    <p>I've been on a tear lately trying to learn everything I can about .Net Multithreading. (Getting better at it, but still feel like there's lots to learn). Right now I'm focusing on the APM (Asynchronous Programming Model) which is commonly known as this:</p> <pre><code>//non async method public int DoSomeWork(int arg) { //do something and return result } //async version public IAsyncResult BeginDoSomeWork(int arg, AsyncCallback callback, object @object) { } public int EndDoSomeWork(IAsyncResult result) { } </code></pre> <p>Now, let's say I'm writing some library, and I want to expose this functionality to anyone who's consuming my API, I was thinking about ways to implement this pattern. Implementing the IAsyncResult interface is a possibility, but it seems quite complex. My question is, if using delegate is an acceptable solution. What I mean by that is this:</p> <pre><code>public class MyClass { private Func&lt;int, int&gt; func; //non async method public int DoSomeWork(int arg) { //do something and return result } //async version public IAsyncResult BeginDoSomeWork(int arg, AsyncCallback callback, object @object) { this.func = new Func&lt;int, int&gt;(DoSomeWork); var asyncResult = this.func.BeginInvoke(arg,callback,object); return asyncResult; } public int EndDoSomeWork(IAsyncResult result) { return this.func.EndInvoke(result); } } </code></pre> <p>Basically, every delegate has the BeginXxx and EndXxx functionality baked right into it. Is it OK to take advantage of that and just expose the IAsyncResult, or is there something wrong with this that I'm not thinking of. </p>

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.
