Question

How is

<None Include="C:\foo.bar" />

different from

<Content Include="C:\foo.bar" />

?

Thanks

Answer 1

One difference is how they get published; "None" items don't get included in a publish, "Content" items do; for example, on the "Application Files" dialog on the Publish tab.

Answer 2

The MSDN article on the build action property explains the differences.

None - The file is not included in the project output group and is not compiled in the build process. An example is a text file that contains documentation, such as a Readme file.

Content - The file is not compiled, but is included in the Content output group. For example, this setting is the default value for an .htm or other kind of Web file.
