I searched everywhere, but could not find a solution that worked for me.
We've created a default document library, changed it a bit and saved it as a new document library template from the user interface. I can create document libraries based on this template successfully.
However, I have some CSOM code that creates a library automatically for me. It is now based on the template "101", which is the default document library. I want to create the library in code based on my custom document library.
I understood that I need a custom list template ID (which should be > 10000), but I cannot find out how I can find the custom list template id's. I found commands that list the default list template id's (i.e. 100, 101) but not the custom list template ID's. How can I find the custom list template ID's?
