I can see this by seeing that the constructor gets called each time I call a method. I only instantiate the proxy web service once in the client. This would mean I wou...
The .NET framework is massive. I've used it for years and I've still not used most of it. I'd like to expand my knowledge of the Framework's backwaters but just reading thought it seems daunting. So I thought I'd tap up the Stack Overflow community first. What part have you found to be the most surprisingly useful? What's your favouri...
I'm adding an About dialog to my .NET application and I'm querying the assembly's attributes for information to display.

In chapter eight (p189) of "CLR Via C#", Jeffrey Richter states that: "A Type constructor can be applied to interfaces (although C# doesn't allow this)" I've done a little bit of research and I can't seem to find why an interface would ever need a type constructor, in any language. This seems like something that you would explicitly di...
I need to produce multiple HTML report files from an XML data file and I'm using C# (.NET 3.5). I essentially need on HTML report for each of certain child trees in the XML file (but they have to include some parent info). I've decided to use XSLT, because it seems to be the most elegant solution to my problem. I can then use the .NET X...

When you create a Windwows Service, you end up with a .exe file that you need to register, and you start it from the "Services" snap-in. If you try to execute this .exe file, you get the message: "Cannot start service from the command line or debugger. A Windows Service must first be installed (using installutil.exe) and then started wi...
I was playing around with DynamicMethod and Expression Trees' Compilation (which uses DynamicMethod internally). I then wondered if there is a way to add a custom attribute to the generated method. I googled about it, but I couldn't find a way. I know that it's possible to do using CodeDom, but I want to use DynamicMethod. Someone ment...

I like them, but want to write my own wrapper without using an added dependency. All wrappers I find that don't require an added dependency aren't free. I'm wondering how one would rea...
If I have a nested loop scenario and I am stepping into it in debug mode. Ex: for (int i = 0; i < listTest.Count; i++) { for (int j = 0; j < anotherList.Count; j++) { //Some logic that throws an exception } } Is there a way for me to know the values of i, j, listTest[i] and anotherLIst[j] just before the exception occur...
