Hi,
take look at https://www.arangodb.com/docs/stable/analyzers.html#text
and
https://www.arangodb.com/docs/stable/analyzers.html#ngram

the EdgeNgram property is for text analyzers only (yeah i know it's quite confusing)
for ngram align the min, max, preserve props

await Arango.Analyzer.CreateAsync("test", new ArangoAnalyzer
  {
      Name = "text_fr_ngram",
      Features = new List<string> { "frequency", "norm", "position" },
      Type = ArangoAnalyzerType.Ngram,
      Properties = new ArangoAnalyzerProperties
      {
          Min = 3,
          Max = 26,
          PreserveOriginal = true,
          Locale = "fr.utf-8", // NOPE - not for ngram
          Case = ArangoAnalyzerCase.Lower, // NOPE
          Accent = false, // NOPE
          Stopwords = new List<string>() { "le", "la", "les", "de", "des", "du" }, // NOPE
          Stemming = false // NOPE
      }
  });

However since you want to use stopwords, then you might want to switch to text analyzer
As you did on arangosh

await Arango.Analyzer.CreateAsync("test", new ArangoAnalyzer
{
    Name = "text_fr_ngram",
    Features = new List<string> { "frequency", "norm", "position" },
    Type = ArangoAnalyzerType.Text,
    Properties = new ArangoAnalyzerProperties
    {
        EdgeNgram = new ArangoEdgeNgram
        {
            
            Min = 3,
            Max = 26,
            PreserveOriginal = true,
        },
        Locale = "fr.utf-8",
        Case = ArangoAnalyzerCase.Lower,
        Accent = false,
        Stopwords = new List<string>() { "le", "la", "les", "de", "des", "du" },
        Stemming = false
    }
});

It's partly my fault for merging all options into a single props object,
but it saves so many permutations.

its documented on the props however
