I have an asp.net application and can debug the application fine when I click F5 (Start Debugging), hits breakpoints, no problem. When I have a web app open and I try to attach to the w3wp.exe process, I get a message saying "Unable to attach to the process. Mixed mode debugging is not supported on Windows 64-bit platforms." Is there a way for me to attach to the process?
My asp.net application is .net 3.5, has a platform target specified as "Any CPU", and the Configuration set to debug. I am developing on Win7 x64 bit system.
VS2008 doesn't support mixed mode debugging in 64 bit (it runs in 32 bit itself).
VS2010 does support this.
Try just selecting T-SQL, Managed, x64 when attaching the remote debugger.
See a possible solution here: "Mixed mode debugging is not supported on Windows 64-bit platforms" when trying to attach to an ASP.NET process using Visual Studio 2008

I've created an ASP WebForm application that requires "Enable 32-Bit Applications" to be set to true. When I set the site up in IIS I set "Enable 32-Bit Applications" true, but when I look at the Task Manager I'm not seeing the *32 next to the w3wp.exe process that starts up. And when I browse to the site I'm getting "Service Unavailable - HTTP Error 503. The service is unavailable." as the App Pool stops within IIS.
How can I force the w3wp.exe process to start in 32 bit mode?
EDIT- The machine in question is a 64-bit Windows Server 2012 R2 in case that matters
EDIT 2- I found a link to http://www.manasbhardwaj.net/running-32-bit-web-application-iis-8/ Which references issues wile Running Sharepoint 2013, Which is running on the web server. It applied the changes, and now when I run the site I get a configuration Error regarding framework versions.
I find it odd b/c the app pool still is not showing the *32 next to it, but it didn't crash when starting the site.
I'm going to ensure the latest .NET framework is installed now.
EDIT 3- Looks like I need to run a couple of updates on the machine in order to install the latest .NET framework. The .NET framework my site uses is 4.6.1, Is this version Stable enough to run on a Live WebServer running SharePoint 2013?
I have an asp.net 3.5 solution developed on a 32-bit machine under VS2008, everything was working ok until it got migrated to a 64-bit machine, on Win7 Professional. The project has 32-bit third party dlls as well, but they are working fine on a 64-bit Windows 2008 Server. Then when trying to debug the application using VS2008 I get this error message:
Unable to start debugging on the web server. Mixed mode debugging is not supported on Windows 64-bit platforms.
Which I don't really understand since I thought the CLR was processor agnostic, anyway what would be my options now? I have read about upgrading to .net 4.0, debugging from IIS, running on VS2010, CasiniDev, etc. The project was working fine and I only need a quick work around for this.
CLR is processor agnostic it get converted to the correct version at run time; but the VS debugging plugins are not.
The 32bit/64bit-ness of the platform and what you're debugging has to match. If I remember correctly the bit-ness of the machine you're debugging from has to match too.
As it's a web application this may allow you to work around it.
I have a .net mvc web application hosted on an IIS 7.5 web server. There are several dozen other applications on this web server, all in their own application pools. ALL application pools are 64bit and things have been working fine for some time.
Last night after making a few client side changes to the site in question I published and received the error, "Could not load file or assembly 'EntityFramework.DLL or one of it's dependencies. is not a valid Win32 application. See screen below.
I ran into this error several years ago and found that by switching my app pool in IIS to 'enable 32bit applications' fixed it. This time around however, I want to understand why this is happening. There should be no reason I can't run in 64bit mode.
I know the cause could be many things so I will just list some of things I have tried. Perhaps someone has an idea where to start.
In visual studio 2013 update 4 my application is set to build for 'AnyCPU'. I have tried building exclusively for 64bit and got the same error.
I am using EF 6.1.1 with data migrations
My web server is running windows server 2008 64bit w/ iis 7.5
My development machine runs windows 7 64bit and IIS 8 express. My app works fine in this environment
I do have references to other projects that reference EF. If their version is not consistent could this be a problem?
My application targets .net 4.5 and I have that version installed on my server.
The only changes I made to this commit from the last working one were some client side code and one new migration that involved adding a new nullable string/nvarchar property to a table.
I did update to visual studio 2013 update 4 between last commit and this one.
Any ideas? Thanks ahead.
Using Win7 32-bit for 3 months and didn't have problem with developing any .NET-based applications including ASP.NET apps.
Just upgraded my laptop's RAM 3 days ago and switched to 64-bit version of Win7.
When I'm working on installing IIS7 and .NET Framework 3.5 SP1, there's an error about not all features were installed for some unknown reason.
When I try to register ASP.NET using aspnet_regiis -ir in c:\Windows\Microsft.NET\Framework64\v2.0.50727\, a dialog box shows with this error message:
"Operation failed with 0x80070643" and after I close the dialog box, another error message on the console command shows with this message: "An error has occurred: 0x80004005 Unspecified error".
I had the same problem and I did everything found on the internet but nothing was useful
eventually I was able to solve it by using the following:
note: do it on your own risk
Add the following to you registry only if the doesn't exist (in my case they didn't exist):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_2.0.50727]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_2.0.50727\Names]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_2.0.50727\Performance]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Names]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64\Performance]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64_2.0.50727]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64_2.0.50727\Names]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\ASP.NET_64_2.0.50727\Performance]
try installing asp.net 64 bit after that
Configure IIS to run in 32 bit mode (assuming your apps are 32 bit mode, since that's what you originally developed on).
http://learn.iis.net/page.aspx/201/32-bit-mode-worker-processes/
Try running aspnet_regiis after that is done. Use the 32 bit version of aspnet_regiis.
I know this is a fairly old post, but I thought I'd share what I did to solve this problem on my machine running Windows 7 64-bit.
While IIS was installed on my computer, the ASP.NET features were not enabled.
To enable ASP.NET do the following:
Navigate to the Turn Windows features on or off dialog. It's located under
Control Panel --> Programs and Features.
Note: Typing 'features' in the Start Menu search will also get you there.
When the Turn Windows features on or off dialog appears, navigate to World Wide Web Services --> Application Development Features
and make sure ASP.NET is checked.
Once this was done the aspnet_regiis -ir command worked perfectly and I could run and debug ASP.NET apps on my machine.
Hope this helps.
set IIS to run in 32 bit mode

Try running aspnet_regiis after that is done. Use the 32 bit version of aspnet_regiis.

I'm trying to set up a web page that uses both ASP Classic and ASP.NET 2.0 in the environment mentioned above. After applying many common fixes on the web and a few lucky guesses, the ASP.NET 2.0 pages are finally running fine (Minus COM+). The ASP Classic pages aren't running at all.
So I'm thinking the x64 environment is a the cause of most of my problems. Is there anyone here using old COM+ stuff with ASP Classic and ASP.NET in x64 and IIS7 with some words of wisdom?
You need to set the application pool to 32 bit mode ("Enable 32-bit Applications" in advanced properties). Set anonymous user permissions correctly. More IIS7 ASP material from learn.iis.net.
When working with x86 stuff in one of the fancy new x64 environments, look over your shoulder at every opportunity for configuration settings that need to be applied to both sides(x86/x64) of the operating system.
My problems were being caused by two groups of configuration settings that had to be set in both x64 and x86.
To enter the settings in the x86 side, here are some tips:
Copy any needed DLLs into the sysWOW64 folder.
Use a 32-bit Console to launch utilities such as the SQL Server Client Network Utility (cliconfg) and Registry Editor (regedt32). Using the 32-bit console will launch these utilities from the 32-bit system folder (%windir%\SysWoW64). I made a shortcut pointed to %windir%\SysWoW64\cmd.exe and launched it as an administrator.
