Steps to Reproduce:

Have the following piece of code in your sample VB.NET solution (lets call {1, 2} initExpr):
```
Dim a = {1, 2}
```
setup roslyn code analysis solution and try to get type of initExpr syntax node using:
```
var type = model.GetTypeInfo(initExpr).Type
```
where model is SemanticModel of document where initExpr resides,
observe type is null

Expected Behavior: Type of initExpr should be Integer()

Actual Behavior: Type of initExpr is null

Why?

above approach to get type info works just fine in C# for implicitly typed arrays such as new[] {1, 2},
putting cursor over a variable a in Visual Studio correctly shows it is of type Integer() so the type is obviously known and should be returned when trying to access it via GetSymbolInfo method.

Issue initially described at StackOverflow.

Direction de recherche: Inspectez le traitement des expressions d'initialisation de tableau VB.NET dans le modèle sémantique et comparez le avec les expressions de collection C#. Cherchez où GetTypeInfo retourne null et tracez le chemin de résolution de type.
