Rebuild causes build errors in Visual Studio 2020 Preview 4 and Visual Studio 2019

[JohnBergman]

Which exact Umbraco version are you using? For example: 8.13.1 - don't just write v8

9.0.0

Bug summary

Brand new project created using the visual studio 2020 File-New method.

close, reopen visual studio, then do a rebuild all with multiple projects of multiple types (in my case I have a database project, a couple of class libraries that are .net 5, and the umbraco project.

Right-clicking on the solution and choosing rebuild leaves a bunch of build errors, as seen in the imag

es

If I right click on the project itself and select build or rebuild it is fine.

Specifics

No response

Steps to reproduce

Expected result / actual result

Regardless of how I choose the build/rebuild, the results should be consistent.

Can confirm this happens in Visual Studio 2019 as well as 2022 Preview 4, could you update the issue title @JohnBergman?

Issue seems to be the BeforeTargets value specified on the CopyUmbracoAssets target here, which is leading to the target being skipped when running a Rebuild rather than just a Build

https://github.com/umbraco/Umbraco-CMS/blob/release-9.0.0/build/NuSpecs/build/Umbraco.Cms.StaticAssets.targets

BeforeTargets="Rebuild;Build" rather than just BeforeTargets="Build" may fix this

Replicated on a fresh 9.0.0 project
