<p>How can I take full advantage of 64-bit architecture in my .NET 2.0 Web Applications and Console/Forms Applications?</p>
| <p>I think there is not too much you can optimize in your managed .NET code regarding 32bit vs. 64bit architectures. This is because most of the differences and optimizatinons are most likely already implemented by the underlying VM. As mentioned in <a href="https://stackoverflow.com/questions/280327/programming-for-th... | <p>The best gain of 64 bit platform is an amount of memory yours application can address. This means what you web application can support a larger amount of active sessions or/and longer sessions. Also you can store more data in the application cache. So keeping this in mind you can re architect you app.</p>

<p>We primarily use an ASP.NET environment at work. Right now I'm building an application which uses "Modules", which is just a UserControl, with its' Javascript right in the control, and a link element to the stylesheet for that control. I want to keep it modular, and would like the style of this control to be indepen... | <p>It sounds like you're rolling your own theme engine... why not use ASP.NET Themes?</p>
<p>If you're determined to do it yourself, here's some code from the <a href="http://www.codeplex.com/cssfriendly" rel="nofollow noreferrer">CssFriendly project</a> that may be of interest to you.

<p>If you're using a .skin file, or if the majority of the app is also plugged into the theme, you might as well go with the theme. </p>

<p>I was looking for something like Server.MapPath in the ASP.NET realm to convert the output of Assembly.GetExecutingAssembly().CodeBase into a file path with drive letter.</p>

<p>This line in YUI's <a href="http://developer.yahoo.com/yui/reset/" rel="nofollow noreferrer">Reset CSS</a> is causing trouble for me:</p>

<pre><code>strong, b, strong *, b * { font-weight: bold; }

}
em, i
{
font-style: italic;
font-weight: inherit;
}
</code></pre>
<p>Unfortunately, Internet Explorer doesn't support "inherit." :-(</p>

<p>I am walking through the MS Press Windows Workflow Step-by-Step book and in chapter 8 it mentions a tool with the filename "wca.exe". This is supposed to be able to generate workflow communication helper classes based on an interface you provide it. I can't find that file. I thought it would be in the latest .NET... |

<p>Do you do automated testing on a complex workflow system like K2?</p>
<p>We are building a system with extensive integration between Sharepoint 2007 and K2. I can't even imagine where to start with automated testing as the workflow involves multiple users interacting with Sharepoint, K2 workflows and custom web pag... | <p>I'm having a similar problem testing workflow-heavy MOSS-based application.
