IL2CPP

-

-

Priority: 3Not yet prioritized for a release

-

Severity: 2Core functionality majorly impacted

Steps to reproduce:
1. Download attached project
2. Build a "scene" for the Standalone platform
3. Launch player

Expected results: operation returns the correct value
Actual results: operation returns null

Reproduced with: 2019.1.0a8, 2018.3.0b9, 2018.2.16f1, 2018.1.9f2

LINQ operation (from SQLite client):
var tableAttr =
typeInfo.CustomAttributes
.Where(x => x.AttributeType == typeof(TableAttribute))
.Select(x => (TableAttribute)Orm.InflateAttribute(x))
.FirstOrDefault ();
Response avatar

Resolution Note:

We've corrected a problem was related to the AttributeType property of the CustomAttributeData type returned from TypeInfo.CustomAttributes. IL2CPP was providing the based class type (System.Attribute) instead of TableAttribute. The SQLLite code also uses the ConstructorArguments part of TypeInfo. Supporting this properly is difficult in IL2CPP now, as we will need to collect significantly more metadata and ship that metadata with the final build of a game. We're not planning to do that now, as it will increase distribution size too much.
