Parameters of lambdas in the supplied expression have lower priority than defined types, even when casing differs

[instantsc]

1. Description

727 is still not completely fixed in 1.3.5, contrary to the issue status. Parameters of lambdas in the expression still have lower priority than defined types, even when casing differs, e.g.

    [DynamicLinqType]
    public class X{     
    }

    public static void Main()
    {
        DynamicExpressionParser.ParseLambda<bool>(new ParsingConfig(), false, "new[]{1,2,3}.Any(x=>x>0)");
    }

This behavior should at least have a flag, preferably toggled on by default. Prefixing every single parameter with @ is a pretty involved workaround. Nevermind that doesn't even work. The only way out as far as I can see is just using a different name, which is less than ideal.

2. Exception

If you are seeing an exception, include the full exception details (message and stack trace).

Unhandled exception. '.' or '(' or string literal expected (at index 18)

Thanks, that seems to solve my issues.
