By default for new projects, the targeted framework is set to .NET Framework 4. The IDE does not support modifying the targeted framework, but you can change it manually.
In the project file (.vcxproj), the default targeted framework is represented by the <TargetFrameworkVersion>v4.0</TargetFrameworkVersion> property element. To change the targeted framework, unload the project, use a text editor to open the project file, and then change the value of the property element from v4.0 to another version that is installed on your server. For example, if you specify v3.5, which represents the .NET Framework 3.5, Visual Studio 2008 SP1 must be installed. Save and close the file, reload the project, and verify that the targeted framework is displayed in the property page. For more information, see How to: Modify the Target Framework and Platform Toolset.
ActiveX reference properties are available only for references to COM components. These properties are displayed only when a COM component is selected in the References pane. The properties cannot be modified.
Control Full Path
Displays the directory path of the referenced control.
Displays the GUID for the ActiveX control.
Displays the version of the referenced ActiveX control.
Type Library Name
Displays the name of the referenced type library.
Displays the tool that is used to build the interop assembly from the referenced COM library or ActiveX control.
Assembly reference properties are available only for references to .NET Framework assemblies. These properties are displayed only when a .NET Framework assembly is selected in the References pane. The properties cannot be modified.
Displays the relative path from the project directory to the referenced assembly.
The following properties define a project-to-project reference from the project that is selected in the References pane to another project, which typically is not in the same solution. The selected project is the dependent project and the other project is the independent project. As the result of creating a project-to-project reference, the independent project is built before the dependent project. A project reference applies to a specific dependent project, not the entire solution. For more information, see Managing Project References.
Link Library Dependencies
When this property is True, the project system links into the dependent project the .lib files that are produced by the independent project. Typically, you will specify True.
Uniquely identifies the independent project. The property value is an internal system GUID that cannot be modified.
Use Library Dependency Inputs
When this property is False, the project system will not link into the dependent project the .obj files for the library produced by the independent project. Consequently, this value disables incremental linking. Typically, you will specify False because building the application can take a long time if there are many independent projects.
