Hello my fellow developers!

I am currently struggling with a problem in the latest Visual Studio 2017 Professional - Version 15.8(.1).

Since The Update to Version 15.8, I am unable to publish any Azure Function via Web Deploy.

Every time i press the "Publish" button, I simply get an error window saying: "Publish failed". The Output window stays empty, where normally I would get all the build and publishing output.

**What I've tired:**

* Cleaned the solution; deleted %temp%; deleted the publishing profile; reset the publish credentials in Azure; build it all again and import a newly generated publish profile: Same Error
* Uninstalled VS2017; Cleaned all remains; Reinstalled VS2017: Same Error
* Checked our Firewall, if anything gets blocked and even tried an exception for my workstation to allow all traffic: Same Error
* Tried publishing from a physically different Network: Same Error
* Stop the Function in the azure portal prior to publishing: Same Error
* In the azure portal: Delete an create a new and empty azure function to publish to: Same Error
* In the azure portal: Set the 'Function app edit mode' to Read/Write: Same Error
* Tried to hit the functions Endpoint-URL in the browser. No Problem.
* Tried to publish from a colleagues workstation with Visual Studio 2017 Pro Version 15.7.1: **Works fine - as used to**

**My Questions:**

* Am I missing something? Is there anything else I can try except installing an older version of Visual Studio, which would be my next step.
* Could this be a bug in the latest Azure Tools or even Visual Studio?
* Why is my Output window not giving me any information to address the failing publishing attempt? Am I missing some new option to activate this again?

I hope someone can point me in the right direction to solve this infuriating issue ;)
