Azure functions CosmosDB attribute in Visual Studio 2017

Question

I`m trying to make working pilot project with Azure Functions and CosmosDB input binding. I have updated my Visual Studio 2017 to latest pack (15.5.5). Also I have installed latest Azure Functions SDK.

After I have added to Azure Functions project new CosmosDB trigered function I see the following picture after build:

Error after build in VS
Nuget packages

There are no any documentation about CosmosDBTrigger. Maybe you met this class before and can tell me where to find this magic lib in nuget, which will work for me (in which this CosmosDB attribute is defined)?

PS: DocumentDB attribute from azure web jobs SDK not working at all, as soon as if function has this attribute azure don`t see this function at all. Queue binding functions works for me ok.

Thank you.

CosmosDBTrigger attribute is introduced only in version 1.1.* of Microsoft.Azure.WebJobs.Extensions.DocumentDB NuGet package.

Unfortunately, this version is still in beta (1.1.0-beta4 as of today), so you need to tick Include prerelease checkbox in your Visual Studio to use it.
