    <p><strong>Assembly.GetEntryAssembly()</strong> does not work for web applications.</p> <p>But... I really need something like that. I work with some deeply-nested code that is used in both web and non-web applications.</p> <p>My current solution is to browse the StackTrace to find the first called assembly.</p> <pre><code>/// &lt;summary&gt; /// Version of 'GetEntryAssembly' that works with web applications /// &lt;/summary&gt; /// &lt;returns&gt;The entry assembly, or the first called assembly in a web application&lt;/returns&gt; public static Assembly GetEntyAssembly() { // get the entry assembly var result = Assembly.GetEntryAssembly(); // if none (ex: web application) if (result == null) { // current method MethodBase methodCurrent = null; // number of frames to skip int framestoSkip = 1; // loop until we cannot got further in the stacktrace do { // get the stack frame, skipping the given number of frames StackFrame stackFrame = new StackFrame(framestoSkip); // get the method methodCurrent = stackFrame.GetMethod(); // if found if ((methodCurrent != null) // and if that method is not excluded from the stack trace &amp;&amp; (methodCurrent.GetAttribute&lt;ExcludeFromStackTraceAttribute&gt;(false) == null)) { // get its type var typeCurrent = methodCurrent.DeclaringType; // if valid if (typeCurrent != typeof (RuntimeMethodHandle)) { // get its assembly var assembly = typeCurrent.Assembly; // if valid if (!assembly.GlobalAssemblyCache &amp;&amp; !assembly.IsDynamic &amp;&amp; (assembly.GetAttribute&lt;System.CodeDom.Compiler.GeneratedCodeAttribute&gt;() == null)) { // then we found a valid assembly, get it as a candidate result = assembly; } } } // increase number of frames to skip framestoSkip++; } // while we have a working method while (methodCurrent != null); } return result; } </code></pre> <p>To ensure the assembly is what we want, we have 3 conditions :</p> <ul> <li>the assembly is not in the GAC</li> <li>the assembly is no dynamic</li> <li>the assembly is not generated (to avoid temporary asp.net files</li> </ul> <p>The last problem I meet is when the base page is defined in a separate assembly. (I use ASP.Net MVC, but it'll be the same with ASP.Net). In that particular case, it's that separate assembly that is returned, not the one containing the page.</p> <p>What I am looking for now is :</p> <p>1) Are my assembly validation conditions enough ? (I may have forgotten cases)</p> <p>2) Is there a way, from a given code-generated assembly in the ASP.Net temporary folder, to get information about the project that contains that Page / View ? (I think not, but who knows...)</p>

    1. CO"Entry assembly" doesn't really have any meaning in an ASP.NET application, as many ASP.NET applications are a ton of assemblies working in tandem executing code at the appropriate times. What are you actually trying to do?

    2. COI totally agree with you, a web application as no "entry assembly". In fact, we can consider they are have multiple entry points. What I ultimately need is to get what's in the AssemblyInfo.cs file, in the entry assembly. Why I want to do that is not the point here.

    3. COI need to do a similar task, and couldn't find a better way than this, generally. Is `ExcludeFromStackTraceAttribute` a class of yours? I can't seem to find it in the BCL. Same question with `GetAttribute<>`, is that a method you made for convenience?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
