error creating the web proxy specified in the 'system.net/defaultproxy' configuration section

Question

I receive the error from a third party application exe. The Application is only a exe, no config file or others.

\"error creating the web proxy specified in the \'sy

Answer 1

This error is somehow related to the .Net framework you're building against.

I created a simple test app to perform a WebRequest. If I set the target Framwework to 4.0, I get this error. If I then set it to 3.5, without changing the code, my request works fine.

It does not directly solve your issue, as you probably cannot change the external application you're using, but I hope this may be useful for people who look for the same error message.
