# Host ASP.NET Core on Azure App Service
|
||||
|
||||
The following articles are available for learning about hosting ASP.NET Core apps in Azure App Service:
|
||||
[Azure App Service](https://azure.microsoft.com/services/app-service/) is a [Microsoft cloud computing platform service](https://azure.microsoft.com/) for hosting web apps, including ASP.NET Core.
|
||||
|
||||
## Useful resources
|
||||
|
||||
The Azure [Web Apps Documentation](/azure/app-service/) is the home for Azure Apps documentation, tutorials, samples, how-to guides, and other resources. Two notable tutorials that pertain to hosting ASP.NET Core apps are:

## Application configuration
|
||||
|
||||
With ASP.NET Core 2.0 and later, three packages in the [Microsoft.AspNetCore.All metapackage](xref:fundamentals/metapackage) provide automatic logging features for apps deployed to Azure App Service:
|
||||
|
||||
* [Microsoft.AspNetCore.AzureAppServices.HostingStartup](https://www.nuget.org/packages/Microsoft.AspNetCore.AzureAppServices.HostingStartup/) uses [IHostingStartup](xref:host-and-deploy/ihostingstartup) to provide ASP.NET Core lightup integration with Azure App Service. The added logging features are provided by the `Microsoft.AspNetCore.AzureAppServicesIntegration` package.
|
||||
* [Microsoft.AspNetCore.AzureAppServicesIntegration](https://www.nuget.org/packages/Microsoft.AspNetCore.AzureAppServicesIntegration/) executes [AddAzureWebAppDiagnostics](/dotnet/api/microsoft.extensions.logging.azureappservicesloggerfactoryextensions.addazurewebappdiagnostics) to add Azure App Service diagnostics logging providers in the `Microsoft.Extensions.Logging.AzureAppServices` package.
|
||||
* [Microsoft.Extensions.Logging.AzureAppServices](https://www.nuget.org/packages/Microsoft.Extensions.Logging.AzureAppServices/) provides logger implementations to support Azure App Service diagnostics logs and log streaming features.
|
||||
|
||||
## Monitoring and logging
|
||||
|
||||
For monitoring, logging, and troubleshooting information, see the following articles:
|
||||
|
||||

|
||||
See the common deployment configuration errors for apps hosted by Azure App Service/IIS with troubleshooting advice.
|
||||
|
||||
## Data Protection key ring and deployment slots
|
||||
|
||||
[Data Protection keys](xref:security/data-protection/implementation/key-management#data-protection-implementation-key-management) are persisted to the *%HOME%\ASP.NET\DataProtection-Keys* folder. This folder is backed by network storage and is synchronized across all machines hosting the app. Keys aren't protected at rest. This folder supplies the key ring to all instances of an app in a single deployment slot. Separate deployment slots, such as Staging and Production, don't share a key ring.
|
||||
|
||||
When swapping between deployment slots, any system using data protection won't be able to decrypt stored data using the key ring inside the previous slot. ASP.NET Cookie Middleware uses data protection to protect its cookies. This leads to users being signed out of an app that uses the standard ASP.NET Cookie Middleware. For a slot-independent key ring solution, use an external key ring provider, such as:
|
||||
|
||||
* Azure Blob Storage
|
||||
* Azure Key Vault
|
||||
* SQL store
|
||||
* Redis cache
|
||||
|
||||
For more information, see [Key storage providers](xref:security/data-protection/implementation/key-storage-providers).

# Troubleshoot ASP.NET Core on Azure App Service
|
||||
|
||||
This topic is under development the week of January 8, 2018 and will appear soon.
|
||||
By [Luke Latham](https://github.com/guardrex)
|
||||
|
||||
This article provides instructions on how to diagnose an ASP.NET Core app startup issue using Azure App Service's diagnostic tools. For additional troubleshooting advice, see [Azure App Service diagnostics overview](/azure/app-service/app-service-diagnostics) and [How to: Monitor Apps in Azure App Service](/azure/app-service/web-sites-monitor) in the Azure documentation.
|
||||
|
||||
## App startup errors
|
||||
|
||||
**502.5 Process Failure**
|
||||
The worker process fails. The app doesn't start.
|
||||
|
||||
The [ASP.NET Core Module](xref:fundamentals/servers/aspnet-core-module) attempts to start the worker process but it fails to start. Examining the Application Event Log often helps troubleshoot this type of problem. Accessing the log is explained in the [Event log](#event-log) section.
|
||||
|
||||
The *502.5 Process Failure* error page is returned when a misconfigured app causes the worker process to fail:
|
||||
|
||||
|
||||
|
||||
**500 Internal Server Error**
|
||||
The app starts, but an error prevents the server from fulfilling the request.
|
||||
|
||||
This error occurs within the app's code during startup or while creating a response. The response may contain no content, or the response may appear as a *500 Internal Server Error* in the browser. The Application Event Log usually states that the app started normally. From the server's perspective, that's correct. The app did start, but it can't generate a valid response. [Run the app in the Kudu console](#run-the-app-in-the-kudu-console) or [enable the ASP.NET Core Module stdout log](#aspnet-core-module-stdout-log) to troubleshoot the problem.
|
||||
|
||||
## Troubleshoot app startup errors
|
||||
|
||||
### Application Event Log
|
||||
|
||||
To access the Application Event Log, use the **Diagnose and solve problems** blade in the Azure portal :
|
||||
|
||||
1. In the Azure portal, open the app's blade in the **App Services** blade.
|
||||
1. Select the **Diagnose and solve problems** blade.
|
||||
1. Under **SELECT PROBLEM CATEGORY**, select the **Web App Down** button.
|
||||
1. Under **Suggested Solutions**, open the pane for **Open Application Event Logs**. Select the **Open Application Event Logs** button.
|
||||
1. Examine the latest error provided by the *IIS AspNetCoreModule* in the **Source** column.
|
||||
|
||||
An alternative to using the **Diagnose and solve problems** blade is to examine the Application Event Log file directly using [Kudu](https://github.com/projectkudu/kudu/wiki):
|
||||
|
||||
1. Select the **Advanced Tools** blade in the **DEVELOPMENT TOOLS** area. Select the **Go→** button. The Kudu console opens in a new browser tab or window.
|
||||
1. Using the navigation bar at the top of the page, open **Debug console** and select **CMD**.
|
||||
1. Open the **LogFiles** folder.
|
||||
1. Select the pencil icon next to the *eventlog.xml* file.
|
||||
1. Examine the log. Scroll to the bottom of the log to see the most recent events.
|
||||
|
||||
### Run the app in the Kudu console
|
||||
|
||||
Many startup errors don't produce useful information in the Application Event Log. You can run the app in the [Kudu](https://github.com/projectkudu/kudu/wiki) Remote Execution Console to discover the error:
|
||||
|
||||
1. Select the **Advanced Tools** blade in the **DEVELOPMENT TOOLS** area. Select the **Go→** button. The Kudu console opens in a new browser tab or window.
|
||||
1. Using the navigation bar at the top of the page, open **Debug console** and select **CMD**.
|
||||
1. Open the folders to the path **site** > **wwwroot**.
|
||||
1. In the console, run the app by executing the app's assembly with *dotnet.exe*. In the following command, substitute the name of the app's assembly for `<assembly_name>`:
|
||||
```console
|
||||
dotnet .\<assembly_name>.dll
|
||||
```
|
||||
1. The console output from the app, showing any errors, is piped to the Kudu console.
|
||||
|
||||
### ASP.NET Core Module stdout log
|
||||
|
||||
The ASP.NET Core Module stdout log often records useful error messages not found in the Application Event Log. To enable and view stdout logs:
|
||||
|
||||
1. Navigate to the **Diagnose and solve problems** blade in the Azure portal.
|
||||
1. Under **SELECT PROBLEM CATEGORY**, select the **Web App Down** button.
|
||||
1. Under **Suggested Solutions** > **Enable Stdout Log Redirection**, select the button to **Open Kudu Console to edit Web.Config**.
|
||||
1. In the Kudu **Diagnostic Console**, open the folders to the path **site** > **wwwroot**. Scroll down to reveal the *web.config* file at the bottom of the list.
|
||||
1. Click the pencil icon next to the *web.config* file.
|
||||
1. Set **stdoutLogEnabled** to `true` and change the **stdoutLogFile** path to: `\\?\%home%\LogFiles\stdout`.
|
||||
1. Select **Save** to save the updated *web.config* file.
|
||||
1. Make a request to the app.
|
||||
1. Return to the Azure portal. Select the **Advanced Tools** blade in the **DEVELOPMENT TOOLS** area. Select the **Go→** button. The Kudu console opens in a new browser tab or window.
|
||||
1. Using the navigation bar at the top of the page, open **Debug console** and select **CMD**.
|
||||
1. Select the **LogFiles** folder.
|
||||
1. Inspect the **Modified** column and select the pencil icon to edit the stdout log with the latest modification date.
|
||||
1. When the log file opens, the error is displayed.
|
||||
|
||||
**Important!** Disable stdout logging when troubleshooting is complete.
|
||||
|
||||
1. In the Kudu **Diagnostic Console**, return to the path **site** > **wwwroot** to reveal the *web.config* file. Open the **web.config** file again by selecting the pencil icon.
|
||||
1. Set **stdoutLogEnabled** to `false`.
|
||||
1. Select **Save** to save the file.
|
||||
|
||||
> [!WARNING]
|
||||
> Failure to disable the stdout log can lead to app or server failure. There's no limit on log file size or the number of log files created.
|
||||
>
|
||||
> For routine logging in an ASP.NET Core app, use a logging library that limits log file size and rotates logs. For more information, see [third-party logging providers](xref:fundamentals/logging/index#third-party-logging-providers).
|
||||
|
||||
## Common startup errors
|
||||
|
||||
See the [ASP.NET Core common errors reference](xref:host-and-deploy/azure-iis-errors-reference). Most of the common problems that prevent app startup are covered in the reference topic.
|
||||
|
||||
## Process dump for a slow or hanging app
|
||||
|
||||
When an app responds slowly or hangs on a request, see [Troubleshoot slow web app performance issues in Azure App Service](/azure/app-service/app-service-web-troubleshoot-performance-degradation) for debugging guidance.
|
||||
|
||||
## Remote debugging
|
||||
|
||||
See [Remote debugging web apps section of Troubleshoot a web app in Azure App Service using Visual Studio](/azure/app-service/web-sites-dotnet-troubleshoot-visual-studio#remotedebug) in the Azure documentation.
|
||||
|
||||
## Application Insights
|
||||
|
||||
[Application Insights](https://azure.microsoft.com/services/application-insights/) provides telemetry from apps hosted in the Azure App Service, including error logging and reporting features. Application Insights can only report on errors that occur after the app starts when the app's logging features become available. For more information, see [Application Insights for ASP.NET Core](/azure/application-insights/app-insights-asp-net-core).
|
||||
|
||||
## Monitoring blades
|
||||
|
||||
Monitoring blades provide an alternative troubleshooting experience to the methods described earlier in the topic. These blades can be used to diagnose 500-series errors.
|
||||
|
||||
Confirm that the ASP.NET Core Extensions are installed. If the extensions aren't installed, install them manually:
|
||||
|
||||
1. In the **DEVELOPMENT TOOLS** blade section, select the **Extensions** blade.
|
||||
1. The **ASP.NET Core Extensions** should appear in the list.
|
||||
1. If the extensions aren't installed, select the **Add** button.
|
||||
1. Choose the **ASP.NET Core Extensions** from the list.
|
||||
1. Select **OK** to accept the legal terms.
|
||||
1. Select **OK** on the **Add extension** blade.
|
||||
1. An informational pop-up message indicates when the extensions are successfully installed.
|
||||
|
||||
If stdout logging isn't enabled, follow these steps:
|
||||
|
||||
1. In the Azure portal, select the **Advanced Tools** blade in the **DEVELOPMENT TOOLS** area. Select the **Go→** button. The Kudu console opens in a new browser tab or window.
|
||||
1. Using the navigation bar at the top of the page, open **Debug console** and select **CMD**.
|
||||
1. Open the folders to the path **site** > **wwwroot** and scroll down to reveal the *web.config* file at the bottom of the list.
|
||||
1. Click the pencil icon next to the *web.config* file.
|
||||
1. Set **stdoutLogEnabled** to `true` and change the **stdoutLogFile** path to: `\\?\%home%\LogFiles\stdout`.
|
||||
1. Select **Save** to save the updated *web.config* file.
|
||||
|
||||
Proceed to activate diagnostic logging:
|
||||
|
||||
1. In the Azure portal, select the **Diagnostics logs** blade.
|
||||
1. Select the **On** switch for **Application Logging (Filesystem)** and **Detailed error messages**. Select the **Save** button at the top of the blade.
|
||||
1. To include failed request tracing, also known as Failed Request Event Buffering (FREB) logging, select the **On** switch for **Failed request tracing**.
|
||||
1. Select the **Log stream** blade, which is listed immediately under the **Diagnostics logs** blade in the portal.
|
||||
1. Make a request to the app.
|
||||
1. Within the log stream data, the cause of the error is indicated.
|
||||
|
||||
**Important!** Be sure to disable stdout logging when troubleshooting is complete. See the instructions in the [ASP.NET Core Module stdout log](#aspnet-core-module-stdout-log) section.
|
||||
|
||||
To view the failed request tracing logs (FREB logs):
|
||||
|
||||
1. Navigate to the **Diagnose and solve problems** blade in the Azure portal.
|
||||
1. Select **Failed Request Tracing Logs** from the **SUPPORT TOOLS** area of the sidebar.
|
||||
|
||||
See [Failed request traces section of the Enable diagnostics logging for web apps in Azure App Service topic](/azure/app-service/web-sites-enable-diagnostic-log#failed-request-traces) and the [Application performance FAQs for Web Apps in Azure: How do I turn on failed request tracing?](/azure/app-service/app-service-web-availability-performance-application-issues-faq#how-do-i-turn-on-failed-request-tracing) for more information.

# Resource-based authorization
|
||||
|
||||
By [Scott Addie](https://twitter.com/Scott_Addie)
|
||||
|
||||
Authorization strategy depends upon the resource being accessed. Consider a document which has an author property. Only the author is allowed to update the document. Consequently, the document must be retrieved from the data store before authorization evaluation can occur.
|
||||
|
||||
Attribute evaluation occurs before data binding and before execution of the page handler or action which loads the document. For these reasons, declarative authorization with an `[Authorize]` attribute won't suffice. Instead, you can invoke a custom authorization method—a style known as imperative authorization.
|
||||
|
||||
Use the [sample apps](https://github.com/aspnet/Docs/tree/master/aspnetcore/security/authorization/resourcebased/samples) ([how to download](xref:tutorials/index#how-to-download-a-sample)) to explore the features described in this topic.
|
||||
|
||||
[Create an ASP.NET Core app with user data protected by authorization](xref:security/authorization/secure-data) contains a sample app that uses resource-based authorization.
|
||||
|
||||
## Use imperative authorization
|
||||
|
||||
Authorization is implemented as an [IAuthorizationService](/dotnet/api/microsoft.aspnetcore.authorization.iauthorizationservice) service and is registered in the service collection within the `Startup` class. The service is made available via [dependency injection](xref:fundamentals/dependency-injection#fundamentals-dependency-injection) to page handlers or actions.

If you lose your device and don't have the recovery codes you will lose access to your account.

Generating new recovery codes does not change the keys used in authenticator apps. If you wish to change the key
|

used in an authenticator app you should <a asp-action="ResetAuthenticatorWarning">reset your authenticator keys.</a>
