问题 Background: My WCF application has to call a service that does not have any concurrency checking in it. It is a service created by a third party and getting them to add concurrency checking may not be possible. I can ensure that the only way to call the third party service is via my WCF application. So I am considering putting concurrency checking in my code. To do this, I will use an identifier that uniquely describes the data being modified. The idea is that if one call to the service is

问题 I have a WCF layer and my Domain Model is behind this WCF layer. I am using Nhibernate as an ORM tool and all my business logic/ Data Access etc will be behind this WCF layer. I am exposing DTO to my clients. I have below questions 1) Should i create DTOs? is there any harm in exposing entities directly to wcf clients as my entities would also have business logic methods also in doing so i would have to corrupt my entitiy object with WCF attributes which i think is not good? 2) If i expose

问题 I'm using the default configuration of Visual Studio to host my wcf service in a development scenario. I want to add a net.tcp endpoint, but I always get an error. 回答1: According to this FAQ, this functionality is not available in IIS Express: Here's the extract of the relevant question from the FAQ: Q: Does IIS Express support non-HTTP protocols such as net.tcp or MSMQ?
