You can use the NuGet Package Manager extension.

After you've installed it, to add a package, press Ctrl+Shift+P, and type >nuget and press Enter:

Type a part of your package's name as search string:

And finally the package version (you probably want the newest one):

You can do it easily using "vscode-nuget-package-manager". Go to the marketplace and install this. After That

1) Press Ctrl+P or Ctrl+Shift+P (and skip 2)

2) Type ">"

3) Then select "Nuget Package Manager:Add Package"

4) Enter package name Ex: Dapper

5) select package name and version

6) Done.

Nuget Gallery provides a GUI similar to the full Visual Studio. See below.

How To Use:

Install Nuget Gallery from extension marketplace. Launch from the menu bar View > Command Palette or ⇧⌘P (Ctrl+Shift+P on Windows and Linux). Type Nuget: Open Gallery. The GUI above is displayed. You can filter just like in regular Visual Studio. Make sure the .csproj file checkbox is selected, select version from dropdown, and click install button.

UPDATE

Earlier versions, as noted in the comments, had an issue where the .csproj checkbox was not visible when a package in the csproj file was missing a version number like below.

<PackageReference Include="Microsoft.AspNetCore.App" />

This has been fixed in newer versions of the extension so if you have an older version with this issue, please update it to the latest version.

---

Open extensions menu (Ctrl+Shift+X), and search .NuGet Package Manager.

---

Example for .csproj file

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="1.1.2" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.2" />
    <PackageReference Include="MySql.Data.EntityFrameworkCore" Version="7.0.7-m61" />
  </ItemGroup>

Just get package name and version number from NuGet and add to .csproj then save. You will be prompted to run restore that will import new packages.

Install NuGet Package Manager Ctrl+Shift+P on Windows or Command+Shift+P on Mac Search for NuGet Package Manager: Add Package Enter package name i.e. AutoMapper Select package & version Restore if needed

---

If you're working with .net core, you can use the dotnet CLI, for instance

dotnet add package <package name>

---

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.

First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).

But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:

dotnet restore Project-File-Name.csproj

And that installs the package

---

Modify your project.json or *.csproj file. Add a dependency entry with the name of the package and the version desired.

JSON example:

{
   "dependencies" : {

     "AutoMapper": "5.2.0"
   }
}

---

Go to folder that have a sln file. Open a terminal (like cmd)

dotnet add package <package name>
