Solution Interface

Represents all projects and solution-wide properties in the integrated development environment (IDE). Use this object for functionality and refer to _Solution for documentation.

Namespace: EnvDTE
Assembly: EnvDTE (in envdte.dll)

[GuidAttribute(L"26F6CC4B-7A48-4E4D-8AF5-9E960232E05F")] 
public interface class Solution : _Solution
/** @attribute GuidAttribute("26F6CC4B-7A48-4E4D-8AF5-9E960232E05F") */ 
public interface Solution extends _Solution
GuidAttribute("26F6CC4B-7A48-4E4D-8AF5-9E960232E05F") 
public interface Solution extends _Solution

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

Reference this object by using DTE.Solution. To refer to virtual projects, such as MiscFiles or SolutionItems, use Solution.Item(EnvDTE.Constants.vsProjectKindMisc) or Solution.Item(EnvDTE.Constants.vsProjectKindSolutionItems).

This example works only in Visual Studio .NET 2003. For more information, see Migrating Code that Creates Projects by Using Templates.

Sub SolutionExample()
   ' This function creates a solution and adds a Visual Basic Console
   ' project to it. 
   Dim soln As Solution
   Dim proj As Project
   Dim msg As String

   ' Create a reference to the solution.
   soln = DTE.Solution

   ' Create a new solution.
   soln.Create("c:\temp2", "MyNewSolution")

   ' Create a new Visual Basic Console application project.
   ' Adjust the save path as needed.
   proj = soln.AddFromTemplate("D:\Program Files\Microsoft Visual Studio .NET\Vb7\VBWizards\ConsoleApplication\Templates\1033\ConsoleApplication.vbproj", "c:\temp2", "My New Project", True)
   ' Save the new solution and project.
   soln.SaveAs("c:\temp2\newsolution.sln")
   msg = "Created new solution: " & soln.FullName & vbCrLf
   msg = msg & "Created new project: " & proj.Name
   MsgBox(msg)
End Sub
