I have followed this tutorial to deploy a .NET Core console application to an Azure Web Service WebJob.
My app is running locally without any issue (with dotnet 1.0.0-preview2-003131) but when I try to run it from Azure console I have the following error :
Failed to load the dll from [D:\local\VirtualDirectory0\site\wwwroot\app_data\jobs\triggered\PopcornExportWebJob\hostpolicy.dll], HRESULT: 0x800700C1
An error occurred while loading required library hostpolicy.dll from [D:\local\VirtualDirectory0\site\wwwroot\app_data\jobs\triggered\PopcornExportWebJob]
The version of Azure dotnet is 1.0.0-rc4-004771 and the hostpolicy.dll file is the same than I use locally. In fact, when I download the zip of my deploy from Azure and when I run it locally, it is working fine. But it fails on Azure environment.
Also, here is my project.json:
{
"publishOptions": {
"include": [
"run.cmd"
]
},
"buildOptions": {
"emitEntryPoint": true,
"copyToOutput": "appsettings.json"
},

},
"title": "PopcornExport",
"version": "1.0.0-*"
}
I had to add the node runtimes (win10-x64 otherwise the app can't run locally). But, the Azure Web Service is running on Windows Server 2012. May it be an issue?
What did I miss?
Alright, I've figured it out.
If you want to deploy a dotnet core app to Azure Web Service, include the runtime "win7-x86" if you are running your app in 32-Bit platform mode.
For a Visual Studio 2015 solution, your project.json should include :
"runtimes": {
"win10-x64": {},
"win7-x86": {} //IMPORTANT FOR AZURE DEPLOY
},
Or if you have already migrated to Visual Studio 2017, your .csproj should include this in PropertyGroup:
<RuntimeIdentifiers>win10-x64;win7-x86</RuntimeIdentifiers>
Also, your publish profile should include the same thing:
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<PublishProtocol>FileSystem</PublishProtocol>
<Configuration>Release</Configuration>
<TargetFramework>netcoreapp1.1</TargetFramework>
<PublishDir>bin\Release\PublishOutput</PublishDir>
<RuntimeIdentifier>win7-x86</RuntimeIdentifier> // IMPORTANT
</PropertyGroup>
</Project>
