1. Open this file: "C:\Users{YourUsername}\AppData\Roaming\NuGet\NuGet.Config"

---

2. First try changing content of this 'NuGet.Config' file to default state:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
  </packageSources>
</configuration>

• If everything is okay with Visual Studio's NuGet then dont continue.

2.1. If same problem happens again try changing content of 'NuGet.Config' file with this:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <packageSources>
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    </packageSources>
    <config>
        <add key="signatureValidationMode" value="accept" />
    </config>
