i try to publish and i get an error

someone know how to resolve ?
thank you
It looks like your IIS settings are not matching.
If you go to your IIS Manager and navigate to Application Pools and look for the published(your Project name) folder
Select your Published project from the list
Click on Basic Settings from Actions pane
Change the .NET Framework Version to v4.0xxxxx
Had the same problem when installing Orchard CMS. Keep targeting v2.0.
But find the simple solution: in IIS, on the Application Pools (the list with all application pools), you can find the 2nd setting top right list: "Set Application Pool Defaults.." change there the default from 2.0 to 4.0 et, voila.
It sounds like your project is targeting the .net 4.0 framework, but there is a setting in your 'publish' flow that specifies .net 2.0
I've never published this way, but this error looks like something I've seen before integrating different libraries targeting different frameworks...
Solved:
All above didn't solve my problem , just changed Targeted Framework in visual studio from 4.5 to 4.5.1 and Problem Solved

Hello i have a ASP Net Core 5.0 web api which i am trying to deploy to azure and i can't because it says it is not yet supported.
However following the MSDN and similar threads ( when the same issue was valid for .NET Core 3.1) i understood that you can publish it with the option to be self-contained.
It still does not work:
Application Logs
VStudio Publish
Any idea on how to publish my application to azure ?
Later Edit
I forgot to mention all calls to my web api return a 404 message.
So if my
[indexurl] returns the microsoft page
[Indexurl]/[some path] returns 404 (which i understood from github is a 500 actually)
What should i understand ? The web api works , or it doesnt and where could the problem be ?
ASP NET Core 5.0 not supported in Azure
After testing, azure webapp currently supports ASP.NET Core 5.0.
According to your description, I conducted a test, first tested under windows, it was normal. Then deployed and tested under Linux, it is normal.
I guess the reasons may be the following two:
There is a problem with your .Net 5.0 installation. It may be used when compiling, if necessary, and cause compilation exception and release failure. (The possibility is relatively low)
It is possible that the webapi created by default does not have a default index page, so you feel that it is not supported. In fact, you can use webapp for testing, or you can write an interface for testing yourself.
The VS2019 version I used for testing is Microsoft Visual Studio Enterprise 2019 Version 16.8.2. And I installed .net 5.0 Runtime on the machine.
For your question, describe in detail the steps of testing under Linux:
Step 1. Create Core5.0 Webapi Project.
Step 2. Test in local, and it works fine.
Step 3. Deploy to azure with Deployment mode is Framework-dependent.
And test it, it look likes something wrong because the project don't set default route, and I input the WeatherForecast to access default interface, it works.
Step 4. Deploy to azure with Deployment mode is Self-Contained like you pic.
And it also works fine.
I have a small web app developed with Asp.Net Core 1.1 deployed on Azure and it works well. I just migrated the project to use Asp.Net Core 2.0 and tried to deploy it on Azure. The deployment went fine but when I open the site, I get a 502.5 error. When I check my Azure log stream, I get the following error:
This error occurs when a CGI application does not return a valid set
of HTTP headers, or when a proxy or gateway was unable to send the
request to a parent gateway. You may need to get a network trace or
contact the proxy server administrator, if it is not a CGI problem.
Useless to say that it works well on my development machine with the same code. Note that I'm also using Entity Framework Core 2.0 although I deactivated the database creation on Azure (to check if it was not the cause).
For information, the way I migrated from 1.1 to 2.0 is by changing the target framework settings to "netcoreapp2.0" and by using the NuGet package "Microsoft.AspNetCore.All". Just to be sure, I also deleted my publish profile and recreate one.
Is it possible that Asp.Net Core 2.0 is not yet available on Azure ? I'm fairly new to Asp.Net Core, so I don't know when new releases are made available on Azure.
EDIT
When I try to run my app with dot net CLI via the debug console as proposed by natemcmaster, I got the following issue:
Unhandled Exception: System.IO.FileLoadException: Could not load file
or assembly 'Microsoft.AspNetCore.Hosting.Abstractions,
Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.
The located assembly's manifest definition does not match the assembly
reference. (Exception from HRESULT: 0x80131040)
I downloaded the DLL on my desktop and check the version with Dot Net Peak and indeed, the DLL is 1.1.2, although I created the project with Visual Studio and directly publish it, so is it an issue with Visual Studio ? Or Nuget ?
the issue was actually coming from the fact that, at first, my web app was using .net core 1.1, which deploys all the DLL in the "wwwroot" folder of the web application. However, with asp.net core 2.0, it does not do that anymore as the DLL are picked up from a global store. However, as Visual Studio does not clean the destination folder before a publish, I ended up with a situation where the 1.1 DLL were in my wwwroot, so the web site was picking up these ones instead of the 2.0 ones in the store folder.
This is explained in more details here: https://github.com/Azure/app-service-announcements-discussions/issues/2#issuecomment-313816550
Others have explained the reason why this is happening. I'd like to provide another – arguably easier – solution to the problem.
Just change the settings so that you remove files that are already on Azure – see below:
Check for log files either in the portal or by remotely accessing D:\home\LogFiles.
Sometimes, the logs won't indicate what is going wrong. Another good way to investigate further is to try launching your ASP.NET Core app from the Debug Console. If you are missing a shared framework version or there is another startup error, this will be more visible from the Debug Console.
Go to
https://(your web site name here).scm.azurewebsites.net/DebugConsole/
Your site will be in D:\home\site\wwwroot. You can launch it by executing:
cd D:\home\site\wwwroot
dotnet MyWebApp.dll
If you app still fails to launch, make sure that D:\home\site\wwwroot\web.config is available and configured to use ASP.NET Core Module. https://learn.microsoft.com/en-us/aspnet/core/hosting/aspnet-core-module
In my case, It was caused by having a space in the Project Name.
I can readily add a space, publish => 502.5.
Remove space, publish => good to go.
Hard to believe but I am duplicating it readily with above.
Also using "Remove Additional Files at Destination" per #Sam's Answer
See https://github.com/Azure/app-service-announcements/issues/14
"The rollout is expected to complete by Friday June 30th."
In my case the issue occurred because AppService at that time supported 2.0.0-preview2-006497 but I had 2.0.0-preview3-006890 installed which was used on build.
So I added global.json to use preview 2 SDK and it worked then
I don't know if this could help someone one day but in my case, I was using :
-Microsoft.AspNetCore.All 2.0.5
Downdrage to Microsoft.AspNetCore.All 2.0.3 resolve my problem
This happens when your version of ASP.NET Core cannot be matched on the server.
The simplest solution is to change your settings to deploy the app as self-contained, so it doesn't matter if Azure can match the framework version. Also, delete the files already on Azure, so you don't have issues when upgrading, as explained by #Sam.
Any idea how to run ASP.NET 5 project in full IIS (not express) from within Visual Studio 2015 (via start debugging with F5 key)?
Atm I'm getting:
Couldn't determine an appropriate version of KRE to run.
I know it's not officially supported yet, but since IIS Express can do it, so should full IIS?!?
Let's say you created an ASP.NET 5 web application out of the template provided in VS 2015 Preview, then you can follow either of the approaches below:
Run the kpm pack command to create the deployable package with the appropriate options.
Example:
kpm pack --runtime KRE-CLR-x86.1.0.0-beta2-10690 --out "C:\MyWebApps\WebApplication1" --wwwroot-out wwwroot --configuration Release
Right click on the web application project and do a Publish to local file system directory.
Once the above step is done, in IIS, you can create a virtual directory application (or Website if you wish) to this deployable package's wwwroot folder. Example: "C:\MyWebApps\WebApplication1\wwwroot"
I just had a similar issue with beta4.
Note that the names have changed now so instead of a KRE it's now a DNX, although IIS was still showing the error calling it KRE despite this.
Anyway the solution for me was to:
right click the project in question in Solution Explorer
select "project name" Properties
tick Use Specific DNX version
tell it exactly which one you want to use, for me that was 1.0.0-beta4, .NET Core, x64
The project then ran in the browser for me.
I have a web application asp.net to deploy to Windows Azure. I try to run it on local first. But when debugging, I catch this error from VS2010:
"There was an error attaching the debugger to the IIS worker process
for URL 'http://127.255.0.0:82/' for role instance
'deployment16(6).WindowsAzureProject2.WebApplication3_IN_0'.
Unable to start debugging on the web server ......."
I've search so hard to find the solution for this problem but there's nothing seems work for me. I'm a newbie in Windows Azure, it's really a big trouble with me.
I had similar problem with Windows 8, debuging a cloud application with Visual Studio 2012 RTM and Azure SDK 1.71, when trying to launch the application into the compute emulator. It was a very simple app, but I used Azure diagnostics. At the end these are two things I have changed that have work for me, both turning on Windows 8 features (so go to Win8 and open 'Turn Windows Features On/Off'.
Activate the checkboxes for:
Internet Information Services Hostable Web Core
Internet Information Services > World Wide Web Services > Application Development Features > ASP.NET 4.5
Internet Information Services > World Wide Web Services > Health and Diagnostics > Tracing
Internet Information Services > Web Management Tools > IIS Management Scripts and Tools
That worked for me, it makes sense, as I'm using Visual Studio 2012 and trying to get some trace information using diagnostics in Azure.
I hope this will work for you or give some tip about the problem. In the case of being useful information, remember to vote as response or as value tip.
Thanks,
Mike
This usually happens when there's a problem with the project to be deployed to the emulator (WindowsAzureProject2 in your case).
Try the following:
Check %UserProfile%\AppData\Local\dftmp\IISConfiguratorLogs\IISConfigurator.log file for the error messages. See more details in this answer.
Make sure your project can be started without the emulator. It's a web project, so just try to start it as a regular web project. Or publish it to the separate folder and try to create a website in IIS of it.
Check your *.csdef and *.cscfg files to make sure all the configuration is correct.
Make sure that the build output of your project is not empty. You can do this by going to IIS, find the site with the name similar to deployment16(6).WindowsAzureProject2.WebApplication3_IN_0, right click --> Explore.... Make sure that this folder is not empty and contains all the files required to start a web project successfully.
BTW, there's a similar question: Debugger can't connect when starting local azure project
Follow step 11 from http://www.microsoft.com/en-us/download/details.aspx?id=35448. Worked for me on Windows 8 with Oct 2012 SDk
I just have today the same problem trying to Debug locally with Azure Storage Emulator in Windows 7. So in the Azure project properties, in Web tab, I checked the radio button 'Use IIS Express' and it debugged without problem. I hope this helps someone.
I encountered this exact same problem when I upgraded an existing Azure solution to the Azure SDK 2.1. After some hunting around I uncovered that the upgrade had automatically set the "Local Development Server" setting to "Use IIS Web Server".
Changing the "Local Development Server" setting to "Use IIS Express" fixed the problem immediately.
To access this setting right-click the Azure cloud project file in your solution, select the "Properties" option, tab down to "Web" and you'll see the following setup.
Also, make sure you run Visual Studio as administrator
Please check the version of emulator you have installed. If your code is created in older sdk and you have a new emulator installed it will give you this error.
Check the version of Azure APIs in your project, go to Project > references and right click on Azure dlls to check the version, same sdk version must be installed on the system, higher are optional as azure 2.x are not backward compatible.
If I have more than one webroles(projects, not instances) in my application, I get this error: (I only get it if I attach a web role. It works fine wit as many worker roles projects as I want)
Microsoft Visual Studio
Windows Azure Tools for Microsoft Visual Studio
There was an error attaching the debugger to the IIS worker process for URL 'http://127.0.0.1:5100/' for role instance 'deployment(21).CloudPOC.WebRoleToHostDataService.0'. Unable to start debugging on the web server. The web server is not configured correctly. See help for common configuration errors. Running the web page outside of the debugger may provide further information.
Click Help for more information.
OK
What is wrong here? I can't understand it and I need a webservice project!
Make sure you are starting the Azure project rather than the Web Project itself. You might have set the Web Role as the startup project, and if you do that you'll find that IIS runs the Web App rather than the Azure Dev Fabric, meaning any Dev Fabric specific stuff (like config settings per role) aren't available causing problems.
What you're meant to do is let the Azure Dev Fabric (Compute Simulator) fire up all your roles for you, and it'll also work out if it needs to open a web browser etc.
So right click on the Azure Cloud project, set that as the Startup Project, and try again.
Hope that helps,
Andy
EDIT thought of something else!
Make sure your web.config is compiling to allow debug="true". If you have added a new WebSite to your solution, it won't be so by default:
<system.web>
<compilation debug="true" targetFramework="4.0" />
I had similar issue which got resolved with following steps.
Make sure you have correct version of .net framework 4.0 is intalled. (.Net Framework 4.0.30319 is the latest version)
Uninstall if there isany other .Net 4.0 framework in present on your system by going to Add And Remove programs.
Go to %windir%\Microsoft.NET\Framework64 physical location and remove unwanted .Net framework 4.0 folder
I've also had this problem and it happened when I upgraded my app to 4.0... I ran without debugging and got the following error:
There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined
and after researching that error, I found this:
http://forums.asp.net/t/1571308.aspx/1
which says there's currently a bug w/ vs2010 and 4.0... I took the answers recommendation and commented out the extensions section and it worked for me... Another possible solution.
