ParseException after update from v.1.0.8.18 to 1.0.9.0 or any newer (till 1.3.7)

[OlegNadymov]

1. Description

I have string expressions with inner string statements, e.g.:

StaticHelper.First(StaticHelper.SubSelect("Identity", "AdditionalProcessState", "Code = ""New"" ", ""))

The class:

public static class StaticHelper
{
    public static Guid? GetGuid(string name)
    {
        return Guid.NewGuid();
    }
    public static SqlExpression SubSelect(string columnName, string objectClassName, string filter, string order)
    {
        return new SqlExpression();
    }

    public static object First(SqlExpression sqlExpression)
    {
        return Guid.NewGuid().ToString();
    }
}

public class SqlExpression
{
}

This class is already used in TestCustomTypeProvider of your test class DynamicExpressionParserTests.

I try to parse the expression this way:

var exp = @"StaticHelper.First(StaticHelper.SubSelect(""Identity"", ""AdditionalProcessState"", ""Code = """"New"""" "", ""Order""))";
var lambda = DynamicExpressionParser.ParseLambda(config, typeof(User), null, exp);

3. Fiddle or Project

I have done changes in DynamicExpressionParserTests adding SqlExpression, StaticHelper.SubSelect, StaticHelper.First locally only to check the first version where I can't parse my expressions. I have not done any PR.

4. Any further technical details

It is working on v.1.0.8.18. But it is not working on versions since 1.0.9.0 till the latest 1.3.7.

I want to upgrade to the latest version because of:

Warning As Error: Package 'System.Linq.Dynamic.Core' 1.0.8.18 has a known critical severity vulnerability, https://github.com/advisories/GHSA-w65q-jcmv-28gj

@OlegNadymov It should be fixed.

please try preview NuGet from https://www.myget.org/F/system-linq-dynamic-core/api/v3/index.json

@StefH thank you! I'll be able to check tomorrow. I'll let you know.

@StefH I've done several tests. Everything is Ok! 👍 When are you going to release this fix?

[StefH]

I cannot give an indication when this will be released, for now use that preview version.

[OlegNadymov]

Ok. Thank you!

@StefH I did more tests. Unfortunately, the new version still does not work with more complex expressions. I'll make a new issue with the demo. Here: https://github.com/zzzprojects/System.Linq.Dynamic.Core/issues/759
