This post shows you how to overcome the problems with installing the Dialogue forum package in your Umbraco site.

• Download the package from our.umbraco.org the version I have is dialogue v1.1
• Install it as a local package in the developer tab > Packages
• Click button to finish installation.
• Publish the forum and all of it's children.

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 3.0.0.0 to version 2.0.0.0

<dependentAssembly>
   <assemblyIdentity name="WebMatrix.Data" publicKeyToken="31bf3856ad364e35" culture="neutral" />
   <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>

Do another build, you should now be able to go to the forum page.
