Hello,
I have searched around the internet for a solution to my problem but I have yet to solve it after several hours of debugging.
I have a project that was developed a while back using Visual Studio 2010, Visual FoxPro 9.0, Westwind, and Entity Framework. We then got Visual Studio 2013 which is where the project has been edited ever since and everything is working just fine.
We would like to bring the project up to speed with newer technology. But I am getting an error just by opening the project within a newer version of Visual Studio. But the error is probably due to it being loaded on a different machine I am thinking.
Can anyone help me out?
