Deep Insights in Microsoft .NET

string invalidExtension = (from p in new List<string>  { ".dll", ".pdb", ".suo", ".docstates", ".ico", ".bmp", ".vs10x", ".vspscc", ".vssscc", ".vsp", ".scc", ".user", ".ctl", ".datasource", ".vsmdi", ".testsettings", ".trx", ".dat" }                             where p == files[i].Extension.ToLower()                            select p).FirstOrDefault(); if (string.IsNullOrEmpty(invalidExtension)) { //Means it has an invalid extension }

Nowadays, I am finding myself using Wolfram Alpha more and more especially in my work day because it can do some really intelligent things like finding the exact number of days between two days or the number of seconds between 2 times. http://www.wolframalpha.com/ This can be really useful!

When my laptop only had 4GB RAM, the process was consuming upto 512MB RAM and also being very slow. Now, when RAM is 8GB, it is fast, but consumes around 155MB RAM. Interesting... Win 2008 r2 x64

http://www.websofia.com/2011/03/get-local-machines-mac-address-in-c/ I have used a similar technique to iterate through all the network info for the local machine.

To stop a windows service: net stop <service name> To kill a process: taskkill /im "<exe name>" To kill a remote process: taskkill /s <server name> /u "<domain>\<user>" /p "<password>" /im "<exe name>" Change Directory: cd "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\" Build a Visual Studio Solution: devenv %devdir%<solution file name> /build Debug Build a solution using MSBUILD: msbuild %devdir%<solution name> /property:WarningLevel=0 /p:Configuration=Debug Copying files to another folder: xcopy %devdir%<project folder>\bin\Debug\*.dll "C:\Program Files (x86)\<folder>\" /y /s /q Starting a Windows Service: net start <service name> Showing "press enter to exit": pause

Found a few references: http://stackoverflow.com/questions/2394084/wcf-the-user-specified-maximum-retry-count-for-a-particular-message-has-been-exc http://consultingblogs.emc.com/pauloreichert/archive/2007/12/14/6081.aspx#9331 http://social.msdn.microsoft.com/Forums/en/wcf/thread/555b47a1-158a-4a42-9b73-d748a4e83b15 http://www.smartasses.be/2009/01/26/wcf-reliable-session-and-keep-alives/ Interesting because I have implemented keep alives for duplex communication earlier. In this case, I tried doing this: <reliableSession inactivityTimeout="23:00:00" maxRetryCount="8192"             ordered="true" />

It is fairly easy to do this - while creating the website, specify a different host name. In a dev environment, you can point this host name to 127.0.0.1 in the windows hosts file. Interestingly the mac also has a hosts file which looks similar to the windows hosts file.

This seems to be new behavior in .NET 4.0. I found a solution for it, below: http://social.msdn.microsoft.com/Forums/en/vssetup/thread/5a8d1501-1adb-4010-b6d2-c70d69b905f8 In the end, I changed the color of the label to get the effect I wanted.
