This is optional if the However the constructor taking a connection string as first parameter looks like this : Is there another way to initialize the BlobClient with Blob Uri + connection string ? If the resource URI already contains a SAS token, this will be ignored in favor of an explicit credential. A blob can have up to 10 tags. When copying This can either be the name of the container, I can do it like that : But I do not want to use the StorageSharedKey in this case.
