>>You won't likely have the Business layer generator in VS 2015 but the projects should work fine. Last I heard OakLeaf was working on a update for VS 2015. I have several projects that I work within VS 2015 without issues but I also do not use the assemblies from the GAC.


I must have miscommunicated something. I thought that is what I said as well. I actually have several existing and some new projects using MM in VS 2015 with no issues. The only thing missing will be the VS installed add-ins such as Business Layer Generator (BLG) and perhaps if you are using any custom controls such as traditional ASP .NET Forms controls, they won't be installed into the toolbox.
