wenchiwang WSE 3.0 and ArrayList problems
I have a WSE 2.0 SP3 server app with one method that receives a class that contains an ArrayList as a property. Last week I decided to migrate my app to WSE 3.0. Now I got an InvalidCastException. When I debugged the app I found that the ArrayList contains in each element an array with two elements: the first one of XmlText type with the value and the second one of XmlAttribute with the original element type.

Nehal Sheth VS 2005 Slow
I was comparing 2003 to 2005 for an upcoming project and was surprised at the slow performance of 2005 (Maybe I'm doing something wrong). What I'm doing is loading 5 tables (About 80,000 records total) into a dataset that will be used to validate weekly transactions. It takes 80 seconds to load all of the tables in 2005 and only 10 seconds in 2003. I'm using the same code for both version. Is there a better way to do this in 2005 or a way to opt ...Show All
