This one works for me:

using (var ctx = await _pnpContextFactory.CreateAsync(new Uri(_absSiteUrl)))
{
	var list = await ctx.Web.Lists.GetByTitleAsync("Site Pages");
	var rootFolder = await list.RootFolder.GetAsync();
	var folder = await rootFolder.AddFolderAsync(folderName);
	return folder.ServerRelativeUrl;
}

Hello @piteerus,

Thanks for reporting this, I think we may probably address that issue making sure the RootFolder is properly loaded and initialized in the AddFolderAsync method. We’ll need to think about the best way to handle it ( cc @jansenbe ).

[EDIT] After double-checking with Bert, it indeed looks like this one I mentioned is neither working… We will think about it and most likely address that issue.

The following snippet is from our passing unit test

IFolder parentFolder = await context.Web.Lists.GetByTitle("Documents").RootFolder.GetAsync();
IFolder newFolder = await parentFolder.AddFolderAsync("TEST");

It’s a bit less fluent style…, but this one works

Again, thanks for trying out the PnP Core SDK !
