Hey guys,
Can someone help me:
When I install Visual Web Developer, it installs the .NET Framework 2.0.50215.44 along with it, and it seems to work okay.
However, when I then went on to install SQL Server, it required the .NET Framework 2.0.50727.26. After installing this, SQL Server would work, but Visual Web Developer would not.
--So with 2.0.50727.26: SQL Server will work; Visual Web Developer won't
--And with 2.0.50215.44, SQL won't, but Visual Web Developer will.
Basically, the message says it is unable to connect to Visual Studio's Localhost web server. Trying to do anything gives me packet load errors.
Has anyone else had this problem or does anyone have any ideas
Cheers!

Hello All,
(I posted this on ASP.Net forum and I thought I'd post the following here as well).
I experienced the similar (Unable to connect to Visual Studio's Localhost Web Server) error too, after I installed/uninstalled various versions of .Net redistributable binaries. After much trial and error, I figured the cause of the problem-
1. First check the number of .Net (redistributable) versions you have installed within the Windows directory.
2. Then make sure that you repair or reinstall each of those run-time versions. For example, in my case I had the versions v2.0.50215 and v2.0.50727 on my machine; but, version v2.0.50215 had some issues.
Since my web site was originally compiled using this older version, IIS was looking for that version's runtime and hence the could not launch WebDev.WebServer.EXE successfully.
3. So, I reinstalled the v2.0.50215 redistributable on my machine; since, I am able to run my web site without any issues. So, just make sure that you have the correct version of the redistributables installed on your machine.
Note: I may be wrong here but, techinically, if I got rid of my web site's binaries and recompiled my web site, my web site would probably work as it would use the latest .Net version (v2.0.50727).
Hope this helps!

I am having the same problem but the solution provided does not help me as I do not have the multiple versions on my machine.
I don't want to double post, but I thought I could point to that discussion here:
