How do I Enable Crud and other properties in ListViewWebPart programmatically

Question

In SharePoint (SharePoint Designer) 2010, to use a custom list in different sites, we used the resource to export the to site gallery. So the list became a list web part where I could use all the available resource list created on the
same site (examples: list settings, crud, views ...)
We need to provide the same functionality in 2013 programmatically for the user. We try ListViewWebPart class to use, but the resources of crud on the list were not available.
I Would like to how do I enable crud and other properties in ListViewWebPart or if there is another class that does it.
Thanks in advance
