ASP.NET Development Server always needed a restart

Problem

I work in VS 2008, and every time I made a change to my code / html I had to stop the ASP.NET development server – apparently called Cassini.

This was a little irritating as you can imagine, after scouring the internet every time I had a chance for a few months, I was ready to give up, I even posted on a few forums.

Then I found a great site that spoke about nothing to do with the server, and guess what it is working. It has to do with how .net is dealt with on you machine, and it obviously assumes you are not a coder by default.

The Fix

On the MSDN forums I found a reference to the Microsoft knowledge base: KB911272. In summary

Essentially the HKLM\Software\Microsoft\ASP.NET\FCNMode determines how ASP.NET is dealt with as an app on the box.

Initially setting this to "0" fixed the problem, but this caused a UNC share problem, so then I set it to two after finding this great item

hosting-on-a-unc-share-is-not-supported-for-the-windows-xp-platform.aspx

And now I can change my code and run on the fly.

I'm having this exact same problem with VS2008. I just recently installed VS2010 and continue to have it, unbelievable! I've tried this FCNMode setting at 0 and 2, neither make a difference. This is such an incredibly frustrating problem -- can you think of anything that could help me? I'm running .NET 2.0.50727.4927 and 4.0.30319.1 on Win7 64-bit.

I'm starting to think the 64-bit is the problem, but I can't be the only one in the world with VS2008/2010 on Win7 64bit. Ugh!

Thanks for letting me vent.

You have to do a reboot between, have had the problem a number of times since this post and it has worked every time. Otherwise the ASP.NET forums have been remarkably helpful for me. Thanks for taking the tim eto comment

Bitcoin / Cryptocurrency – what is it and how can I benefit

What is it I started investigating Bitcoin when it was worth just over $1000 a bitcoin. I was interested in what it was and how it worked. A lot of people are saying we missed the boat, but I believe that everyone should at least try put a little money in now, or at least use a faucet (see below) to make a little micro-currency. You can read a Wiki article about bitcoin and its history etc. But what you need to know is that it is a currency, that is independent of country. No one really knows who invented the concept of a cryptocurrency since the person who published the paper used a nom de plume. All new cryptocurrencies work more or less the same way as Bitcoin. So as I explain below I interchange these terms. Bitcoin is the original cryptocurrency. How Bitcoin works The currency releases a coin based on a mathematical formula. There will never be more than 21 million bitcoins (other cryptocurrencies do not work like this). Each bitcoin can have divided into one hundred mil

Mindfullness Meditation and Depression - in a pod cast

Over the last 3 years I have found that meditation has really assisted me, in resolving the depression I have had. I have planned to write about my experience for a while, and hopefully will get around to doing that. However today having listen to the latest podcast by Dan Harris on 10% happier, so many things just clicked in to place, so I want to share it. To understand what is covered in the podcast I would recommend you understand what mindfulness meditation is, and what the default mode network in the brain is (see links below). Listen to the pod cast - but here are some extracts (which I do not have permission to publish - and will remove if asked).
