Roslyn provides a rich set of APIs for analyzing C# and Visual Basic source code, but constructing a context in which
to perform analysis can be challenging. For simple tasks, creating a Compilation populated with SyntaxTrees,
MetadataReferences and a handful of options may suffice. However, if there are multiple projects involved in the
analysis, it is more complicated because multiple Compilations need to be created with references between them.
To simplify the construction process. Roslyn provides the Workspace API, which can be used to model solutions,
projects and documents. The Workspace API performs all of the heavy lifting needed to parse SyntaxTrees from source
code, load MetadataReferences, and construct Compilations and add references between them.
