Oh, about getting a QDatabase from a Session, I just realized there is a much
easier way that doesn't require any code modification. The LINQ assembly adds
an extension method to the ordinary Database class that converts it to a
QDatabase. Just call session.Database.AsQueryable()

I created Visual Studio templates today for C# and VB custom action projects.
Look for them in the next build. I really should have done this before the
release -- sorry for making you figure things out the hard way.
I'm happy to review any samples you want to contribute or blog about.
Be careful with the LINQ stuff... as noted in the doc it is experimental and
has some limitations. I am interested in feedback about it though: How useful
do you think it would be if the implementation was high quality?
Anyway it looks there's currently no public way to get a QDatabase for a custom
action Session. That's an oversight that will be easy to fix. If you want to
get something working temporarily, you can change the internal QDatabase
constructor to public, rebuild, and then create one like this:
new QDatabase(session.Database.Handle, false, String.Empty,
DatabaseOpenMode.ReadOnly);
To query a custom table, just use the indexer on the QDatabase instance:
qdb[tableName] returns a general-purpose QTable<QRecord>. Or you can create
your own custom QRecord subclass (like the ones in Entities.cs) and create and
run queries on a QTable<YourCustomRecord>

If you'd give me some requirements and peer review my work, I'd be willing to
help contribute the samples as part of my DTF learning process.
BTW, I'm refactoring an ExecuteQuery/Scalar pattern I just wrote to LINQ and
I'm a little confused on how to get from session to QDatabase. the
db.InstallExecuteSequences explanation doesn't make sense to me. ( BTW, my
query is against a custom table, not a well known table ).

Yes, a VS project template for a managed custom action is something we've
talked about that would be nice to do. In general I want to work on some richer
CA samples in the coming months.

Sorry, one more question. How do you feel about WiX registering a new project
type in Visual Studio? A sample C# class that includes the right references
and plumbing to build the class and wrap it into a CA package assembly?

1) Yes, full support for the new functionality added in MSI 4.5 is near
the top of my list of things to work on in DTF. I have briefly looked at the
embedded external-UI feature, and I don't forsee any unusual technical
challenges to enabling embedded external-UI in managed code.
2) Oh, I guess that sample code in the doc is out of date. Properties are
accessed as an indexer directly on the session object. The CHM reference topic
for the Session class (Item Property) and the actual sample ManagedCA project
are correct.
3) DTF samples are included in the WiX sources (src/dtf/Samples) but not
in WiX3.msi.
4) Umm, grapefruit juice. Seriously. :)
Thank you for reporting these issues. I hope you find DTF useful.

I have a few other questions for you if you don't mind.
1) Will DTF have support for authoring MSI 4.5 style Embedded External UI
handlers?
2) The Sample C# custom action references a Session.Property[ string Property ]
but when I add the reference and using statement I get an error that that
Session doesn't have a definition for Property. Am I pulling in the wrong
reference or something?
3) The CHM topic references a Samples\ManagedCA directory. I don't see it?
4) What's your favorite beverage?

Looks like Errors.resources.resources got ignored by by the zip which is
supposed to pickup all the sources, because of the .resources file extension.
I'll fix it for the next build.
Meanwhile you can create that file by running resgen.exe on Errors.txt. (I
should probably make that happen during the project build anyway.) Or you can
build without it, but you'll get resource exceptions instead of error messages
if you encounter any errors in cabinet creation/extraction.

I also pulled the sources but I can't get the Compression.Cab project in the
DTF solution to build. It's missing the file Errors.resources.resources file.
If I exclude it from the project it seems to build fine though.
