• Where has XamlPad gone in .NET 4.0 / Windows SDK v7.1 / Visual Studio 2010?

  - by elck03

  I can't find XamlPad anywhere after I installed .NET 4.0 / Visual Studio 2010 and Windows 7 SDK - v7.1. I tried searching C:\Program Files\Microsoft SDKs\Windows\v7.1\bin and did a dir /s xamlpad.exe to see if the Windows Index service didn't get to that folder yet. And it's not under Start Menu - All Programs - Windows SDK v7.1 -- Tools. Where has it gone? Did MS deprecate it? Thanks

• How can I sort just part of a list using vb .net?

  - by Eyal

  In VB .Net, the Generics Lists have a sort function that accepts IComparer or Comparison. I'd like to sort just part of list. Hopefully I can specify the start index, count of elements to sort, and a lambda function. It looks like you can only use lambda functions to do this if you're sorting the entire list. Is that right or did I miss something?

• When creating an bitmap image from scratch in VB.Net, the quality stinks?

  - by ajl

  The Vb.Net application creates a bitmap from scratch and either converts to a tiff or sends it to a printer. In both cases, the quality of the image (in this case the font) is not good at all. The sample code listed below creates the graphics object that I use to write to the image. Dim gr2 As Graphics = Graphics.FromImage(New Bitmap(800, 1000), Imaging.PixelFormat.Format32bppPArgb))

• Is there a way to tell .NET where to look for the user settings file?

  - by Davy8

  Basically multiple instances of our application will be launched but they need to have separate user settings. We currently have use "user settings" for that, and it works fine for a single instance (per windows user) but we would like to be able to launch multiple instances with say a settings path passed in via command line. Is there a way to do this with the built-in .NET settings or will we have to roll our own?

• How do you specify a direct build name directory using TFS build of an ASP.net web application?

  - by Mark Kadlec

  I have a TFS build set up to deploy an ASP.net project to a test server. The build works great, and deploys to the test server fine, but instead of putting it into the \Website directory that my IIS webserver is configured for, it puts the build into \Website_20100511.6 Why is the date suffixed to the directory name? Is there a way to turn that off so I can publish directly to the \Website?

• Which View Engine are you using with ASP.NET MVC?, and Why?

  - by Sosh

  Hi, I'm thinking of experimenting with alternative View Engines for ASP.NET MVC, and would like to know what other people are using. Please let me know 1) Which View Engine you use, and 2) Why. The standard 'web-forms' view engine is of course a valid answer, but please say so only if you have decided to use it for a reason, not just 'Becuase I can't be bothered to change it' ;) Thank you!

• Can you point me to current examples using NHibernate in an ASP.NET MVC2 app?

  - by alphadogg

  Can anyone point me to any self-contained, complete, current reference materials/projects using NHibernate in an ASP.NET MVC2 application? I have looked at Sharp Architecture, but I am not sure I need the complexity in that project. I certainly don't know enough about it to know if it is over-engineered for my purposes. I would like to see more types of implementations to gauge the various ways people have skinned this cat.

• How can CruiseControl.Net fail a build based on changing metrics?

  - by skolima

  I would like CruiseControl.Net to fail a build when some code metrics change in a 'wrong' direction, i.e. code coverage decreases or Gendarme defect count increases. The Gendarme metrics are already tracked in report.xml file (because they are presented on web dashboard graphs), the code coverage is only reported on build status page (and saved in build report xml). How can I achieve this?

• Is .NET a write once, run anywhere (WORA) platform like Java claims to be?

  - by Scott Saad

  I remember Sun's slogan so vividly... "Write Once, Run Anywhere". The idea being that since programs are compiled into standard byte codes, any device with a Java Virtual Machine could run it. Over the years, Java seems to have made it onto many platforms/devices. Is this the intention or was it ever the intention of .NET. If so, what kind of efforts are being put forth to make this a reality?
