project : Web Application ...

I need to find error first . . .

why :

Error message parser: Error creating configuration section handler for FlowWebDataProviders: Could not load type 'FlowWebProvidersSection'.

?

by the way : syntax of nemerle (current language) is very similar C#, don't afraid to read the code... thank you

added : this is how I want to get section

ConfigurationManager.GetSection("FlowWebDataProviders")

Check your type AND namespace. I.e.

  <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" />
