    <p>Right now we just use something like this</p> <pre><code> stopWatch.Start(); try { method(); } finally { stopWatch.Stop(); } </code></pre> <p>Which works fine for synchronous methods, but some are executing asynchronously, so the time is skewed when multiple threads are executing. Is there an equivalent to System.Diagnostics.Stopwatch that will measure only time spend in the current thread?</p> <p>We want to collect data over an extended period of time in our internal beta(alpha?) release, and running under a profiler full time isn't a feasible option.</p> <p>Edit: To clarify, we want to only measure the time spent executing method(), so if Method1() and Method2() both start at the same time and Method1 finishes at the 2 second mark and Method2 finishes at the 4 second mark, I want something that would tell me that Method1 spent about 1 second executing and Method2 spend about 3 seconds executing (Assuming during the first 2 seconds they shared the (assumed single core) processor equally.</p>

    1. COAre you asking for processor time spent in method() vs overall elapsed time because other threads are using the CPU while method() is executing? Or is method() starting some async stuff and you want to capture that time as part of the elapsed time?

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.
