I had to apply these settings to make Kooboo work on my machine connecting to MongoDB on my VM:
For the MongoDB.config (when you follow the instructions to set it up http://www.kooboo.com/Documents/Detail/CMS/v3/MSSQL-SQLCE-RavenDB-and-MongoDB ), I copied it to:
And you may have to copy it to C:\kooboo\Kooboo_CMS\Kooboo_CMS\bin as well. (my installation was a little flaky)
You’ll have to build the project (in VS2010) if you already ran the site (the default data store is XML files).
When all is set and done, make sure that the db was created on MongoDB. In this case, it created the db samplesite.
