If you want to remove the Microsoft Teams Banner on your SharePoint Site, the only thing you need is to set a web property on a site: TeamifyHidden=TRUE. I’ll give you some guidance below. But before you do that, consider following:

• If there is already a team created for a group connected site, the prompt won’t show up. Why fix something that is not a problem?
• Only group owners will get the prompt, if they are few and they know what it is, it is better to let them to decide whether to create or not to create a team.
• Only licensed users within your organization will be shown that choice. No external users or users without a license.
• And the most important part: if any site owner selects “Don’t show me again” it will stop popping up for all other site owners. If you happen to have a manual step in the group creation process, then you can just click it away.

Do you prefer REST over CSOM as I do? I’ll skip the whys. Andrew Connell put it already in wrtiting so nicely. Well, if you do prefer REST, then you must have discovered some shortcomings of REST, or its incompleteness compared to CSOM. I think of:

1. Inability to filter items based on multivalued taxonomy fields
2. Inability to filter items based on user fields where user is added through a group, rather than directly, e.g. AssignedTo=[Me] combined with a SharePoint group.
3. …

In such situations I was forced to use CSOM. Until yesterday. Yesterday I learned that we can actually use CAML queries in REST requests.   This enables using REST in all situations. The REST API is still developed and many features are added. Maybe a particular operation that needs a CAML query today, can be supported in the core REST API and can be easily refactored then. But until then, we can use CAML queries in REST requests. Here are the important things about it:

As a SharePoint architect or a SharePoint developer, you must have been thinking about the benefits/limitations of SharePoint apps a lot. I want to point out one of them today, which is very important: using custom webservices deployed to SharePoint inside apps. That is impossible and it is designed to be so due to the security architecture in the sharepoint app framework. I have read much about SharePoint apps (books, whitepapers, blog posts) and stumbled over these two contradictive statements:

SharePoint 2013 REST API has been enhanced and extended. The old _vti_bin/listdata.svc is still there, but the new api for working with lists and list items is much more and obviously a part of a bigger api: _api/web/lists Yesterday I saw an interesting question on SharePoint StackExchange:

• “500: Internal Server Error” when trying to add a simple text file as an attachment via SharePoint 2013 REST API

The instructions in the MSDN resource are not so detailed, the cannot be. The guy who asked the question did as it stood in the examples. But sometimes solutions for SharePoint need some small adjustments :) Here is the simplest code to create an attachment in plain text for a list item 1 in the list called List1 in the root web. That’s it. But it works: [sourcecode language=“javascript”] var content = “Hello, this text is inside the file created with REST API”; var digest = $("#__REQUESTDIGEST").val(); var composedUrl = “/_api/web/lists/GetByTitle(‘List1’)/items(1)/AttachmentFiles/add(FileName=‘readme.txt’)”; $.ajax({ url: composedUrl, type: “POST”, data: content, headers: { “X-RequestDigest”: digest } }) [/sourcecode] This example is of course just for demonstration. It uses only hard-coded values. But it shows how simple it is to create a list item attachment using SharePoint 2013 REST API and “upload” plain text asynchronously to the server.

SPServices is a great tool, really nice work, Marc Anderson (@sympmarc). It has been there all the time I have developed for SharePoint. But the fact that you work with XML and you must parse the attributes (!) was the reason why I prefered listdata.svc and Client Object Model, where you get objects in JSON or you have a nice API to get objects and their properties. But there is an area where SPServices are really the best tool: SharePoint Web Services which only understand SOAP like SocialDataService.asmx.

In one of my previous posts I showed how to retrieve data from listdata.svc with jQuery $.getJSON method. Getting data is very simple, listdata.svc provides a powerful restful interface with filtering, expanding and other features. Read the best and short introduction to listdata.svc by Suneet Sharma or a more detailed and technical article about filters, functions and operators by Mike Flasko at Microsoft with short examples here. Now back to listdata.svc in the SharePoint environment. Corey Roth provides a good images and sample results. For REST the “http verbs” are very important: GET, POST, PUT, DELETE.. SharePoint RESTful interface defines these verbs like that:
