Answer 2

I was running 2.0.8, had to downgrade to 2.0.5 then it worked. The 2.0.8 didn't include a the Self-contained deployments (SCD) as supposed which 2.0.5 did.

I'm using VSTS to build and release

Answer 3

I had same problem publishing a simple spike app using VS2017 15.7.1 - File | New Project, ASP.NET Core Web App, MVC, ASP.NET Core 2.0 - Build and run on local host - Publish to Azure WebApp

Browser displayed error: HTTP Error 502.5 - Process Failure

Answer 4

After upgraded to ASP.NET Core 2.0, you need to add following configuration section to all the .csproj files in the solution.

<ItemGroup>
   <DotNetCliToolReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.0" />
</ItemGroup>

You could create a new ASP.NET Core 2.0 application to check it. The DotNetCliToolReference configuration section is already in the new ASP.NET Core 2.0 application project file but missed in your upgraded application project file.

Answer 5

With a bit of searching this worked for me.

Essentially clean out the wwwroot folder from a console on your Azure Portal. Make sure you get the top most wwwroot folder (I had a sub wwwroot folder for some reason.)

RD wwwroot /S /D

Should do the trick. Then just republish your site. It would appear that the publish process does NOT delete anything that already exists within the deploy folder. So you have 1.1 .dlls and 2.0 .dlls.

Hope that does the trick for you.
