Permanently remove machine-wide package source - visual-studio

Question

I've recently uninstalled Service Fabric and its SDK from my machine. However, it has left behind a machine-wide package source:
Microsoft Azure Service Fabric SDK
C:\Program Files\Microsoft SDKs\Service Fabric\packages
This folder no longer exists. It is causing my build to fail. Unticking this option as an available source doesn't seem to persist between sessions.
How can I permanently remove this package source?
UPDATE
In the Visual Studio options, delete is not available for this package source. I can untick it, but that doesn't seem to be persistent.
My NuGet.config doesn't reference it either. I can't find another NuGet.config on my computer.
%AppData%\NuGet\NuGet.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
<add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\" />
</packageSources>
<packageRestore>
<add key="enabled" value="True" />
<add key="automatic" value="True" />
</packageRestore>
<bindingRedirects>
<add key="skip" value="False" />
</bindingRedirects>
<packageManagement>
<add key="format" value="0" />
<add key="disabled" value="False" />
</packageManagement>
</configuration>

Answer 1

I found that deleting this file (as an Administrator) solved the problem. It must have been missed by the Service Fabric uninstaller.
C:\Program Files (x86)\NuGet\Config\ServiceFabricSDK.config

Answer 2

just delete unwanted .config files in C:\Program Files (x86)\NuGet\Config

Answer 3

I had this same issue on an Azure Devops build machine, which was causing a build failure when it would build locally and on other build machines. Found this file here: C:\Program Files (x86)\NuGet\Config\nuget.config which contained the offending packages.
deleted the nuget.config file at that location and worked like a charm. Hope this helps someone.

Answer 4

How can I permanently remove this package source?
When we create Service Fabric application with Visual Studio, we always receive following message in the output window:
An error occurred attempting to configure NuGet to reference the
Service Fabric SDK package location as a package source. To fix this,
you can manually add a NuGet package source in the Options window and
setting it to the following path: C:\Program Files\Microsoft
SDKs\Service Fabric\packages.
You may configure nuget setting as suggestion.
So, to permanently remove this package source, you can open the visual Studio Tools->NuGet Package Manager->Package Manager settings->Package Source:
Select that nuget package source and delete it. Or you can open the configuration file nuget.config directly from path C:\Users\<UserName>\AppData\Roaming\NuGet\nuget.config and delete it:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
...
<add key="Test" value="C:\Program Files\Microsoft SDKs\Service Fabric\packages" />
</packageSources>
<packageRestore>
<add key="enabled" value="True" />
<add key="automatic" value="True" />
</packageRestore>
...
</configuration>
Move the package source <add key="Test" value="C:\Program Files\Microsoft SDKs\Service Fabric\packages" />.
Hope this helps.
