SYMPTOMS

You cannot add a smart device application that you create to an existing solution. If the smart device application is not added to the source code control, and then you try to add the smart device application to an existing Windows Application project, you receive the following error message:

Project 'Smart Device Application Name' could not be opened because the Microsoft Visual Basic .NET compiler could not be created. All projects in a Visual Basic solution must target the same platform, but the project you are trying to add targets a platform other than the one specified by your solution.
Note In this error message, Smart Device Application Name is a placeholder for the name of the Smart Device Application solution.

When you try to add the Smart Device Application project from the source code control to an existing Windows Application project, you receive the following error message:

The operation could not be completed.

CAUSE

When you try to add the Smart Device Application project from the source code control to your Windows Application project, the Visual Basic .NET environment tries to open the Windows Application project that is added to the source code control. Visual Basic .NET cannot create an instance of a second compiler. Therefore, Visual Basic .NET sets the IErrorInfo interface, returns an HRESULT failure, and then quits the operation.

STATUS

This behavior is by design.
