why can't i attach a process in asp.net - asp.net

when i am trying to attach a process(w3wp.exe) in asp.net (visual studio 2008), i couldn't attach it , it displays the following error
i have repaired the visual studio 2008, after seen this. again i got the same error as shown above when i am trying to attach a new one.
why this happens, is i need to download any other service pack or visual studio 2008 remote debugger installation ( as mentioned in the error box),. please help me to fix it.

According to here, there should be a remote debugger setup file on the VS2008 disc in a folder called "Remote Debugger\x64" or "WCU\RDBG\x64".
You could also try downloading and installing the Visual Studio 2008 Service Pack 1 Remote Debugger.

Unable to see biztalk project template in Visual Studio 2013 Ultimate

I have installed BizTalk 2013 R2 on Windows Server 2012 R2 and Visual Studio 2013 Ultimate is also installed on the same machine.
I cannot see BizTalk Project template while creating a new project in Visual Studio.
When I ran the BizTalk setup again, Developer Tools box was not selected. When I select the box it gives following message
Features you selected requires the following components to be installed:
WCF HTTP ACTIVATION 4.5, IIS ASP NET 4.5
When I check in the Server Manager, both of the above are already installed.
Kindly help me resolve this issue.
Have you registered ASP.NET 4.5 on the machine?
Try running this command:
aspnet_regiis -i
You can read more about the ASP.NET IIS Registration Tool (Aspnet_regiis.exe) here:
http://msdn.microsoft.com/en-us/library/k6h9cz8h%28v=vs.100%29.aspx
The easiest way to do this would be to run the Visual Studio Command Prompt.
Also make sure to run as an administrator.
To restore the default project templates
In the command prompt, navigate to the location of devenv.exe. This file is located in \Common7\IDE.
Type "devenv /installvstemplates" and press Enter.
NoteNote:
If you are using an Express Edition of Visual Studio, type "Express /installvstemplates" where is either VB, VJS, or VCS for Visual Basic, Visual J#, and Visual C#, respectively.
If this procedure does not restore the default templates, reinstall Visual Studio.

Object reference is not set to an instance of an object on creating windows phone app

When i tried to create a windows phone application on visual studio 2012 i get the error "Object reference is not set to an instance of an object". I searched on google and find that deleting the 'NuGet packet manager' will solve the issue. But after deleting the packet manager i got the same error. What should i do to create the app.?
it appears that your windows phone development kit along with your visual studio is messed up. Try running the Visual Studio setup again and choose repair your installation. Once done, try creating the windows app again.
Thanks
Reinstall your Windows phone SDK toolkit or repair it. If still your are getting same issue try to repair your visual studio 2012 from control panel.
Note: Please close your visual studio before repair.

how to run aspx files on windows XP

I have windows xp service pack 3 so i cannot download some of the proggrams.
I downloaded the next proggrams:
*visual c++ 2005 express edition(by the way it's imposibble to find the visual studio express edition of 2005 on microsoft download center)
*microsoft web platformer installer
*windows installer
*microsoft .net framework 2.0 service pack 1
*microsoft sql server 2005 express edition
and i still cannot run aspx files. everytime im trying to open an aspx file it opens it as text file, and doesnt allow me to run it(the file worked on other computers).
I assume the problem is in my visual studio version, can someone give me a link to a visual studio that will work for me(p.s if I need to download new sql server proggram or net framework I'll appriciate if you tell me as well).
and remember that I have winxp so I cant download visual studio 2012(p.s there is a way you can somehow devolop without paying for the software?)
any help will be apperciate.
Tnx Dean.
You need Visual Studio Web Developer Express and not Visual C++ Express Edition. Here is the link http://go.microsoft.com/fwlink/?LinkId=51413&clcid=0x409
And here you have 2008 - should work on XP too - http://www.asp.net/downloads/essential

Unable to connect to ASP.NET development server error visual studio 2010

When I am trying to run my asp.net project it is giving me error as:

It was working well one day ago, but after I uninstalled and re-installed Visual Studio, now it is showing me Error in visual studio.I have no idea about this error please help me in this regard. Any help regarding this will be strongly appreciated.
Even I faced this problem. while installing the visual studio 2010 we need to install IIS component.Follow the steps for installing "IIS 6 management capability".
1.goto control panel>>Turned windows features on or OFF>>
2.Internet information services >> web management tools>> check out checkbox (IIS management console)

Failed to Map Path '/doc'. server.map path

If I run the site using the internal Visual Studio web server, I get the failed to map path error.
It seems to be a security problem.
I assume you use Vistual Studio 2008 and Vista or Windows Seven.
Launch Visual Studio with the administrator right, and the problem should disappear.
