I have created database-first from entity framework,the framework created connection string in my web.config like

<connectionStrings>
    <add name="projeEntities" connectionString="metadata=res://*/Models.EntityFrameworks.ProjeModel.csdl|res://*/Models.EntityFrameworks.ProjeModel.ssdl|res://*/Models.EntityFrameworks.ProjeModel.msl;provider=Npgsql;provider connection string="Host=127.0.0.1;Database=proje;Username=postgres;Password=sdt2018; Persist Security Info=True"" providerName="System.Data.EntityClient" />
  </connectionStrings>

but this is not working ,visual studio gave this error

System.Data.Entity.Core.EntityException: 'The underlying provider failed on ConnectionString.'

When I change web.config like

<add name="projeEntities"
           connectionString="Server=127.0.0.1;Database=proje;User Id=postgres;Password=sdt2018;"
           providerName="Npgsql" />

visual studio gave code first error but I am working on database first. Can you help me?
