Sample from generated template:

## Use collection expression for Create (IDE0303)
## This rule flags places where a Create() method or a similar method that's designated as the collection construction method (using the System.Runtime.CompilerServices.CollectionBuilderAttribute attribute) is used to initialize a collection and offers to replace it with a collection expression ([...]).
## Create() methods are common for the immutable collections, for example, ImmutableArray.Create(1, 2, 3).

## This rule requires more recent versions of the immutable APIs (for example, System.Collections.Immutable), which opt into the collection-expression pattern.
