Note first: I'm trying this with mono 4-8-0-branch so master may not have this problem.

The attached source fails to build with mcs, due to:

    /home/atsushi/Desktop/PortableTest/Test.cs(68,68): Error CS0121: The call is ambiguous between the following methods or properties: `LambdicSql.Symbol.From<decimal>(this LambdicSql.Clause<decimal>, params object[])' and `LambdicSql.Symbol.From<decimal>(this LambdicSql.Clause<decimal>, params object[])' (CS0121) (PortableTest)

(The source in the sample is not very informative, it depends on NuGet package that has the mentioned methods.)

The source repo for the nuget package: https://github.com/Codeer-Software/LambdicSql

Already fixed in mono 2017-02
