public class App
{
public static Page GetMainPage ()
{
return new ContentPage {
Content = new Label {

},
};
}
}

MihaMarkic's post here led me to the right answer. For each project in your solution you'll need to do the following:
This is the workflow that got it working on my Mac. I'm not sure what the exact steps are for you PC users out there.
works same way on PC - once I realized where to look for step 2 -- MENU "Project"; which has menu item "Add Nuget Packages..." for step 3.

for me, the "Add Nuget Packages.." doesn't work for me, so i clicked the "Update Nuget Packages..." it works fine.. thanks @eckyzero

I just had to add the Xarmin.Forms.Addin.dll in app's references. :) (Thanks @sam holder your hint in the comments led me to the answer.)
glad you got it fixed

Most of this answer is a thank you, rather than an actual answer. It would probably be better to lead with the solution, then credit the other user with leading you in the right direction. It also wouldn't hurt to flesh out the steps you took to solve the problem.

Tell us how you fixed it please. "Thanks" sucks.

This is the link to know how to add reference.And you just have to add Xamarin.Froms.Addin library to get through this error.

Where would "Xamarin.Forms.Addin" be located?

Do the following:
Select the solution & right click
Go to Restore Manage Nuget Packages
You are ready to work with xamarin.forms :)
After updating I needed to close and re-open VS (VS2017 in my case) before the references showed back up.

Do the following
3.Go to control panel select programs and features and right click xamarin choose repair.
4. Start xamarin studio again.
This happened when I removed the Xamarin.Android.Support.v4 and Xamarin.Forms library in order to downgrade to an earlier version. I got it working again by resetting the Droid packages.config to:
Xamarin.Android.Support.v4
Xamarin.Forms
packages.config
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Xamarin.Android.Support.v4" version="22.1.1" targetFramework="MonoAndroid44" />
<package id="Xamarin.Forms" version="1.4.2.6355" targetFramework="MonoAndroid44" />
</packages>
Then right-click the Droid Packages folder to Restore missing packages.
The final step is to add the References > From Packages to the *.Droid.csproj
Packages
References
From Packages
<Reference Include="Xamarin.Android.Support.v4">
<HintPath>..packagesXamarin.Android.Support.v4.22.1.1libMonoAndroid403Xamarin.Android.Support.v4.dll</HintPath>

Look for your Target. Some targets aren't compatible with Xamarin.
I had to uninstall and reinstall Nuget Xamarin.Forms in both the Android and PCL library.
Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
have you referenced the dll which contains Xamarin.Forms in your project? (presumably something like Xamarin.Forms.dll)
