Composite R2R images.

[Pavel Voronin]

ASP.NET Core Composite images provide a smaller size on disk while keeping the performance of the default ReadyToRun (R2R) setting. The caveat is that the composite images have tighter version coupling. This means the final app run on them cannot use handpicked custom versions of the framework and/or ASP.NET assemblies that are built into the composite binary. For a full technical description on how the composites work, we have a feature
doc here.

How do I find out which assemblies and of what version?

The version is the same version as the rest of the product.

Thanks. So effectively I should not even need to reference these assemblies separately as they are part of ASP.NET metapackage.

Right. Zero user gesture required. It's all automatic.
