Hello,
When the blank page appears can you login to the backend of the sample by typing /sitefintiy after the url?
The asp development server loads lots of time because there is no database created for the sample all the sample content is created when you first start the project, all settings for creating pages, templates, news and other content is stored in Global.asax.
In App_Data/Sitefinity/Configuration/DataConfig.config there is a connection string to the SQL Express database created for the sample can you check if the database exist?
It should be available if you have SQL Server Express instance on the machine where testing the samples.
If SQL express is not present open the sample in Visual studio edit the DataConfig file to point to already created empty SQL Server database where to store the data. Here is a sample connection string that connects to TestSDK databse
After this view SitefinityWebApp (which is the web application project for sitefinity, other projects in the solution are the widgets for the sample) in the browser by starting the local development server All the best,
