This view is perfectly valid in SQL Server, and can be created without a problem. In a Data Tools database solution, it prevents the solution from being built with a nonsensical error.

CREATE VIEW [dbo].[aview] with schemabinding
    id = try_convert(int, id)
from [dbo].atable d

Error    3    SQL70561: Cannot schema bind view '[dbo].[aview]' because name 'int' is invalid for schema binding. Names must be in two-part format and an object cannot reference itself.    C:\Users\...\Documents\Visual Studio 2010\Projects\...\Views\dbo.aview.sql    4    19    

It thinks the data type is an object. See attached screenshot, where "try_convert(int" is underlined in red.

Note that the project target platform is SQL 2012 and the project's database settings compatibility mode is SQL 2012.

Version of Data Tools I'm using:

In SQL Server 2012 Data Tools, Microsoft Visual Studio 2010
Version 10.0.40219.1 SP1Rel
Microsoft .NET Framework
Version 4.5.50709 SP1Rel
Installed Version: SSDS Standard
SQL Server Data Tools 10.3.21101.1
Visual Studio 2010 Shell (Integrated) - ENU Service Pack 1 (KB983509)

Also, the SQL Server Data Tools are up to date.
SQL Server Data Tools 10.3.21101.1
SQL Server Data Tools - Build Utilities 10.3.21101.1
Microsoft SQL Server 2012 Data-Tier App Framework 11.1.2820.0

I have the same problem with geography:

geography::STPointFromText('POINT(' + CONVERT(nvarchar(15), dbo.Audit.Longitude) + ' ' + CONVERT(nvarchar(15),
                         dbo.Audit.Latitude) + ' ' + CONVERT(nvarchar(10), dbo.Audit.Altitude) + ')', 4326) AS Location

In managemnet studio everything is working and view is created without single issue, however in VS 2012 I have error:
SQL70561: Cannot schema bind view '[dbo].[vAudit]' because name 'geography' is invalid for schema binding
