Hello. Today I have a WCF question, though it probably pertains to other Networking models in .NET as well.

I'm building a workflow app to investigate the technology. I can't decide whether to go for a web service (and a technology with which I'm basically familiar) with WebServiceInputActivity's or WCF and ReceiveActivity's (and a new technology that I'll have to learn). Are there any major reasons to go either way? Clarification: Are the...

I'm trying to connect to a web service that requires me to sign with a certificate before I connect. In WSE 3.0, all I had to do is create a certificate policy and choose the "sign only" radio button. That worked fine in WSE 3.0, but I want to use this on Visual Studio 2008+ (wse 3.0 only supports 2005). In order to get around the 2005 ...

A Guide to Designing and Building RESTful Web Services with WCF 3.5, this article explains the foundations of REST and how it relates to WCF. MVC uses REST as the architectural model. I am guessing one can use the .NET MVC to create web applications that have both a front end and an API point, but I am not sure if the safe way of buildi...
I'm just about getting into WCF; but from what I've read so far, like the sample scenarios I found on MSDN and some other sites, I can do all that with web services and applications that call those web services. So why the need for an elaborate layer like WCF? Most of the comparisons I've googled for explain it more from a programming p...

WCF has lots of limits imposed on it to protect against DoS attacks and other developer brainlessness. What are these limits? And how can they be overriden?
