Erro ao criar sistema cliente servidor.

Olá amigos desenvolvedores.

Estou tendo problemas ao criar uma aplicação cliente servidor. Estou tentando conectar a um servidor sql e está dando o seguinte erro.
Adicionei uma imagem em anexo com o erro.

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
