Repro Steps

1. Have a Wix v3 wixproj with a wxs with a Component with a File with an @Id attribute only:

<Component>
	<File Id="MyFile.dll" />
</Component>

2. Notice that it builds/compiles fine. The file name is taken from the id.
3. Run wix convert (using FireGiant HeatWave Community Edition)
4. Notice that the conversion succeeded with no errors
5. Try to build the wixproj

Actual Result

The component has not been converted, it is the same as before conversion:

<Component>
	<File Id="MyFile.dll" />
</Component>

But the compiler spits out an error:
error WIX0010: The File/@Name attribute was not found; it is required.

Expected Result

Either: like in v3, the @Name attribute is not required and defaults to value of @Id:

default value is ... the value of the Id attribute, if the Source attribute is omitted or doesn't contain a file name.

Or, if that v3 rule will never be valid anymore: the wix convert process should add an @Name attribute and remove @Id.
