Models. Optional. If your project is simple.

Views, optional, but generally requires an interface, which is included in the razor template.

Description.txt, which must be the version description of the plug-in. The content is as follows:

GROUP: Crawler
Friendlyname: Crawler
Systemname: NOP. plugin. Crawler
Version: 1.00
Supportedversions: 2.50

Notes.txt, which is the remarks of the plug-in, describes the File Location of the plug-in and some precautions.

Routeprovider. CS, the routing file, inherited from NOP. Web. Framework. MVC. routes. irouteprovider

View code

Using  System. Web. MVC;  Using  System. Web. Routing;  Using  Nop. Web. Framework. MVC. routes;  Namespace  Nop. plugin. crawler {  Public   Partial   Class  Routeprovider: irouteprovider {  Public   Void Registerroutes (routecollection routes) {routes. maproute (  "  Nop. plugin. Crawler  "  ,  "  Plugins/crawler/Index  "  ,  New {Controller = "  Crawler  " , Action = "  Index "  },  New [] { "  Nop. plugin. crawler.

UsingSystem. Web. MVC;UsingNop. Web. Framework. controllers;NamespaceNop. plugin. crawler. controllers {[adminauthorize]Public ClassCrawlercontroller: controller {PublicActionresult index (){ReturnView ("Nop. plugin. crawler. Views. Index");}}}
 

You have noticed that the view path in the returned view is the view path in the plug-in. Right-click the attribute set in the View index. cshtml, And the cshtml is compiled into the DLL.

You can also set the attributes of the entire plug-in by right-clicking on the plug-in project to set the output attributes.

Finally, set the properties of the referenced DLL file. In this way, other messy files will not be copied when the DLL file is output.
