Now that ASP.NET MVC 2 is out, I tried to install it on my development machine, which already has Visual Studio 2010 RC installed and I got this error message during installation
Component Microsoft ASP.NET MVC 2 has failed to install with the following error message:
“A different version of ASP.NET MVC 2 is already installed on your system. Please uninstall this version before proceeding with this install.”
Sure enough, the MVC 2 release notes state:
Note Because Visual Studio 2008 and Visual Studio 2010 RC share a component of ASP.NET MVC 2, installing the ASP.NET MVC 2 RTM release on a computer where Visual Studio 2010 RC is also installed is not supported.
So my question is, though officially unsupported, if I uninstall VS 2010 RC, install MVC 2 then re-install VS 2010 RC, might this work? And would I then be able to target MVC 2 in VS2010?
See http://haacked.com/archive/2010/02/10/installing-asp-net-mvc-2-rc-2-on-visual-studio.aspx. This is unsupported, but the same general steps should work.
