- After you install the Design-Time Update for Visual Studio 2010 SP1, Visual Studio 2010 will automatically select Platform Update 1 as the target framework for any new projects. To develop applications for any other .NET Framework version, you must select the appropriate .NET Framework version in the Target Framework list.
- If the target framework is not set as Platform Update 1 correctly, you cannot build against any applications that call new public APIs from Runtime Update for Platform Update 1.
- If you change the target framework to any other.NET Framework version instead of Platform Update 1, the State Machine toolbox is not displayed. Therefore, inconsistencies occur in the active workflow project that uses Platform Update 1.
