Assembly assembly = Assembly.Load(path); These .dll files are outside of the solution, but there are classes in each of them that implement a common interface.

When I create classes, simple constructors tend to be the norm. On one of my current projects, a movie library, I have a Movie domain object. It has a number of properties, resulting in a constructor as follows: public Movie(string title, int year, Genre genre, int length, IEnumerable<string> actors) { _title = title; _year = ye...
I'm building a list of properties of a type to include in an export of a collection of that type. I'd like to do this without using strings for property names. Only certain properties of the type are to be included in the list. I'd like to do something like: exportPropertyList<JobCard>.Add(jc => jc.CompletionDate, "Date of Completion...

I'm a little unclear on what the proper way is to use DuplexChannelFactory in WCF. Following from convention, I have explicit Connect/Disconnect methods on my service contract to aid in management of the proxies, but I'm a little unclear as to what the client should be doing. Here's my impression of how things work. When initiating the ...

I'm currently using an XMLSerializer to serialize a list of a class of my own. One of the class's properties is an instance of a sealed class that does not have a parameterless constructor, so the XML Serializer refuses to serialize the class. How can I get around this? I need that property to be serialized. Is there some way for me ...
So, a couple of questions, actually: An int (Int32) is specified to be (obviously) 32 bits. What about an int? (Nullable<int>)? My gut tells me that it would be 32 bits for the integer plus 8 more bits for the boolean, but perhaps the implementation is more intricate than that. I would have answered my own question using sizeof(int?); ...

We are...
