Why is it illegal to have a private setter on an explicit getter-only interface implementation?
I tend to favor explicit interface implementations over implicit ones, as I think programming against the interface as opposed to against an implementation, is generally preferable, plus when dealing with web-services it is often a necessity.
That…

More specifically, if I have:
public class TempClass : TempInterface

int TempInterface.TempProperty
{
get;
set;
}
int TempInterface.TempProperty2
{
get;
set;
}
public int TempProperty

Explicit interface implementation cannot be virtual
For the record, I've already seen this connect item but I can't really understand what would be the problem in supporting this.
Say I have the following code:
public interface IInterface
{
void Method();
}
public class Base : IInterface
{

Why would a class implement IDisposable explicitly instead of implicitly?
I was using the FtpWebResponse class and didn't see a Dispose method. It turns out that the class implements IDisposable, but does so explicitly so that you must first cast your instance to IDisposable before calling Dispose:
// response is an…

call a base-class explicit interface method in F#
Ok I derive a type B from a base class A.
A implements IDisposable explicit but I have to do additional cleanup in B, so I implement IDisposable in B:
interface IDisposable with
member i.Dispose() =
// ... additional work

Why does calling an explicit interface implementation on a value type cause it to be boxed?
My question is somewhat related to this one: How does a generic constraint prevent boxing of a value type with an implicitly implemented interface?, but different because it shouldn't need a constraint to do this because it's not generic at all.
I…

Is there a way to invoke explicitly implemented method/property via reflection in .NET?
I need to be able to determine if a given method or property comes from a particular interface and is explicitly implemented.
Has anyone done this and is it actually possible to get this information by the means of .NET reflection?
Update
As can…

Explicit implementation of IDisposable
Although there are quite a lot of Q&As regarding IDisposable to be found on SO, I haven't found an answer to this yet:
I usually follow the practice that when one of my classes owns an IDisposable object then it also implements IDisposable and calls…

Why do explicit interface calls on generics always call the base implementation?
Why do explicit C# interface calls within a generic method that has an interface type constraint always call the base implementation?
For example, consider the following code:
public interface IBase
{
string Method();
}
public interface…

Why is HashSet.IsReadOnly explicit?
This
var h = new HashSet();
var r = h.IsReadOnly;
does not compile. I have to do
var r = ((ICollection)h).IsReadOnly;
why wasn't IsReadOnly implemented normally?
(I'm not asking how, but why)

Fortran - explicit interface
I'm very new to Fortran, and for my research I need to get a monster of a model running, so I am learning as I am going along. So I'm sorry if I ask a "stupid" question.
I'm trying to compile (Mac OSX, from the command line) and I've already…
