Distributing WPF apps to a legacy user base: How seamless is it?

I'm considering developing a WPF application, to be hosted by a legacy Windows app (C++), and I'm trying to get a better sense of how feasible it'll be to do so, given the broad user base I'm targeting.

Log off user from Win XP programmatically in C#

How would you disable .net Winforms Controls without changing their appearance ?

Let's say I've got a control and I want to prevent it from being edited. Setting the Enabled property of the control to False will work but the control appearance will change accordingly, usually to a difficult to read black over gray font.

MVC: Multiple submit forms in one form tag

I'm just starting to play with MVC, and something isn't clicking with me. I understand how to make a simple input form, and use a submit button to post the form set up like this: <form runat="server" method="post" action="/Home/CreateNew" > But what happens if you're whole app is inside one form tag, and you want to have multiple inpu...

Enitity Framework with long-running object context

One of my chief annoyances with Linq to SQL in WinForms (and I daresay WPF) is the lack of support for long running datacontexts see here. The problem is that you can't get updates from the database, you only ever get the same old records until you throw the datacontext away. This is fine for a web app when the page is only alive for m...

Goal I would like to be able to both host and connect to a vanilla sockets server via WCF, within the hosting framework I am devising.

MSTest.exe not finding app.config

I'm currently trying to run MSTest.exe from NCover, but I believe the question could apply generally to running MSTest.exe from the command line. If I have the "/noisolation" argument, then MSTest.exe appears to find and use the app.config as expected. Without it, NCover doesn't capture any coverage information. From my research so fa...
