We are running into a similar issue. We get the same error when declaring a read-only property without a setter. We found a workaround that if you add a setter to the property it works fine.

Model config:

 entitySetConfig.EntityType.Property(p => p.Category)
		.HasComputed()
		.IsComputed(true);

This throws an exception at startup in the model builder:

public CategoryEnum Category
{
  get  { .... logic... }
}

but if we do this as a workaround it works fine.

public CategoryEnum Category
{
  get  { .... logic... }
  set  { throw new NotSupportedException(); }
}
