I just downloaded YAF yesterday. I opened the web site in VS 2013 and it looks like everything works perfectly. But I was looking for documentation about the product. Here are my questions:

1. I have an existing ASP.Net web site that works great. I want to add a new menu item on my master page for Forums. When Forums is clicked, I want to call the YAF web site. Not sure how to do this. Up till now, all my web sites were standalone sites and not accessing other sites.

2. Is there some documentation of the SQL database?

3. This is probably related to question #2 as it's probably database-driven, but how do I tailor YAF for my specific forum topics?

Thanks,

Bob

1- What has been done is you put all of YAF's files (minus the BIN directory) into a directory called "forum"... then in your site.master you add a link to yourdomain.com/forum ... you will have to edit the default.aspx page to include your specific asp.net project... for example, my default.aspx page code is below, this is in my /forum directory.

<%@ Page Title="Forum" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"  CodeBehind="Forum.aspx.cs" Inherits="PackersHome.Forum" %>
<%@ Register TagPrefix="YAF" Assembly="YAF" Namespace="YAF" %>


<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
   	<br /> <YAF:Forum runat="server" ID="forum" BoardID="1" />
</asp:Content>

2- I don't have an answer for this

3- sorry, i don't know what you're asking, could you elaborate and i could try to help

It is an error to use a section registered as AllowedDefinitions='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. When I click on the error it highlights the forms authentication section:

I never had 2 web.config files in the same project so not sure what to do.

Did you create "Folder" or "Forum"? I am not trying to be nit pick, but I think you said you created Folder, but pointed the url to /Forum/...

Thanks,

Bob

Did you deleted one web.config? the one in the forum folder?

Check the integration guide for more info...

https://github.com/YAFNET/YAFNET/wiki/YAF.NET-Integration-in-to-an-existing-ASP.NET-Application 

The type or namespace 'YAF' could not be found (are you missing a using directive or assembly reference?)

var identity = manager.CreateIdentity(user, DefaultAuthenticationTypes.ApplicationCookie);

ANd here is the error:

Error 5 'Microsoft.AspNet.Identity.UserManagerExtensions.CreateIdentity()' is not supported by the language C:\Users\XXXXXXX\Documents\Visual Studio 2013\WebSites\DotNetDevelopersFlorida\App_Code\IdentityModels.cs 44 36 DotNetDevelopersFlorida

I can only guess in that case because i never used the new ASP.NET Identity, but my guess is that that both are not working together (identity whith the old asp.net membership).

There is a possible solution posted here:
