The Solution2 type exposes the following members.


  Name Description
Public property AddIns Gets an AddIns collection, which contains all currently available Add-ins associated with the solution.
Public property Count Gets a value indicating the number of projects in the solution.
Public property DTE Gets the top-level extensibility object.
Public property Extender Gets the requested Extender object if it is available for this object.
Public property ExtenderCATID Gets the Extender category ID (CATID) for the object.
Public property ExtenderNames Gets a list of available Extenders for the object.
Public property FileName Infrastructure. Microsoft Internal Use Only.
Public property FullName Gets the full path and name of the object's file.
Public property Globals Gets the Globals object that contains any variable values that may be saved in the solution (.sln) file, the project file, or the user's profile data.
Public property IsDirty Infrastructure. Microsoft Internal Use Only.
Public property IsOpen Gets a value which indicates whether a solution is open.
Public property Parent Gets the immediate parent object of a Solution2 object.
Public property Projects Gets a collection of the projects currently in the solution.
Public property Properties Gets a collection of all properties that pertain to the Solution2 object.
Public property Saved Gets or sets a value indicating whether a solution has not been modified since last being saved or opened.
Public property SolutionBuild Gets the SolutionBuild object for the solution, which represents the root of the build automation model at the solution level.
Public property TemplatePath Superseded by GetProjectTemplate.



  Name Description
Public method AddFromFile Adds a project to the solution that is based on a project file already stored in the system.
Public method AddFromTemplate Copies an existing project file, and any items or subdirectories it contains, to the specified location and adds it to the solution.
Public method AddSolutionFolder Adds a solution folder to a ProjectItems collection.
Public method Close Closes the current solution.
Public method Create Creates an empty solution in the specified directory with the specified name.
Public method FindProjectItem Locates an item in a project.
Public method GetEnumerator Returns an enumeration for items in a collection.
Public method GetProjectItemTemplate Returns a path to the indicated project item template.
Public method GetProjectTemplate Returns a path to the indicated project template.
Public method Item Returns an indexed member of a Projects collection.
Public method Open Opens a specified solution.
Public method ProjectItemsTemplatePath Superseded by GetProjectItemTemplate.
Public method Remove Removes the specified project from the solution.
Public method SaveAs Saves the solution.



This interface contains a collection of all projects in the current instance of the IDE and all solution-wide properties, such as build configurations. It contains a project element for every project, whether it is a wrapped project, a subproject, or a top-level project.

You can find the open solution by using the DTE.Solution property. To refer to virtual projects, such as MiscFiles or SolutionItems, use Solution.Item(EnvDTE.Constants.vsProjectKindMisc or Solution.Item(EnvDTE.Constants.vsProjectKindSolutionItems.

The following code creates a new console application solution in the given path.

Public Sub OnConnection(ByVal application As Object, _
 ByVal connectMode As ext_ConnectMode, ByVal addInInst As Object, _
 ByRef custom As Array) Implements IDTExtensibility2.OnConnection
    _applicationObject = CType(application, DTE2)
    _addInInstance = CType(addInInst, AddIn)
End Sub

Sub SolutionExample(ByVal dte As DTE2)
    ' This function creates a solution and adds a Visual Basic Console
    ' project to it.
        Dim soln As Solution2 = CType(DTE.Solution, Solution2)
        Dim vbTemplatePath As String
        ' This path must exist on your computer.
        ' Replace <file path> below with an actual path.
        Dim vbPrjPath As String = <file path>
        ' Get the project template path for a Visual Basic console application project.
        vbTemplatePath = soln.GetProjectTemplate _
        ("", "VisualBasic")
        ' Create a new Visual Baic Console project using the template obtained 
        ' above.
        soln.AddFromTemplate(vbTemplatePath, vbPrjPath, _
        "New Visual Basic Console Project", False)
    Catch ex As System.Exception

End Sub
//you will need to add this reference to your project as well
using System.Windows.Forms;  

public void OnConnection(object application,
 Extensibility.ext_ConnectMode connectMode, object addInInst,
 ref System.Array custom)
    _applicationObject = (DTE2)application;
    _addInInstance = (AddIn)addInInst;
    // Pass the applicationObject member variable to the code example.

    // project to it.

        // The file path must exist on your computer.
        // Replace <file path> below with an actual path.
        String csPrjPath = <file path>;

        // Create a new C# Console project using the template obtained 
        // above.
