ASP.NET Core 2.1 Preview 2 App Not working on Azure App Service

Question

I've been running my ASP.NET Core 2.1 Preview-1 app on Azure since this release became available. I had installed the ASP.NET Core runtime extensions through the portal and it's been working fine.

Now that Microsoft released ASP.NET Core 2.1 Preview-2, I installed the upgrade to the SDK. Updated my Nuget packages so that I have the preview-2 versions of everything. See my csproj file below:

I also removed the ASP.NET Core Runtime extensions from Azure App Service for my app which was showing 2.1 Preview-1. Instead installed ASP.NET Core 2.1 run times for x86 and x64 separately -- see below:

Compiled the app and published it to my Azure App service but I'm getting errors. First I got the 502.5 error. Now, I'm getting:

The specified CGI application encountered an error and the server terminated the process.

What am I missing here?

UPDATE:

As the answer suggested, I set my target to x86 (to play it safe) -- see below:

I removed the extension and the individual x86 and x64 run times and installed only the x86 with support for ASP.NET Core 2.1 preview-2 -- see below:

I restarted the app several times and I'm still getting 502.5.

I then tried to do a self deploy through CLI command line by issuing the following command:

dotnet publish -c Release -r win10-x64

And I get the following error:

C:\Program Files\dotnet\sdk\2.1.300-preview2-008530\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.RuntimeIdentifierInference.targets(125,5): error : The RuntimeIdentifier platform 'win10-x64' and the PlatformTarget 'x86' must be compatible.

Does this mean I have the x86 version of the SDK installed and I must target x86?

I didn't have half the trouble that I'm going through now going from ASP.NET Core 2.0 to 2.1!!!!

UPDATE 2: Just ran dotnet --info in Kudu console. If I'm reading this correctly, I don't have the correct runtime.

Update 3:

I think this screen shot confirms what I was saying.

Update 4:

I installed x86 version of ASP.NET Core 2.1 Runtime -- see below:

When I run dotnet --info in Kudu console, I get the following which confuses me. I'm still not seeing the version I was expecting to see:

And when I hit the URL, I'm still getting 502.5 and the same message in Kudu console when I run dotnet MyApp.dll telling me that the correct version of the runtime is not found.

How will I get the correct version in there? I thought installing it through the portal would do it.

We've managed to publish ASP.NET Core 2.1 RC1 webapp to Azure app-service using "self-contained" deployment mode.

Platform target: Any CPU

Here are the package references from our .csproj:

<PackageReference Include="Microsoft.AspNetCore.App" /> <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1.0-rc1-final" PrivateAssets="All" /> <PackageReference Include="Microsoft.AspNetCore.AzureAppServicesIntegration" Version="2.1.0-rc1-final" />
