Entity SQL IN/Multiset issue

Question

I am using the following query in entity sql

Select n.Name as NodeNameN from Nodes as n where n.Name IN MultiSet (@Test) 
: 

The value is substitued at runtime using the below code 

var reader = model.CreateQuery<System.Data.Common.DbDataRecord>(                 Statement,                 Parameters.ToArray()); 

When this is executed, the corresponding statment generated in sql server is as below :

exec sp_executesql N'SELECT  1 AS [C1],  [Extent1].[Name] AS [Name] FROM [dbo].[Nodes] AS [Extent1] WHERE [Extent1].[Name] = @Test',N'@Test nvarchar(4000)',@Test=N'''BMA'',''Area A'','

Instead of "IN" Clause the "=" clause is substituted.

Am I doing any thing wrong here.
