Get Popup ... Please enable Deploy in Configuration Manager ... when it is enabled

[ScottAlexanderOpto]

Describe the bug

I added this: None
to my csproj in a base template package. When I do that, it gives me a popup message that I need to enable Deploy. I've looked throughout the application for other places to set Deploy. And I get this error: DEP1560: Failed to read manifest file "C:\Users\ScottAlexander\src\repos\LasSystem\TEST_TEST\bin\x64\Debug\net8.0-windows10.0.19041.0\win-x64\AppxManifest.xml". It may need to be regenerated. Try running the Rebuild Solution command to fix the error. FileNotFoundException - Could not find file 'C:\Users\ScottAlexander\src\repos\LasSystem\TEST_TEST\bin\x64\Debug\net8.0-windows10.0.19041.0\win-x64\AppxManifest.xml'. [0x80070002] - C:\Users\ScottAlexander\src\repos\LasSystem\TEST_TEST\bin\x64\Debug\net8.0-windows10.0.19041.0\win-x64\AppxManifest.xml

Steps to reproduce the bug

1. Create a new WinUI3 application (first one on list)
2. Add None
3. Rebuild
4. Start Debugging

Expected behavior

I expect it to do as the app https://learn.microsoft.com/en-us/windows/apps/winui/winui3/create-your-first-winui3-app says. Instead it doesn't work at all. I'm doing this because that is how I got the Media sample to run (from another answer).
