on installation from within a brand new MVC3 C# project, I get the following errors:

Thanks for reporting this. I will have to try this when I get some
free time in this week. Can you try the same thing on a fresh project?
In the past I have seen people having such issues when a previously
installed Nuget package was removed but the dependencies were still

hanging around in the project.

[rwhitmire]

yes, this occurs on a fresh project, both MVC3 and Empty Web Application.

[comfreakph]

try to Install separately the T4Scaffolding

[drgrieve]

I had the same issue. As comfreakph mentions you MUST install T4scaffolding first. (and possibly restart VS) before installing MvcMailer.

[rwhitmire]

OK thanks! I'm writing an app that need some email stuff now so I'll try it out in the next day or two.

[krokonoster]

Just to confirm, after struggling the better part of an hour to get this working:
I had the same issues, so installed T4scaffolding, restart VS and then installed MvcMailer.
Ran T4scaffolding "Scaffold Mailer UserMailer Welcome,GoodBye" and FINALLY it's working.
Too nice a tool this to give up on, but seriously try and sort out this issues. :-)

[ericjohannsen]

Same issue here. Hopefully it can be resolved soon. Great package, hate to lose people that can't get past this problem.

[ctolkien]
