问题
I'm writing an extension which adds files to projects in the solution.
It makes sense to check first for unsaved changes and if there are any, ask user to save.
How can I achieve this?
Are there any open source VS extensions which do this so I can take a look how it's done?
回答1:
To find out if there are unsaved changes, you can enumerate open documents with DTE.Documents and check each one for the Document.Saved property.

You can try to work with project via Microsoft.Build.Evaluation that has corresponding functional.
Extension which adds files to projects in the solution.
After including new files to the project, they must be reevaluated. Pay your attention on Project.IsDirty property:
A project is modified and must be reevaluated when the underlying project source code, including changes to imported files. A project is also modified must be reevaluated if the project tool set changes.
Project.IsDirty | Project.ReevaluateIfNecessary | Project.Save
