…ps and/or compute their run arguments we include default items This is load-bearing for some project types, so we instead just make sure that restore-only pathways keep the old default-item exclude

Consider adding some tests that would reproduce the issue which this is fixing.

I will probably add a test upstream in dotnet/android, I don't know how you'd reproduce the problem without the Android workload:

I think it should be fairly easy to repro in dotnet/sdk by adding <CallTarget Targets="Build" /> or something similar in a custom target that runs before/after ComputeRunArguments.

I want to get this in for RC2 and hopefully not wrestle with CI failures more than necessary, so I'll log a follow-up issue to create a test case to pin the behavior. |

Potential fix for dotnet/android#10500.
Historically we've included
EnableDefaultItems=falsein purely-evaluation or Restore scenarios as a free performance bump, since doing MSBuild glob expansion is a performance hit that isn't generally necessary in those cases.However, we were including this flag even when running run-related Targets that in android's case involve actual building, so this assumption no longer holds. Due to this, we remove the optimization.
