asp.net 3.5 Extension (CTP)-Dynamic data metadata __net
Source: Internet
Author: User
Dynamic data is the most cool technology is that it provides a set of scaffolding framework, almost no code to build a data-driven Web program-database tables corresponding to the add, delete, modify, view function can be automatically generated. The metadata (metadata) generated by the Model of LINQ to SQL is its core.
Metadata can also provide more functionality, such as data validation. Instead of using a data validation control, you need to add an attribute, such as a range attribute, to validate the data range of an integer type in the properties of the entity class in model (the columns in the datasheet). Or use a Metadata.xml file to add the corresponding mapping information can also be implemented (disadvantage: When editing this file, vs without IntelliSense, is not very convenient)

There are still bugs in the CTP version-for example, after using the ReadOnly feature, the data can still be edited in edit mode:
