The Solution4 object is a collection of all projects in the current instance of the IDE and all solution-wide properties, such as build configurations. The Solution4 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 Solution4.Item(EnvDTE.Constants.vsProjectKindMisc) or Solution4.Item(EnvDTE.Constants.vsProjectKindSolutionItems).

    _applicationObject = (DTE2)application;
    _addInInstance = (AddIn)addInInst;
    // Pass the applicationObject member variable to the code example.

public void Solution4Example(DTE2 dte)
    // This function creates a solution and adds a Visual C# Console
    // project to it.
        Solution4 soln = (Solution4)_applicationObject.Solution;

        // above.
