Cannot get type of implicitly typed array in VB.NET

Version Used: 1.2.2

Steps to Reproduce:

1. Have the following piece of code in your sample VB.NET solution (lets call {1, 2} initExpr):

   Dim a = {1, 2}
   

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,

3. 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.
