ASP.NET

Hi,

For a web application developed on ASP.NET, we are finding that for user control files (ascx) we are returning long strings as a result of method calls. These are embedded in the ascx pages using the special tags <% %>

When performing memory dump analysis for the application, we find that many of those strings are not being garbage collected. Also, the ascx pages are compiled to temporary DLLs and they are held in memory. Is this responsible for causing the long strings to remain in memory and not be garbage collected ?

Note : The strings are larger than 85K in size.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
