 - DLLs for msbuild tasks have to be build in `x64` because Visual Studio uses this architecture since VS2022.

+1. This flag disables "nodeReuse", this is needed as a custom MsBuildTask is used which also gets rebuilt. "NodeReuse" keeps instances of MsBuild running which interferes with the rebuilding of the custom MsBuildTask.
