@jonathanpeppers I repeated your test setup with a Here is the overview of the expected behaviour and property values (verified by inspecting binlogs and order of evaluation): Case: TrimMode=full, debug
Case: TrimMode=full, release
SuppressTrimAnalysisWarnings=false, debug
SuppressTrimAnalysisWarnings=false, release
IsAotCompatible=true, debug
IsAotCompatible=true, release
ConclusionThe added test in this PR does not seem to have correct expected values, please take a look at my notes above, and let me know if you have any questions. More importantly, the good news is, that the change in |

One change we need in the Android workload is to make sure that
trimmer warnings are displayed if a project sets `$(IsAotCompatible)`.
Customers would likely want this set for all platforms if they are
using NativeAOT on iOS or MacCatalyst.
I also wrote a test with somewhat complicated parameters to verify
we get warnings.
First, I can create a warning for both `IL2055` and `IL3050`:
// Member field
Type type = typeof (List<>);
// ...
// Later in OnCreate
Console.WriteLine (type.MakeGenericType (typeof (object)));
The combinations of tests are:
| Configuration | Property | Warning(s) |
| ------------- | ---------------------------------- | ----------------- |
| Debug | (defaults) | None |
| Release | (defaults) | None |
| Debug | TrimMode=full | None |
| Release | TrimMode=full | IL2055(2) |
| Release | SuppressTrimAnalysisWarnings=false | IL2055(2) |
| Debug | IsAotCompatible=true | IL2055, IL3050 |
| Release | IsAotCompatible=false | IL2055(2), IL3050 |
Some of the cases receive duplicate warnings, but this is expected as
the same behavior occurs in the simplest case:
* `dotnet new console`
* Add the above code to `Program.cs`
* `dotnet publish -c Release -r win-x64 -p:PublishAot=true`
* Receive warnings from both the Roslyn analyzer and ILC (NativeAOT compiler)
In a future PR, I might try to "fix" the duplicate warnings.
