<p>I'm investigating the differences between using log4net and <code>System.Diagnostics.Trace</code> for logging, and I'm curious about the performance differences I've observed.</p>
<p>I created a test application to compare the performance of both logging methods in several scenarios, and I'm finding that log4net is... | <p>yes log4xxx is slower than trace, since trace is normally a near kernel tool, while log4xxx is a much more powerful tool. Personally I prefer log4xxx because of it's fexibility, but if you want something that doesn't impact as much, and you don't really need logs for production,say in debug only trace should be enou... | <p>Have just run a test comparing sequental writing to a simple file compared to using Log4Net for the same task.Log4Net is about 400 times slower comparet to a StreamWriter.So <strong>I consider Log4Net not usable if You are writing to huge logfiles</strong>.

<p>I am using ASP.NET ajax to dynamically add/remove controls from a page without using full postbacks. The UI is very complicated. Under certain scenarios, when a control on the page causes a full postback, after changing the controls via async postbacks, I get this error:</p>
<p><a href="https://stackoverflow.com/... | <p>If you have a WYSIWYG input text box or a textbox expecting HTML, then you have to disable validation or do some JavaScript hack.</p>
<p>The catch is that you will need to provide thorough validation to prevent XSS and such.</p>

<p>However, if your UI is very complicated, there's probably something wrong with it. Following KISS is a good idea for obvious reasons.</p>

<p>Its my understanding that the recommended approach to localization in WPF is to use the LocBaml tool to extract the localizable items into e.g. a csv file, translate the items into the desired language and regenerate a new sattelite assembly from this csv file. However from my experiments this seems to conflict with... | <p>You have to manually do this generating .resources from LocBaml and then merging the Resx and BAML resources using the Assembly linker. </p>
<p>The process looks something like this:</p>

<p>I am currently creating a master ddl for our database. Historically we have used backup/restore to version our database, and not maintained any ddl scripts. The schema is quite large.</p>

<p>The nice thing about building all the tables first and then building all the constraints, is that the tables can be created in any order.
