This post shows you how to overcome the problems with installing the Dialogue forum package in your Umbraco site.
Build the project
If you get this error:
Cannot find reference for Microsoft.Web.Helpers
Then install the following NuGet Packages using the NuGet Package Manager Console
PM> Install-Package Microsoft.AspNet.WebHelpers
PM> Install-Package WebMatrix.Data
PM> Install-Package WebMatrix.WebData
When you have done this, do another build and try to go to the forum.
You may then get another error about WebMatrix.Data
You need to edit the web.config file at the root of the site to redirect version 22.214.171.124 to version 126.96.36.199
<assemblyIdentity name="WebMatrix.Data" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-188.8.131.52" newVersion="184.108.40.206" />
Do another build, you should now be able to go to the forum page.
