Azure App Service doesn't run after upgrading to DotNet Core 2.2

Question

After the release of DotNet Core 2.2 I upgraded my Solution to the new version but when I deploy it to my Azure App Service, it no longer runs. It simply gives the following error: The page cannot be displayed because an internal server error has occurred.

My .csproj file looks like this in case you'd need it:

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <DockerDefaultTargetOS>Linux</DockerDefaultTargetOS>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="2.2.0" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.0.2105168" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.2.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\DAL\DAL.csproj" />
    <ProjectReference Include="..\Model\Models.csproj" />
  </ItemGroup>

  <ItemGroup>
    <WCFMetadata Include="Connected Services" />
  </ItemGroup>

  <ItemGroup>
    <Folder Include="wwwroot\userPictures\" />
  </ItemGroup>

</Project>

Answer 1

It seems that asp.net core 2.2 updates have not fully rolled out to all regions for Azure App Services. See: https://blogs.msdn.microsoft.com/webdev/2018/12/04/asp-net-core-2-2-available-today/

They say it will be rolled out over the coming weeks and finished by the end of December.

It seems there is some sort of workaround, although I don't know the specifics: https://github.com/dotnet/core/blob/master/release-notes/2.2/2.2-known-issues.md

Answer 2

I noticed that nuget updated web.config by changing AspNetCoreHosting to AspNetCoreHostingV2. I reverted to AspNetCoreHosting and the app came straight back online. Looks like this will be fixed by end of the year according to links in answer from @Dan.

for the record I'm using net472 not netcoreapp2.2
