    <p>I'm using VisualStudio Ultimate 2012 (Update 1) on Windows 7. I can get my T4 template to generate a file by: <em>right click [tt file] | run Custom tool</em>. That works great! (yay for me). It also works if I run the menu command: <em>Build | Transform All T4 Templates</em>. But I want automation! I run into a problem when I try to get the generated code file to be produced with every build -- which is my goal.<br> I looked at this: <a href="https://stackoverflow.com/questions/1293320/t4-transformation-and-build-order-in-visual-studio">T4 transformation and build order in Visual Studio</a></p> <p>this isn't what I want. It discusses using a pre-build build event. I wanted it to be part of the build.</p> <p>and this: <a href="https://stackoverflow.com/questions/3427079/is-there-a-way-to-get-visual-studio-to-run-transform-all-templates-upon-a-succ">Is there a way to get Visual Studio to run “Transform All Templates” upon a successful build?</a></p> <p>this isn't what I wanted either. It discusses using a post-build event.</p> <p>then I found this: <a href="http://www.olegsych.com/2010/04/understanding-t4-msbuild-integration/" rel="nofollow noreferrer">Understanding T4: MSBuild Integration</a></p> <p>from <a href="http://www.olegsych.com/" rel="nofollow noreferrer">Oleg Sych's blog</a>:</p> <p>Perfect! This is what I want. Although his blog discusses VS2010, I have adopted it to VS2012 where applicable.</p> <p>I walked through each of his steps for implementing this. I installed <a href="http://www.microsoft.com/en-us/download/details.aspx?id=30668" rel="nofollow noreferrer">Visual Studio SDK 2012</a> &amp; <a href="http://www.microsoft.com/en-us/download/details.aspx?id=30680" rel="nofollow noreferrer">Visual Studio Visualization and Modeling SDK (2012)</a></p> <p>I started with using the Tangible T4 plug in, but thinking there was a problem with that, I used Oleg's T4 Toolbox Beta. Sadly, with either I seemed to get the same results: an error with a build.</p> <p>I followed his instruction on his site and reread all the steps and parts. I have been researching for days, and now my first post here. I am stuck. Thanks for looking...</p> <p>To recap: I get an error when I build in visual studio 2012 or when I run the msbuild from the command-line (but again not when I <em>run Custom Tool</em> or use the manual <em>Transform All T4 Templates</em> - Both of those work fine).</p> <p>Here is my t4template called <code>s_code.tt</code>:</p> <pre><code>&lt;#@ template debug="true" hostSpecific="true" language="C#" #&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
