Azure Function into Table Storage

To add a new entry to Table you should bind to IAsyncCollector instead of entity itself, then create a new entity and call AddAsync. The following snippet works for me:

var attributes = new Attribute[]
{
    new StorageAccountAttribute("..."),
    new TableAttribute("...")
};

var output = await binder.BindAsync<IAsyncCollector<MyTableEntity>>(attributes);     
await output.AddAsync(new MyTableEntity()
{
    PartitionKey = "...",
    RowKey = "...",
    Minimum = ...,
    ...
});
