Tech Off - A question for WCF gurus

This is totally possible. Add the contract files to the client project as a link (Add | Existing Item | Add As Link). If you're willing to create the ChannelFactory on the client yourself then you don't need any config either.

Tech Off - WCF Contract first

myefforts2 — Tue, 02 Apr 2013 07:18:59 GMT

WCF can do this and is probably the best choice given your requirements.

See http://stackoverflow.com/questions/950150/how-to-use-a-wsdl-file-to-create-a-wcf-service-not-make-a-call for how to generate C# classes from the WSDL you have. That should give you a contract interface. To 'implement the contract' you create a service class implementing the generated interface and host that as a service.

You'll likely need to use BasicHttpBinding as a binding type.

Tech Off - WCF: The underlying secure session has faulted before the reliable session fully completed. The reliable session was faulted.

I would try adjusting the binding configuration (perhaps turning off reliable sessions) first to see if that eliminates or changes the error.

Alternatively, reducing the size of the message payload and using multiple calls might be the pragmatic solution.

Have you tried turning tracing on server-side to see if you get a better error? http://msdn.microsoft.com/en-us/library/ms733025.aspx

Tech Off - Windows Workflow Foundation 4.0 Scheduler

You could write a scheduled task that delivers a message to start your workflow service.

Tech Off - Dynamic MSSQL to Oracle query conversion

To answer your second question, I've not come across any such tool.

Tech Off - Dynamic MSSQL to Oracle query conversion

myefforts2 — Fri, 27 Apr 2012 19:32:16 GMT

I've seen some applications try to use a common subset of SQL that works across MSSQL and Oracle - they don't work out too good. (Plus you end up using none of the more advanced / non-standard features of either because the other can't support it.)

Unfortunately I think the best way to achieve what you're after is to write the queries again in PLSQL. How hard this will be will vary greatly depending on your number of queries and their complexity. I suspect this route will pay off over time, though and you'll end up with a more solid and/or performant solution.

Coffeehouse - Need help to build Expression Tree

myefforts2 — Wed, 25 Apr 2012 11:51:48 GMT

It looks like Expression.Property(...) is returning null. Are `variable` and `oFC.Field` correct?
