I get this error:

Attempting to JIT compile method 'System.Linq.Enumerable: <FirstOrDefault> while running with --aot-only

The code has remained the same and it used to work perfectly. After one of the recent upgrades this error is occurring.

Here is an example of where it fails:

#region GetEmployees

public Employees GetEmployees(Employee employeeTemplate)
return this.Get<Employees>(this.Process, "GetEmployees", employeeTemplate);

And this never performs:

 protected B Get<B>(BusinessObject owner, string methodName, params object[] args)

return GetImpl<B>(XmlCompressionMethod.GZip, methodName,  ref args);


I am using the following trampoline settings:

-aot "nrgctx-trampolines=4048" -aot "nimt-trampolines=4048" -aot "ntrampolines=4048"

I have attached the Monotouch version screen
