Modify database access data in the app.config file after running the project’s "Publish"

Question

Hello, I created an application in C# and for access to the database I did the following procedure: In the app.config file I created the following:

<add name="MyDatabase"
    connectionString="server=192.168.10.100;user id=usuario;password=senha;database=nomeDataBase";providerName="MySql.Data.MySqlClient"/>

After that, in my code I called the connections like this:

var constring=ConfigurationManager.ConnectionStrings["Mydatabase"].ConnectionString;

So far so good, on the machine I developed this works perfectly, however, if I take it to another host and try to change the mysql server (linux - 192.168.10.100) by another network (linux also - 192.168.10.110) it does not connect, even changing the information of App.config. It’s like he still has the data from the test server. How can I change these values since I will have for example to use more than one server in different cases and keep compiling and publishing the project is sometimes an unnecessary job.
