Visual Studio 2010 with ASP.NET MVC1.0
Is it possible to use Visual Studio 2010 to write code for shared hosting that is designed for .NET 3.5 and ASP.NET MVC 1.0? I've been trying for a while to get a project to run that uses only 1.0 features, and it just will not translate over very well. ...
Should folder names start with a period?

Is there a way to enable the IE8 Developer Tools from inside WebBrowser control in a .NET application
If you have IE8, you may have noticed a really handy feature that MS has added. Hit F12 and Developer Tools, a firebug like debugger, pops up. This is extremely useful for debugging purposes, and i'm wondering if there is a way to pop up the Developer Tools from a WebBrowser control inside a .NET application. My situation is this: I hav...
Building a worker thread pool for a non-thread-safe code
What's the best way to wrap non-thread-safe code in the .net framework? I've got a third-party library that isn't thread safe due to its use of static variables. Rewriting it isn't an option. This library is used by an asp.net web service that receives lots of simultaneous calls. I've currently got it wrapped in a proxy class that uses...
FlowDocument contents as text
What is the best way to get back the XAML/XML value of a FlowDocument? I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc...

Can I force my own short-circuiting in a method call?
Suppose I want to check a bunch of objects to make sure none is null: if (obj != null && obj.Parameters != null && obj.Parameters.UserSettings != null) { // do something with obj.Parameters.UserSettings } It is an alluring prospect to write a helper function to accept a variable number of arguments and simplify this kind ...

I am having a slight issue with the HttpWebRequest protocol, and I am wondering whether I should try a different approach or perhaps I am doing something wrong. The issue I am having is this.

Adding collected errors to database
I have an application that monitors a process and "learns" exceptions, by adding them to a DB. The process to gather the errors/exceptions is pretty solid, but not the storing on the DB side. What I want to accomplish is something like public int GetErrorId(string StringToClassify) { sql = "SELECT [id] FROM [DBNAME].[dbo].[ERRORS] WHER...

In the app I'm working on, I need to maintain a list of Projects which are currently loaded, and display the names of each one in a ListBox (okay, multiple ListBoxes, but that's neither here nor there). class Project { public String Name; // Etc. etc... } I've got a BindingList object which contains all of the loaded Projects...
Where to place Business Entities, Enums, Custom exceptions?
I'm trying to figure out how to share my entities between the data, business, and UI tiers. Is it best to create a separate project for these entities that will be referenced by all the tiers?

NHibernate parent mapping does not create child foreign-key
Hello, I am just learning NHibernate. I have been using examples from the documentation and here at stackoverflow, but I must be missing something. I have a PARENT object that has a collection of CHILD. A CHILD is meaningless without a PARENT, so the database has FK set to NOT NULL. Implementing NHibernate from CHILD to PARENT works f...

C# Child Process from Legacy C++ App Windowing Problems...
We have a c++ legacy application and have been extending it with c# applets that are invoked using COM from the parent c++ app. They bring up windows that are not modal. Moreover, I think these .NET windows are not proper children of the c++ application, since EnumChildWindows misses them, and EnumWindows finds them. One child-like beh...
