Error processing method: shareFileAsync during release buid - xamarin

Question

I'm having this problem in the compilation on Android.
When I use the method:
await Share.RequestAsync (new ShareFileRequest
{
Title = "Shared File:" + nameFile,
File = new ShareFile (fullPathFile)
});
I get this error
Mono.Linker.MarkException: Error processing method: 'System.Void WorkFlow2.Services.Utility/<shareFileAsync>d__8::MoveNext()' in assembly: 'WorkFlow2.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void Xamarin.Essentials.ShareRequestBase::set_Title(System.String)

This error returns at compile time for the release.
During the "debug" phase it works correctly.
