Use EntityFramework6 to connect to the MySql database (db first mode)

Preparation tools:

VS2013, MySQL For VisualStudio 1.1.4, Connector/Net 6.8.3 (in Baidu Network Disk)

Run the following command in the package manager:

Install -- Package MySql. Data. Entity. EF6

If you directly add the ado.net object model, the following error occurs:

Note: There is a problem with the Provider generated in App. config. In this case, you need to manually add a red line:

<Provider invariantName = type =/>

In this case, you 'd better compile it first.

Then, add the ADO. NET object model.

Then it is the same as before.

I have been suffering from this problem for a long time and have forgotten it. Hope to help you get the same as me!
