Visual Studio common 2019 asks for proxy settings

Last week I had to reinstall everything on my laptop. And so I needed to download Visual Studio again. Befor Reinstallation I had Visual Studio Express 2017 installed. Now I installed Visual Studio Community 2019. I have a (surely!) running code. In this code I want to download an excel file from an internal sharepoint. This worked before without problems. But when I tried to run the code again it got the following error message:

Exceptional error during a web client request. Error in creating the web proxy specified in the configuration section system.net/defaultProxy.

I tried out this already: How to set proxy in visual studio 2015 I tried to put this lines into app.config and also to into devenv.exe.confi in my installation directory:

<system.net>
<defaultProxy useDefaultCredentials="true" enabled="true">
<proxy bypassonlocal="true"   proxyaddress=   "http://yourproxyaddress.net:8080" />
</defaultProxy>
</system.net>

But it didn´t helped. Then I received this error message:

The underlying connection has been closed: The connection to the remote server cannot be established. An invalid argument was given.

The earlier code did not need any proxy, it was running before without any problem. I invested already so much hours to try out different setting combinations. Have anybody an idea? Please help me.

Best wishes Begi

I found the solution: I stored the code under a network drive to prevent loosing again code in future. When I pasted the code back to my desktop, then it worked like before without any defaultProxy-settings. Thank you very much for your answers.
