Unable to cast object of type 'System.Reflection.RuntimeConstructorInfo' to type 'System.Reflection.MethodInfo'

I am using Dynamic LINQ in an ASP.NET MVC project to create queries at runtime.

First I create a string from client's request like this:

string predicate = GetPredicateString(request);

The predicate would have a value like "AvailableFrom = DateTime(2015, 10, 05)"

Then in my code I call ParseLambda method of DynamicLinq.DynamicExpression class like below.

var lambda = DynamicExpression.ParseLambda(typeof(Product), typeof(bool), predicate)

Doing so I receive the following exception:

Unable to cast object of type 'System.Reflection.RuntimeConstructorInfo' to type 'System.Reflection.MethodInfo'.

Line 1958: int FindBestMethod(IEnumerable<MethodBase> methods, Expression[] args, out MethodBase method){
Line 1959: MethodData[] applicable =
               methods
                   .Select(m => new MethodData
                   { 
                       MethodBase = m,
                       Parameters = m.GetParameters()
                           .Where(p => p.ParameterType != (MethodInfo)m).ReturnType).ToArray()
                   })
                   .Where(m => IsApplicable(m,args)).ToArray();

this part of the above fragment must be throwing the exception:

(MethodInfo)m)

I have tried to pass arguments matching other constructor overloads of DateTime structure, but it doesn't make any difference. So one can rule out passing invalid arguments being the cause.

I have to say that I am getting this exception only with DateTime and all other data types (string, int etc.) cause no problem.

I haven't found anything similar in the Internet, so I guess either I am doing something wrong or this is a very rare situation.

Any idea on how to resolve this issue would be greatly appreciated.
