NuGet search shows package available but install says it's not found

I'm trying to get jQuery-vsdoc. Find-Package jQuery-vsdoc returns what I expected. But Install-Package jQuery-vsdoc state it's unavailable.

How can Find-Package work but Install-Package says it's not found?

Isn't Find-Package supposed to only show what can be found?

This is exact output from the package console

Solution

  • Based on my test, i found that this jQuery-vsdoc package not only supports .NET SDK but also .NET Framework.

    1.Target .NET Framework that uses packages.config by default.

    enter image description here

    2.Target .NET that uses PackageReference.

    <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
     <TargetFramework>net8.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="jQuery-vsdoc" Version="2.1.0" />
  </ItemGroup>

    enter image description here

    For this issue, here are suggestions you can troubleshoot:

    1.Clear Nuget Storage. Go to Tools > NuGet Package Manager > Package Manager Settings. In the settings dialog, click on Clear All NuGet Storage.

    2.Try to install other nuget packages for test and confirm if this issue only occurs with a specific package or all packages.

    3.Ensure that your internet connection is stable and you have access to nuget website.

    4.Try to download the package directly from nuget website and put the package into your local folder then install this package from local folder to see if you can install this package successfully. enter image description here
