The SDK that is being developed to process WeChat requests in. NET Core 1.0 with the most simplified operations, coresdk

A Development SDK that processes requests in. NET Core 1.0 with the most simplified operations, coresdk

The existing SDK library is in. NET Core 1.0 indicates that there is a lot of pressure, such as Deepleo. weixin. SDK and Senparc. weixin (even if one existing one is transferred. NET Core 1.0 initial project, but it is not available yet ). The former is lightweight and the latter is all lightweight, but in my opinion, the former is too lightweight. If I don't remember the parameters, it is useless if I don't click them, the latter needs to customize a processing method to execute related tasks, but the related types will never be redundant for me, I am not happy to use it. Therefore, you can develop an SDK library suitable for your own use by combining the two, which is open-source after the end of the project.

This Demo library has been released to NuGet (https://www.nuget.org/packages/OYMLCN.WeChat ),

If you are interested, you can use PM> Install-Package OYMLCN. WeChat to Install and use

Or add the reference version 0.0.1 of OYMLCN. WeChat to the project dependency.
