Data Abstract for .NET comes with two samples that demonstrate the use of Briefcases to persist client data in a Data Abstract program. They show how to retrieve data from an instance of Relativity Server, store the retrieved data in a briefcase, set properties on a briefcase and reloading it again from disk. The Desktop sample is interactive where the Console based sample isn't.
The samples are typically located in
C:\Users\Public\Public Documents\RemObjects Samples\Data Abstract for .NET there you will find folders for each programming language.
Sample 1: Desktop based program
Sample 2: Console based program
The Console Sample is available only in C#.
