You have to implement=C2=A0IComputeFunc.

Ignite.NET do= es not have overloads for anonymous functions & lambdas.

We h= ave plans to add them in future versions.

In Java I can do the following:

List<String> listOfWords =3D Arrays.asList("How many characters = are
there?".split(" "));
Collection<Integer> res =3D ignite.compute().apply((String word) ->= ;
word.length(), listOfWords);
----
Now I'm trying to do the same in .NET with C#:

ICollection<string> words =3D "Count characters using
closure".Split().ToList();
var res =3D ignite.GetCompute().Apply<string, int>((string x) = =3D> x.Length,
words);
----
It looks like it is trying to invoke the following method:
TRes Apply<TArg, TRes>(IComputeFunc<TArg, TRes> clo, TArg arg);=

Instead I want it to invoke the following method:
ICollection<TRes> Apply<TArg, TRes>(IComputeFunc<TArg, TRes&= gt; clo,
IEnumerable<TArg> args);

Both apply overloaded method have the same amount of paramters, so how do I=
specify it to use the correct apply method? I don't want to create an implementation of the IComputeFunction but want to use lambda like I can do=
in Java.

I have tried different combination of the <> after Apply, for example=
Apply<string, int> or without the <>.
The complete code (using implementation of the IComputeFunction) is in the<= br> .NET examples of ignite. I'm trying to find out the equivalent lambda w= ay in
C#.
