POApp.Config Ignored After Pre-Build Event
text
Body
copied!<p>I have a solution with several projects and several developers, each with their own environment (of course). To manage connection strings between each environment, I have created several app.config files for each environment: app.config.dev, app.config.qa, etc.</p> <p>The pre-build event simply copies the app.config.$(ConfigurationName) to app.config. This pre-build event is done for each project in the solution, and the connection string is included in each (including the test project).</p> <p>When I use the pre-build events to manage the app.config files, the connection string cannot be found. I can get the tests to run fine by 2 methods: 1. Do not use the pre-build events to manage the app.config file selection, and do it myself or 2. If I check out app.config and make it writable, then the pre-build events work just fine.</p> <p>We are using Visual Studio 2008 with VSS.</p> <p>I'm down to my last grey hair here, any ideas? Thanks in advance!</p> <p><strong>SOLUTION</strong> Update the pre-build event to ensure the app.config file is writable even if it is checked in. Pre-Build event used below:<br> <code>@echo off</code> </p> <p><code>attrib -r $(ProjectDir)app.config</code><br> <code>if errorlevel 1 goto AttribFailed</code> </p> <p><code>copy $(ProjectDir)app.config.$(ConfigurationName) $(ProjectDir)app.config</code><br> <code>goto BuildOK</code></p> <p><code>:AttribFailed</code><br> <code>echo Attrib -r Failed on $(ProjectDir)app.config</code><br> <code>exit 1</code></p> <p><code>:BuildOK</code><br> <code>echo Copy Done</code></p>
