Thank you for your interest in GroupDocs.Annotation.
1. Because your project is ASP.NET MVC project, we suggest you to download and install a “GroupDocs.Annotation C# Demos” package. This package contains a solution that in turn contains several projects, including the “Groupdocs.Demo.Annotation.Mvc” project. This is what you need.
2. The “Groupdocs.Demo.Annotation.Mvc” project uses SQL Server Compact. As I understand, you want to use SQL Server (standard). In order to do this you need to perform two steps:
2.1. You need to prepare a SQL Server database, which should contain specific tables. Here you can find the required structure. Because you are using GroupDocs.Annotation version 1.8, you should use a database schema from the “GroupDocs.Annotation ver 1.5, 1.6, 1.7 and 1.8 database schema script” section.
2.2. You need to modify the connection string in your web.config. Here you can find it (section “1. General guide” item 3).
3. All documents, which you want to display and annotate, should be placed in the root storage folder. You can specify this folder by yourself in the “Groupdocs.Web.Annotation.WidgetFactory.Initialize” method. By default GroupDocs.Annotation uses the “App_Data” folder as the default root storage, but you can re-assign it.
