Question: 1

What is the difference between static or dynamic assemblies?

Assemblies can be static or dynamic. Static assemblies can include .NET Framework types (interfaces and classes), as well as resources for the assembly (bitmaps, JPEG files, resource files, and so on).

Static assemblies are stored on disk in portable executable (PE) files.

You can also use the .NET Framework to create dynamic assemblies, which are run directly from memory and are not saved to disk before execution.

You can save dynamic assemblies to disk after they have executed.

Question: 2

Differences between dataset.clone and dataset.copy?

On the other hand dataset.copy, copies both the dataset structure and the data.
