I was given this solution to a problem I had, since I didn\'t know how to integrate MS Word with C#: http://www.dotnetperls.com/word
I looked into this solution, and
You may also use NuGet Package Manager in order to install the reference. Go to Project -> Manage NuGet Packages... Search for "Interop.Word" and install that package.
Good thing about it is that you don't need to think about where the dll is located. When another person will check out the solution, NuGet will get all needed packages onto their machine.
