Has anyone tried deploying unsafe code in Azure? I'm working with code containing unsafe blocks dealing with pointers and all that fun stuff. And I'm wondering if that has something to do with errors I'm getting trying to deploy/upgrade the web project in Azure. Also, is there actually a way to view specific errors that are breaking...
I am developing a WPF kiosk like client that will be deployed on an HP TouchSmart Windows 7 machine with multi-touch enabled. My problem is that with Windows 7 multi-touch, the application does not recognize a finger 'tap' as a button press event, and therefore the button press Trigger to change color is never fired. The Windows 7 an...
I'm using a number of ObjectListView controls on a form in my current project. Today I migrated the project from Visual Studio 2008 to Visual Studio 2010. Now when the form is displayed all the OLV controls look as if they are disabled yet they are not. I have no problem scrolling the lists, or selecting items in the list. In addition, t...
I am using wsdl.exe to convert a WSDL file and Types.xsd file into a C# file. The wsdl file specifies optional variables (minOccurs="0" maxOccurs="1"), and the generated .NET type handles this by created two fields - one for the variable (e.g. status) and one to let you know if it's specified (statusSpecified). Is there a way to use the...
I need to open a file but if it's currently not available I need to wait until it's ready. What's the best approach to take? SCENARIO I'm using files as a persistent caching mechanism for application data. This data needs to be read and deserialized often (written only once, and deleted occasionally). I have a cleanup process that runs...

I am looking for a good tutorial / explanation that shows where and how to implement settings in a MVVM WPF application. I understand .net has built-in support for settings but is this typically used for medium to larger size applications? What are the alternatives? I am thinking of storing many user settings such as window size, grid...
This is a problem I used to have all the time with the serial port class in .NET 2.0. It was suggested that upgrading to .NET 4 would fix the problem... and it did in almost all cases. If I am using the serial port class built-in to .NET to communicate with a USB-to-serial adapter, and the adapter is unexpectedly unplugged while the po...
1) In a standard .Net application, are classes loaded as they are required? (e.g. If I have a class with a static constructor, is that static constructor only run the first time that class is needed?) 2) In an ASP.Net MVC (or web forms) application, is the static constructor invoked on every request that uses it? Or is it only for the f...

First off, we want to be able to have multiple people in one conversation and multiple conversations going on at the same time. After doing some research, a lot of people suggested long-polling. Scalability sounds like a problem thoug...
According to the documentation on the ConditionalAttribute class: Applying ConditionalAttribute to a method indicates to compilers that a call to the method should not be compiled into Microsoft intermediate language (MSIL) unless the conditional compilation symbol that is associated with ConditionalAttribute is defined. ...
I'm drawing a blank here; I can't find it, unless I'm really overlooking something under my nose. I'm trying to store a list of ints in a data structure. But after I add them, I will later in code check if an int exists in the list already. The generic List<int> does an O(n) operation with its Contains(). I want something that works ...
can any on explain me what are state machines in .net ...

I'm finding myself in need of "combining" several instances of the same type. This type has several IList properties on it. I want to take each instance and combine the values of those IList properties across the instances, so my code only needs one of those instances. I'm thinking of creating an ICombinable interface, but I'm wonder if...
