Automatically version Asp.net Core Web App - asp.net-core-2.0

Question

I have a web application in Asp.Net Core 2.0. In the csproj I have a version number with pattern 1.0.0.0. I would like when I compile with VSTS that the pattern becomes 1.0.0.$Build.Id, but I cannot find a way to do this.
I tried the Update Assembly Info VSTS extension this task but it does not work:

Answer 1

There are many extensions in marketplace that can update assembly info, such as Assembly Info.
You also can do it through PowerShell script with PowerShell task: Auto assembly versioning in Visual Studio Team Services (or VSTS) build.
