SharePoint extension technology experience

After two months of work, I wrote a one-month SharePoint application. I found that SharePoint development can do everything I want,

But first, we need to understand the SharePoint technology system. Second, we need to study the SharePoint SDK in depth, and finally Asp.net.

1. Feature and feature can be used as extensions to complete the work of the entire site. The key is that layout and development are much easier than other solutions.

2. webpart

3. User Controls

4. content type field type extension, which is very useful. Through field extension, verification and other functions can be performed.

5. Events (eventhandler) may sometimes become invalid during the arrangement, and the customer experience for verification is poor.

6. I don't know about HTTP modal.

7. The server control is being written and has not been configured yet.

8. No application for Web servies

9. workflow is not ready yet

It's just a preliminary application, and there is still a lot of depth that hasn't been tapped.

It is much easier to replace caml by querying the splistitemcollection using LINQ.

Ajax has not been applied yet, and I also want to explore the application of WCF on SharePoint.

As a platform, Sharepoint is very convenient if its logic is simple.

However, the interface logic of the business system is very complicated, especially if the replacement method is not used, I cannot solve the problem by extending the checksum function of the form automatically generated by lists such as new, edit, and display, the event method is poor, and sometimes it will fail. Which of the following experts can I ask.
