NEST deprecated field [include]

I just updated elastic search from 2.3.4 to 5.0.1, and nest C# nuget package to the latest 2.4.7

I have the following nest query: 

        SourceFilter sourceFilter = new SourceFilter()
        {
            Include = Infer.Fields<Page>(p => p.Category, p => p.Title)
        };

        MultiMatchQuery multiMatchQuery = new MultiMatchQuery()
        {
            Fields = Infer.Fields<Page>(p => p.Title, p => p.MetaDescription, p => p.Keywords),
            Type = TextQueryType.PhrasePrefix,
            Query = search.Term
        };

        var searchQuery = new SearchRequest<Page>()
        {
            From = search.ResultsFrom,
            Size = search.ResultsSize,
            Source = sourceFilter,
            Query = multiMatchQuery
        };

        var searchResponse = client.Search<Page>(searchQuery);

I'm getting the following error back from elastic:

Deprecated field [include] used, expected [includes] instead

Commenting out the SourceFilter allows the query to run through.

Is there a different way to use SourceFilter ?

The syntax for Include should be Includes instead of Include according to source filtering usage. Even the error which you've mentioned above concise the incorrect syntax of Include. I ain't sure about the version compatibility though. If I reproduce yours, it should look something like this:

    Source  = new SourceFilter()
    {
      Includes = Infer.Fields<Page>(p => p.Category, p => p.Title)        
    };

If you're running against Elasticsearch 5.0.1, you should use a 5.x version of NEST; the latest 5.x version on nuget is 5.0.0-rc3 (a prerelease) at this time, with 5.0.0 to come out very soon.

5.x contains the Includes property on ISourceFilter that Kulasangar highlights in his answer.
