Let's say I have a common WCF service and console app project that do not change across client specific deployments. I have some interfaces in the common projects that are implemented by specific client code. The client code obviously changes from client to client. I'm thinking this would be an appropriate use for an IoC container. In my...

Is there a way to control this with attributes without implementing IXmlSerializer on DerivedType? ...
I want to understand why the protocol buffers solution for .NET developed by Marc Gravell is as fast as it is. I can understand how the original Google solution achieved its performance: it pre-generates optimized code for object serialization; I've written some serialization by hand and know that it is possible to write pretty fast co...

I can authenticate/sign in without a problem. But once i've done that, I have no idea how to send a simple text message to two other users. Do those users need to b...

I'm looking at some code written by a former employee where I work and I'm noticing that he sometimes uses hexadecimal notation, and other times decimal. Since he's long gone I can't ask him why, so I hope someone here could take a look and enlighten me. command.Parameters.Add("PI_EMPLOYEE_NUM", OracleDbType.Varchar2, T...

I'll post a sample of my code below in hopes that someone has some time to make some recommendations for my example. public AMPFileEntity(string filename) { tr...
Can the ArrayList below be initialized directly without the need for aFileExt string array? private static string[] aFileExt = {"css", "gif", "htm", "html", "txt", "xml" }; private System.Collections.ArrayList alFileTypes = new System.Collections.ArrayList(aFileExt); The line below is the goal, but my .Net Compiler does not...

My question is how does the SqlConnection know that a reader is attached to it. There is not a public property or any...
