Trying to install .NET CORE 3.0 extension for my App Services inside my App Service Environment (ASE):
Using the portal:
I get
However the extension is not installed!
How to get this to work?
Please note: Azure App Services running in App Service Environment
To ensure the extension is installed, in Kudu, check the directory in D:\home\SiteExtensions\AspNetCoreRuntime.3.0.x64.
Once confirmed you can edit your web.config to point to the site extension as follows as a workaround
<aspNetCore processPath="D:\home\SiteExtensions\AspNetCoreRuntime.3.0.x86\dotnet" arguments=".\<project output>.dll" stdoutLogEnabled="true" stdoutLogFile="\\?\%home%\LogFiles\stdout" hostingModel="inprocess" />
See https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-3.0#webconfig-file for more info.
It does seem this should be handled by the extension itself so there could be a problem there. Nonetheless, .NET Core 3 should be deployed in the next week or so as an available runtime.
EDIT:
You add the 'Use .NET Core' task in Azure Pipelines
to install the 3.0 SDK. This, in conjunction with --self-contained true --runtime <RID> in the Publish task and <AspNetCoreHostingModel>OutOfProcess</AspNetCoreHostingModel> in your csproj is an alternative to using the extension.
Firstly if you could not install it you could go to you app kudu site to install it.
Secondly if you just want to make your .net core 3 web run in Azure, actually there is a tutorial about how to deploy ASP.NET Core 3.0 to Azure App Service.
I test these two, they all could work. Just if you deploy with Framework-Dependent way, it will show you a error message like the below pic, however the web will work.
Note:With Framework-Dependent way, you have to install the extension, and if you use Self-Contained way, you don't have to do it.
