Find an EnvDTE.CodeType from a project given it's name. The return value's CodeType.ProjectItem property will return a valid value (unlike EnvDTE.Project.CodeModel.CodeTypeFromFullName() which throws an exception).

Get the default namespace of the current project.

Get the filename to the current project.

Get all compiled assemblies referenced by the given project.

Get the currently selected projects from the EnvDTE.DTE object. The last known selected object is returned if no projects are selected.

This is a poorman's way to get the namespaces specified by using statements in the given project item. As well as using statements at the top of the file, it also includes the first defined namespace in the file.

Forcibly write the contents of a file to a project item.
