A VSIP package built using VS2005 SDK and VS2010 compiler, returns pUpgradeRequired as true when UpgradeProject_CheckOnly method is invoked for a solution file, including a website and a C# project in respective order. This occurs in both Visual Studio 2010
SP1 and Visual Studio 2012. The issue is not seen when we reverse the order i.e, modify the solution file to include the C# project before website or when we build the VSIP package with VS 2005 SDK and VS2005 compilers. The issue is not visible if the website
project is not included in the solution file.
Would appreciate if someone can confirm as to whyUpgradeProject_CheckOnly behavior changes with a website project inclusion in the solution file ?
Thanks,
