We are currently evaluating the upgrade from VS 2010 to VS 2012 as we require features from .Net framework 4.5. During this evaluation I just stumbled upon the issue that VS 2012 is unable to locate the envdte.dll from within a T4 template file.

This will fail:
<#@ Assembly Name="envdte.dll" #>
with the error: Compiling transformation: Metadatafile 'envdte.dll' could not be found

To resolve the issue we currently have to specify the full path to the envdte.dll so this will work:
<#@ Assembly Name="C:\Program Files (x86)\Common Files\microsoft shared\MSEnv\PublicAssemblies\envdte.dll" #>

Although a possible workaround is available, it should not be necessary to specify the full path to the dll and should, in my opinion, be considered a bug and treated as such.

Kind regards,

Tobias

envdte.dll can not be found

VS 2012 should behave like VS 2010 in this point and envdte.dll should be found by VS 2012.

Thanks for you feedback. To make this work remove the .dll from envdte. When you specify the extension, T4 thinks you want a fully qualified path. If you change your attribute to <#@ assembly name="envdte" #>, it will work.
