How to install C# client library, particularly Google Cloud Text to Speech?

Question

I'm trying to use Google Cloud services such as Text-To-Speech in a Unity app. On the quickstart page I've done the Before You Begin stuff. However, I can't "Install the Client Library". The provided line is:

Install-Package Google.Cloud.TextToSpeech.V1 -Pre

However, when I put this into my terminal it says "'Install-Package' is not recognized as an internal or external command, operable program or batch file."

I tried with Powershell too but got "Install-Package : A parameter cannot be found that matches parameter name 'Pre'.

At line:1 char:46

• Install-Package Google.Cloud.TextToSpeech.V1 -Pre

• ~~~~

• CategoryInfo : InvalidArgument: (:) [Install-Package], ParameterBindingException

• FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.PackageManagement.Cmdlets.InstallPackage"

I've tried searching online but it seems like I'm just missing a crucial step or something. Is there supposed to be anything I do before trying to install the client library? Am I doing it in the wrong place? Help appreciated, thanks!

Install-Package is a feature of the Nuget package manager console. You can open this from Visual Studio by following these steps:

1. Select the Tools menu
2. Select NuGet Package Manager
3. Package Manager Console

You can now run that command in the resultant window.

Alternatively, you can install it directly from the UI by selecting "Manage NuGet packages for the solution..." instead of "Package Manager Console".
