MSBuild 14.0 Linq Expression Compatibility Issues

[yousefcodes]

Hi,

When using Visual Studio 2015 or MSBuild14.0, the compiler has an issue casting LINQ expressions. While attempting to translate a LINQ Expression to ZOQL, I get this error:

Unable to cast object of type 'System.Linq.Expressions.FieldExpression' to type 'System.Linq.Expressions.ConstantExpression'

This only happens with an expression that consists of two or more conditions, such as:
_zuoraClient.QuerySingle<ZuoraInvoice>( i => i.InvoiceNumber == number && i.CustomerId == account.AccountId);

It does not happen with:
_zuoraClient.QuerySingle<ZuoraInvoice>( i => i.InvoiceNumber == number);
