What is the Embedded Interop Types check mark in VS responsible for?
On Office builds, there is a check mark like this: Embed Interop Types
What is it responsible for? With this check mark, it is not possible to copy the assembly locally.
I noticed that if you disable it, some operations with office objects require an explicit type conversion.

This option was introduced to remove the need to deploy very large interop assemblies (PIAs - > Primary Interop Assemblies).
Enabling this option allows you to embed managed code to communicate with unmanaged assemblies in your assembly, but instead of embedding all the interop assembly code, it only embeds the elements that are actually used in your assembly. the code.
