Answer 3

The connection string section has the following definition and is case-sensitive:

<connectionStrings>
     <add name="conexionsql" connectionstring="Data Source=FCH-DESARROLLO;Initial Catalog=DesaInterno;Integrated Security=True;User ID=usuario_de_conexion;Password=a"
 providerName="System.Data.SqlClient"/>
</connectionStrings>

Answer 4

This is because the keys are case-sensitive and you have it all lower-case connectionstrings, simply change to the correct case connectionStrings (note upper-case S).

Complete config (with redundant items removed) now looks like this:

<?xml version="1.0" encoding="UTF-8"?>

  </connectionStrings> 

  <system.web>
    <compilation debug="true" targetFramework="4.5">

        <add assembly="*" />
