| Note that this must run before every invocation of CoreCompile to ensure that all compiler | |
| runs see the generated global usings. There is at least one scenario involving Xaml | |
| where CoreCompile is invoked without other potential hooks such as Compile or CoreBuild, | |
| etc., so we hook directly on to CoreCompile. Furthermore, we must run *after* | |
| PrepareForBuild to ensure that the intermediate directory has been created. | |
| Targets that generate Compile items are also expected to run before | |
| BeforeCompile targets (common targets convention). | |
