.net-core-2.0 azure app service 502.5 error

Getting a 502.5 error after CI deployment to azure app service.

When running dotnet {myproject}.dll on the debug console this is the error I get:

Unhandled Exception: System.IO.FileLoadException: Could not load file or assembly 'System.Diagnostics.DiagnosticSource, Version=4.0.2.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) at Microsoft.AspNetCore.Hosting.WebHostBuilder.BuildCommonServices(AggregateException& hostingStartupErrors) at Microsoft.AspNetCore.Hosting.WebHostBuilder.Build() at My.IOEducation.Api.Program.Main(String[] args) in D:\home\site\repository\My.IOEducation.Api\Program.cs:line 11

Running dotnet --version returns 2.0.0

Anyone else run into this yet and any suggestions on how to resolve?

UPDATE: Here is the contents of the project file.

I spoke to the aspnet IISIntegration team members and found my solution.

tldr: Empty out your wwwroot folder on kudu.

The issue relates to having old things leftover from previous 1.x deployments

Step 1:

Navigate to the Kudu Console (https://{yourapp}.scm.azurewebsites.net/)

Step 2:

Step 3:

(Note: navigate into the "site" directory)

(Note: there is a wwwroot folder within this wwwroot. You should delete the one that is in the "site" directory)

Step 4:

Add a new empty folder called wwwroot where you just deleted the previous one (within "site" directory)

(Note: my deployment failed when I didn't have the empty wwwroot folder in there)

Step 5: Redeploy your app and hopefully it works. Good luck
