Collaborative development of Office solutions
Multiple developers can work on an Office project in the same way that they collaborate on other Visual Studio projects. Visual Studio correctly locates the Microsoft Office installation on each computer, even if Office is installed in different locations. However, there are some important considerations to be aware of.
Applies to: The information in this topic applies to document-level projects and VSTO Add-in projects. See Features available by Office application and project type.
Debug properties are not shared
Debug properties are not shared among multiple users under source control. Visual Basic and Visual C# projects store the debugging properties in a user-specific file (ProjectName.vbproj.user or ProjectName.csproj.user), and this file is not under source control. If more than one person is debugging, each person must enter debug properties manually.
If the project is housed on a network share instead of in source control, some extra steps must be taken to enable the collaborating developers to open the solution and test the assembly.
Source control requires checking out all files
If you use source control for your projects, you should check out all of the files under a code file in Solution Explorer (such as the ThisDocument, ThisWorkbook, or ThisAddIn code files) every time you change the code file, even the files that are hidden by default. If you check out only the top-level code file, your changes might be lost.
After you make your changes, check all of the files back in. For more information about hidden code files in projects, see Office projects in the Visual Studio environment.
Security for informal collaboration on a network
For all document-level solutions that are in a network location (such as \\Servername\Sharename), the fully qualified location must be added to the trusted folder list in the Microsoft Office application that you are working with. Select the option to include the subdirectories under the main folder, or specifically add debug and build folders to the trusted folder list. For more information about how to do this, see Grant trust to documents.
The temporary certificates that are automatically generated at build time are not secured by passwords. The certificates contain the developer's login name and other personal information. If you deploy customizations that are signed by temporary certificates, others might be able to access this information.
