So, I realize that there are a lot of questions on here pertaining to this problem, but none seem to be the same as to what I'm dealing with. I had to delete my dataset out of visual studio and bring it back in. After doing so I got the error. I'm using mysql as a backend, so I'm using the dotconnect for mysql extension for visual studio. Everything was working fine until I did this step. Here is my app.config file:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
</configSections>
<connectionStrings>
<add name="RMSteel.My.MySettings.RMSteelConnectionString" connectionString="User Id=rmsteel;Password=password;Host=192.168.0.46;Database=RMSteel;Persist Security Info=True"
providerName="Devart.Data.MySql" />
</connectionStrings>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
</configuration>
Whenever I use my connection I use the name RMSteel.My.MySettings.RMSteelConnectionString, since this is auto-generated (I assume by dotconnect). I am fairly far in this project and would like to find a fix using this connection string, so I don't have to rewrite that much. Thanks for any help, and if you'd like me to post more code, I can.
