POCould not load file or assembly App_Web_ * with a precompiled ASP.NET website project
text
Body
copied!<p>I'm getting this problem on a very specific page and I'm not sure how to fix it. I've already found several SO questions (such as <a href="https://stackoverflow.com/questions/784157/asp-net-corrupt-assembly-could-not-load-file-or-assembly-app-web">ASP.NET corrupt assembly "Could not load file or assembly App_Web_*"</a> and <a href="https://stackoverflow.com/questions/5538454/could-not-load-file-or-assembly-app-web-xxxxxxxx-or-one-of-its-dependencies">Could not load file or assembly App_Web_xxxxxxxx or one of its dependencies</a>) and tried their solutions, but to no avail.</p> <p>To recap, here's what I've tried:</p> <ul> <li><p>Set <code>batch="false" numRecompilesBeforeAppRestart="50"</code> in the web.config</p></li> <li><p>Restarted the IIS website that hosts this website</p></li> <li><p>Cleared the ASP.NET temporary files in <code>%windir%\Framework64\v4.0.30319\Temporary ASP.NET Files</code></p></li> <li><p>Reployed</p></li> </ul> <p>... and any combination of the above, but to no avail. It works perfectly fine when I attempt to run the site from VS and when I deploy the website without pre-compilation. </p> <p>Here are some specs of the enviroment:</p> <ul> <li><p>Pre-compilation is done through a Web Deployment Project. It does not matter if TFS or I did the precompilation: the problem persists</p></li> <li><p>.NET version is 4.0.30319</p></li> <li><p>AppPool settings: Pipeline mode is Integrated on .NET 4.0</p></li> </ul> <p>This is the specific error, which occurs when I open <code>Customer.aspx</code>:</p> <p><code>Could not load file or assembly 'App_Web_qxcfa0wv, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.</code></p> <p>This page has registered a control called <code>UserManagement.ascx</code>, located at <code>~/Controls/UserManagement.ascx</code>. </p> <p>That control has registered another control called <code>UserDialog.ascx</code>, which is located at <code>~/Controls/Dialogs/UserControl.ascx</code>.</p> <p>And that last control uses a control called <code>~/Controls/User.ascx</code> which encapsulates the data of a user. There are no further dependencies.</p> <p>According to the stack trace, the error is on line 1 of <code>UserDialog.ascx</code> (The <code><%@ Control ... %></code> directive).</p> <p>I'm at a loss. My <em>guess</em> is that it doesn't work because <code>~/Controls/Dialogs/UserDialog.ascx</code> requires a control which is in a parent folder, which results in some out of date reference during runtime. Kind of like the problem description in the first SO question. </p> <p>However, I can't test that simply by excluding the <code>~/Controls/User.ascx</code> control because then I'm getting circular reference errors in another control which is used in <code>~/Control/UserDialog.ascx</code>, even though that control doesn't register any other controls, either. Only a namespace registration, which <em>is</em> used by most other controls. </p> <p>I'd say that the circular reference and the error are related, though, but I can't quite say how. Not without drawing an entire dependency graph.</p> <p>Any ideas?</p> <p>Thanks in advance!</p>
