One or more errors occurred while processing template 'Entity.tt'.

It's been three years and this tool has not been updated?

Should be updated for VS 2015.

Great !! Vinicius Nunes Macedo
no-one think about this !!

The solution is simple.
#Full Mode
Make the download of project and change framework to 4.5 and rebuild
#Easy Mode
I rebuild in 4.6 and change for VS2015 too.

Is anyone else having an issue with this after installing Update 2 for VS2015? I installed it yesterday and now every time I try to execute the reverse engineer function I get the following error:

One or more errors occurred while processing template 'Entity.tt'.
error : An exception was thrown while trying to compile the transformation code. The following Exception was thrown:
System.ArgumentException: Empty path name is not legal.

EDIT: It is still working fine in VS2013.

Needs to be updated to VS2015. I know how to hack it to work, but it's been long enough they should have this updated.

Direct download to VS 2015 fixed version: http://1drv.ms/1RWxOsb

Thank you 林选臣 for the fix!!! It works well on VS2015.

by Bsambrone | January 30 2016

Works great, but I really would like this for VS2015 so I don't have to keep bouncing back and forth.

by Brett Dille | January 27 2016

Is there any way to run the Reverse Engineer Code First from the Command Line? I'd like to automate a rebuild whenever the data model changes using some custom templates. Thanks!

by SamStrong | January 22 2016

Please create a VS2015 version.
