Getting Fiddler to See you WCF Traffic

There are lots of articles on the internet if you search for WCF Fiddler however it’s not clear what the simplest path to follow is. For me, it turns out that just sprinkling a couple lines of code at the bottom of my windows forms app’s app.config file is all it took.  I got the tip from this post:

The magic lines are as follows:

      <proxy bypassonlocal="false" usesystemdefault="true" />

That’s it!  Now, Fiddler just sees the traffic.  I’m a happy camper.

  1. Thanks for your post. I’d prefer to comment that the price of car insurance varies greatly from one insurance plan to another, for the reason that there are so many different issues which contribute to the overall cost. As an example, the make and model of the car will have a significant bearing on the price. A reliable aged family automobile will have an inexpensive premium than a flashy expensive car.

  2. One thing I want to say is always that car insurance cancellation is a hated experience and if you are doing the best things as being a driver you may not get one. Many people do obtain the notice that they’ve been officially dropped by the insurance company and many have to struggle to get more insurance from a cancellation. Cheap auto insurance rates are frequently hard to get after the cancellation. Having the main reasons concerning the auto insurance cancellation can help individuals prevent completely losing in one of the most significant privileges readily available. Thanks for the concepts shared through your blog.
