60\Client\Bin\.
Click OK.

To set the project target framework

In Solution Explorer, right-click your application project, and then click Properties.
In the Application tab, set the Target framework to .NET Framework 4.

To update the application configuration settings

In Solution Explorer, double-click the app.config file and update the following configuration settings.
```
<startup useLegacyV2RuntimeActivationPolicy=”true”>
<supportedRuntime version “v4.0” />
```
On the File menu, click Save app.config.

Note

When you build your project, the development environment automatically creates a copy of your app.config file, changes its file name so that it has the same file name as your executable, and then moves the new .config file in the bin directory.

If you do not update the app.config file, you will get the following error:

“Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.”

Adding Code Behind the Form

In this section, you will use the LogonAs method to connect to Microsoft Dynamics AX on behalf of a specific user. This example specifies the proxy user. You will use a hard-coded string for the ProxyUserID and password that match the proxy that you specified in the Business Connector proxy.

To add code behind the form

On the form, double-click button1 to access the LogonAsExample.Form1 code.
Add the following using statement to the LogonAsExample.Form1 form.

    using Microsoft.Dynamics.BusinessConnectorNet;

Add the following code on the click event of the button control.

    private void button1_Click(object sender, EventArgs e)
    {
        // Create an instance of the Axapta class.
        Axapta DynAx = new Axapta();
    
        // Add the proxy user.
        // Replace the ProxyUserID and password parameters with the 
        // proxy user name and password that you specified
        // in the Business Connector Proxy.
        System.Net.NetworkCredential nc = new System.Net.NetworkCredential("ProxyUserID", "password");
        string strUserName = "ProxyUserID";
    
        // Test the connection to the .NET Business Connector.
        try
        {
            DynAx.LogonAs(strUserName.Trim(), "", nc, "", "", "", "");
            MessageBox.Show("Success");
            DynAx.Logoff();
            MessageBox.Show("Logoff completed.");
    
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.ToString());
            MessageBox.Show(ex.Message);
        }
    }

Press F5 to run the application.
On the form, click button1. The message box displays Success. Click OK. The message box displays Logoff completed.
