Disabling a specific compiler warning in VS Code

I was able to get this to work. My solution looks something like this:

<PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <RuntimeFrameworkVersion>2.1.1</RuntimeFrameworkVersion>
    <NoWarn>0169;8019</NoWarn>
</PropertyGroup>

<NoWarn> is PascalCase rather than camelCase, and the element is nested inside of a <PropertyGroup>.
