VB -> C#: Async Function doesn't translate to async lambda

[brantburnett]

Input code

Return Await Me.ExecuteAuthenticatedAsync(Async Function()
    Return Await DoSomethingAsync()
End Function)

Erroneous output

return await this.ExecuteAuthenticatedAsync(() => {
    return await DoSomethingAsync();
});

Expected output

return await this.ExecuteAuthenticatedAsync(async () => {
    return await DoSomethingAsync();
});

Thanks for posting. The code around lambdas has a lot of cases, some are likely missing code like this

CodeConverter/CodeConverter/CSharp/LambdaConverter.cs

Line 111 in a5473fb

if (operation.Symbol.IsAsync) methodDecl = methodDecl.AddModifiers(SyntaxFactory.Token(SyntaxKind.AsyncKeyword));

So probably a few test cases needed but should be a straightforward change.
