Hi, thanks for your script, saved me a lot of time.
However I've found that it doesn't work in case the Content element has children, like this for example :
<Content Include="Web.config">
<SubType>Designer</SubType>
</Content>

What I do then is simply change the if clause to match only self-closing Content elements like this :
if ($line -like '*<Content Include=*/>') {
Then I create a clean csproj file, then revert the test and run the report option and delete those manually (as there were not that many of them)

Lovely script; thank you so much!
One issue I have that PS is encoding the project file in Unicode, causing some unexpected errors for the (ASP.NET) compiler. Re-exporting it in UTF-8 worked. Commenting here for others who might run into the issue.
