We have a lot of code that passes about “Ids” of data rows; these are mostly ints or guids. I could make this code safer by creating a different struct for the id of each database table. Then the type checker will help to find cases when the wrong ID is passed. E.g the Person table has a column calls PersonId and we have code like: ...
In my application I have been asked to send error codes via SNMP traps. I believe that this will need to be done using version 3 because of the security issues with versions 1 and 2. Is there anything in the .net framework to do this or should I be looking to buy a third party library. ...

I am trying to return an XMLReader from a data access class that calls a stored proc to run a FOR XML query. The problem is, I can't call close() on the sql connection when I return the xmlreader or the reading will terminate.

It may be a subjective question but I want to know what people feel is the best pattern for behavior of an object's save or delete methods? When you setup a class that will contain Db record information I usualy end up declaring the objects Delete() and Save() methods as void. As these methods usualy take direct action on other properti...
I was asked to write a database and it's GUI frontend for some non-profit organization I am member of. The decision was to use .NET as I know C# fariy good and writing GUI is quite easy.

My application has just leaked 1.5GB of memory. I guess since I don't have a ton of data available to me, I'm assuming that it's leaked the memory, but it could also just be holding onto it. I'm currently using perfmon to gather as much information as I can, to try to understand what could be causing the problem. I don't have a whole ...

Reading e.g. expose-object-from-class-library-using-wcf brings up an approach for using 2.0 class libraries by creating DataContractSurrogate objects to map 2.0 classes. Howev...
