Hello,

I notice that default behavior of VS.NET 2005 is to debug asp.net applications using WebDev.WebServer.EXE. I've heard this web server referred to as "the ASP.NET Development Server" or "Cassini".

Is this really the same thing as Cassini? I see there is a separate forum devoted to Cassini.

Looking for some clarification.

Thanks!

It is indeed a derivation from the original Cassini which came with WebMatrix. It is not exactly the same since it is built with .NET 2.0 and we made a few changes to better accomodate Visual Studio. However, it is close.

Thanks Mikhail! Here's a followup question:

Do you know what algorithm VS.NET 2005 uses to select a port when debugging an ASP.NET application? I would like to know so that I can use WebDev.WebServer.EXE without VS.NET (testing and such).

If you open command promt, go to \windows\Microsoft.NET\Framework\v2.0.xxxx and run

WebDev.WebServer.EXE /?

you'll get dialog which explains how to set a fixed port number as well as other parameters.

Hello Mikhail,

I was hoping to find some more info about the WebDev.WebServer.exe because after making some changes to my Insert statement and SqlDataSource, IE 7.x could took two munites to load and finally failed and showed a WebDev.WebServer.exe error.  I can't even debug my site.  It fails everytime I login.  I made too many changes to know which one is causing this, if any are.  My VWD has also been hanging a lot resently and showing a "busy" message in my start panel (I forget the exact text but it's not an error).  Any suggestions?

I don't think this problem was caused by WebDEV.WebServer.In fact, it caused by IE7, I have the same problem for a quite long time since I installed IE 7 beta 2 first time, after IE 7 beta 3 was released, it still has the same problem. My solution is to use Firefox as a default browser, you will find it's very fast.Alternatively, you uninstall IE 7, keep IE 6 running again until IE 7 rtm was released

The install of IE7 should not have affected the time to insert into a database. Please try starting debugging the page with an F5. When the browser is waiting on the server, hit the break button in VS. You should then have the callstack for the server. If you post we can start to diagnose where the problem may be.

Have you also installed any new firewall / ad blocker / virus scanning software recently?
