This used to work in versions prior to 17.10. Might be related to dotnet/msbuild#11449

Version Used: 17.10.0-preview-24101-01+07fd5d51f

Steps to Reproduce:

This code compiles fine with dotnet build, but not msbuild

using System;
using System.Collections;


MyClass.CallFunctionWithIList([new Element()]);

public class MyClass
{
    public static void CallFunctionWithIList(ElementCollection list)
    {
    }
}

public class Element{}

public class ElementCollection : IEnumerable
{
    public IEnumerator GetEnumerator()
    {
        throw new NotImplementedException();
    }
    public void Add(Element element){}
}

Diagnostic Id: CS1503

Expected Behavior:

msbuild                                                                                                                                                                  pwsh   100  10:45:51 
