Windows Phone 7
boomerbubba
reporting about Microsoft's rollout of the Windows Phone 7 OS to
developers. From what I can tell, it will not be possible to run
SQLite on that platform. The initial release will offer developers no
SQL engine for a persistent data store, and a future release is
expected to expose an embedded instance of SQL Server Compact Edition
(CE).
So LDSql as now consituted could not be implemented on this platform.
Theoretically it would be possible to port the schema to the MS SQL
Server CE dialect of SQL (or the dialects for MS Access, MySQL,
Oracle, etc.) But there is not now any plan for that.
Windows Phone 7 does not allow any native-code apps so I don't think a
third-party instance of the SQLite engine could be installed there, as
it can on the Windows Mobile platform. BTW, the legacy Windows Mobile
OS is being rebranded as Windows Phone Classic, and is expected to
coexist for some time. Personally, I have doubts about its long-term
viability.

platform they would break compatibility between every release. They
didn't do much much to it from 2003 until now and compatibility was
fine. Now they start working on it again and once again they are
breaking compatibility.

I viewed that video. Thanks for the link. I believe the presenter
can only have been referring to C#-SQLite, which is an unofficial and
somewhat experimental port of the SQLite C source into C#. And the
context of the Q&A was not about the Windows Phone 7 implementation of
Silverlight 3, but about Silverlight 4 in .NET. Perhaps that would
work on the phone, but I'm not sure. So perhaps that is a partiaI
solution for those who want to build such an engine from scratch. It
is pretty clear that native SQLite and its wrappers cannot be run on
the phone.
Meanwhile, this presenter seemed to contradict other speculation I had
seen about future support for SQL Server Compact Edition. At this
point, unlike the other major smartphone platforms that have SQLite
baked into the cake, WIndows Phone 7 does not have any embedded SQL
engine at all. Developers are reduced to finding ways to build their
own in some way that will not violate the security framework.

.Net wrapper out there.
Yes Silverlight 4 is how to break the bounds, but it does seem like this OS
is just the Zune OS as a phone, not sure why they did not call it Zune Phone
or something. XNA was available for Zune prior, but is also how developers
can write games for the Xbox.
There are obviously a lot more videos and more to learn about this OS, but
not looking promising for my existing application we sell as we need native
hooks and they don't seem to be exposed thus far.
I do think we could pull it off for this version, but will require more work
as things they have built in for other platforms are not there in this
Express Edition. I need to fire up my virtual machine where I have the full
VS2010 Ultimate installed.
Will keep you posted.
Andy,

going to spend more time on it. I found a new rewrite of C# SQLite that is
pure .net code and some features are removed to make it work,
http://www.itwriting.com/blog/1695-proof-of-concept-c-sqlite-running-in-silv
erlight.html. There is a lack of other base classes available, like
System.Data, so I will agree with you for now Ross Windows Phone 7 (to me
Zune Phone) will not be a candidate for Ward Tools for now.
