Error in Nuget PM Visual Studio Express v2013

I could not resolve this error from Nuget Package Manager.

I tried disabling T4 Scaffolding and reinstalling. I developed this program in Visual Studio 2012 with three updates and now ported the program to VS Express 2013. There were no errors in the 2012 version. I searched the Internet, Nuget and this site, and I could not solve it. I should mention that I have MvcMailer in packages, and it seems to rely on T4 Scaffolding. And the answers will be appreciated.

Unfortunately, Microsoft made a huge mistake in VS2013. They replace the "old" way of scaffolding with what is called an artery ... I use T4 scaffolding in all my nuget packages, and now none of them can be used in VS2013 :(

I asked several MS staff about this, including the T4scaffolding developers, without getting a satisfactory answer.

It’s good that they are working on this “artery”, but they made a big mistake by losing the support of Env.DTE :(

The only solution right now is to use VS2012 until this error is fixed :(
