You can access the SharePoint project service in the following types of solutions:

An extension of the SharePoint project system, such as a project extension, project item extension, or project item type definition. For more information about these types of extensions, see Extend the SharePoint project system.
An extension of the SharePoint Connections node in Server Explorer. For more information about these types of extensions, see Extend the SharePoint connections node in Server Explorer.
Another type of Visual Studio extension, such as a VSPackage.

Retrieve the service in project system extensions

In any extension of the SharePoint project system, you can access the project service by using the ProjectService property of an ISharePointProject object.

You can also retrieve the project service by using the following procedures.

To retrieve the service in a project extension

In your implementation of the ISharePointProjectExtension interface, locate the Initialize method.

Use the projectService parameter to access the service.

The following code example demonstrates how to use the project service to write a message to the Output window and Error List window in a simple project extension.

<Export(GetType(ISharePointProjectExtension))> _
Friend Class GetServiceInProject
    Implements ISharePointProjectExtension

    Private Sub Initialize(ByVal projectService As ISharePointProjectService) _
        Implements ISharePointProjectExtension.Initialize
        projectService.Logger.WriteLine("This message was written by using the " & _
            "project service in a project extension.", LogCategory.Message)
    End Sub
End Class

[Export(typeof(ISharePointProjectExtension))]
internal class GetServiceInProject : ISharePointProjectExtension
{
    public void Initialize(ISharePointProjectService projectService)
    {
        projectService.Logger.WriteLine("This message was written by using the " +
            "project service in a project extension.", LogCategory.Message);
    }
}

For more information about creating project extensions, see How to: Create a SharePoint project extension.

To retrieve the service in a project item extension

In your implementation of the ISharePointProjectItemTypeExtension interface, locate the Initialize method.

Use the ProjectService property of the projectItemType parameter to retrieve the service.

The following code example demonstrates how to use the project service to write a message to the Output window and Error List window in a simple extension of the List Definition project item.

<Export(GetType(ISharePointProjectItemTypeExtension))> _
<SharePointProjectItemType("Microsoft.VisualStudio.SharePoint.ListDefinition")> _
Friend Class GetServiceInProjectItem
    Implements ISharePointProjectItemTypeExtension

    Private Sub Initialize(ByVal projectItemType As ISharePointProjectItemType) _
        Implements ISharePointProjectItemTypeExtension.Initialize
        projectItemType.ProjectService.Logger.WriteLine("This message was written " & _
            "by using the project service in an extension for the ListDefinition project item.", _
            LogCategory.Message)
    End Sub
End Class

[Export(typeof(ISharePointProjectItemTypeExtension))]
[SharePointProjectItemType("Microsoft.VisualStudio.SharePoint.ListDefinition")]
internal class GetServiceInProjectItem : ISharePointProjectItemTypeExtension
{
    public void Initialize(ISharePointProjectItemType projectItemType)
    {
        projectItemType.ProjectService.Logger.WriteLine("This message was written " +
            "by using the project service in an extension for the ListDefinition project item.", 
            LogCategory.Message);
    }
}

For more information about creating project item extensions, see How to: Create a SharePoint project item extension.

To retrieve the service in a project item type definition

In your implementation of the ISharePointProjectItemTypeProvider interface, locate the InitializeType method.

Use the ProjectService property of the typeDefinition parameter to retrieve the service.

The following code example demonstrates how to use the project service to write a message to the Output window and Error List window in a simple project item type definition.

<Export(GetType(ISharePointProjectItemTypeProvider))> _
<SharePointProjectItemType("Contoso.CustomAction")> _
Friend Class CustomActionProvider
    Implements ISharePointProjectItemTypeProvider

    Private Sub InitializeType(ByVal projectItemTypeDefinition As ISharePointProjectItemTypeDefinition) _
        Implements ISharePointProjectItemTypeProvider.InitializeType
        projectItemTypeDefinition.ProjectService.Logger.WriteLine("This message was written " & _
            "by using the project service in the Custom Action project item type.", _
            LogCategory.Message)
    End Sub
End Class

[Export(typeof(ISharePointProjectItemTypeProvider))]
[SharePointProjectItemType("Contoso.CustomAction")]
internal class CustomActionProvider : ISharePointProjectItemTypeProvider
{
    public void InitializeType(ISharePointProjectItemTypeDefinition projectItemTypeDefinition)
    {
        projectItemTypeDefinition.ProjectService.Logger.WriteLine("This message was written " +
            "by using the project service in the Custom Action project item type definition.",
            LogCategory.Message);
    }
}

For more information about defining project item types, see How to: Define a SharePoint project item type.

Retrieve the service in Server Explorer extensions

In an extension of the SharePoint Connections node in Server Explorer, you can access the project service by using the ServiceProvider property of an IExplorerNode object.

To retrieve the service in a Server Explorer extension

Get an IServiceProvider object from the ServiceProvider property of an IExplorerNode object in your extension.

Use the GetService method to request an ISharePointProjectService object.

The following code example demonstrates how to use the project service to write a message to the Output window and Error List window from a shortcut menu that the extension adds to list nodes in Server Explorer.

<Export(GetType(IExplorerNodeTypeExtension))> _
<ExplorerNodeType(ExtensionNodeTypes.ListNode)> _
Friend Class ListNodeExtension
    Implements IExplorerNodeTypeExtension

    Private projectService As ISharePointProjectService

    Private Sub Initialize(ByVal nodeType As IExplorerNodeType) _
        Implements IExplorerNodeTypeExtension.Initialize
        AddHandler nodeType.NodeMenuItemsRequested, AddressOf nodeType_NodeMenuItemsRequested
    End Sub

    Private Sub nodeType_NodeMenuItemsRequested(ByVal Sender As Object, ByVal e As ExplorerNodeMenuItemsRequestedEventArgs)
        Dim writeMessageMenuItem As IMenuItem = e.MenuItems.Add("Write Message to Output Window and Error List Window")
        AddHandler writeMessageMenuItem.Click, AddressOf writeMessageMenuItem_Click
    End Sub

    Private Sub writeMessageMenuItem_Click(ByVal Sender As Object, ByVal e As MenuItemEventArgs)
        Dim node As IExplorerNode = CType(e.Owner, IExplorerNode)
        If projectService Is Nothing Then
            projectService = CType(node.ServiceProvider.GetService(GetType(ISharePointProjectService)), ISharePointProjectService)
        End If
        projectService.Logger.WriteLine("Clicked the menu item for " + node.Text, LogCategory.Message)
    End Sub
End Class

[Export(typeof(IExplorerNodeTypeExtension))]
[ExplorerNodeType(ExtensionNodeTypes.ListNode)]
internal class ListNodeExtension : IExplorerNodeTypeExtension
{
    private ISharePointProjectService projectService;

    public void Initialize(IExplorerNodeType nodeType)
    {
        nodeType.NodeMenuItemsRequested += nodeType_NodeMenuItemsRequested;
    }

    void nodeType_NodeMenuItemsRequested(object sender, ExplorerNodeMenuItemsRequestedEventArgs e)
    {
        IMenuItem writeMessageMenuItem = e.MenuItems.Add("Write Message to Output Window and Error List Window");
        writeMessageMenuItem.Click += writeMessageMenuItem_Click;
    }

    void writeMessageMenuItem_Click(object sender, MenuItemEventArgs e)
    {
        IExplorerNode node = (IExplorerNode)e.Owner;
        if (projectService == null)
        {
            projectService = (ISharePointProjectService)node.ServiceProvider.GetService(typeof(ISharePointProjectService));
        }

        projectService.Logger.WriteLine("Clicked the menu item for " + node.Text, LogCategory.Message);
    }
}

Retrieve the Service in other Visual Studio extensions

You can retrieve the project service in a VSPackage, or in any Visual Studio extension that has access to a DTE2 object in the automation object model, such as a project template wizard that implements the IWizard interface.

In a VSPackage, you can request an ISharePointProjectService object by using one of the following methods:

The GetService method of a managed VSPackage that derives from the Package class. For more information, see How to: Get a Service.
The static GetGlobalService method. For more information, see Use GetGlobalService.

In a Visual Studio extension that has access to a DTE2 object, you can request an ISharePointProjectService object by using the GetService method of a ServiceProvider object. For more information, see Getting a service from the DTE object.
