Azure Web Deploy "Could not find a part of the path 'D:\home\site\wwwroot\bin\roslyn\csc.exe'."

Question

I've been browsing the web for a couple hours now looking for an answer to my problem. I am trying to deploy a Web API on Azure Web App Service using VS2017. Everything builds and works fine when running locally but once deployed on Azure (through VS2017) I get this error:

D:\home\site\wwwroot\bin\roslyn\csc.exe

My project is an ASP.NET Web Application (Using Azure Web API template) .NET Framework 4.6.1. I use Microsoft.CodeDom.Providers.DotNetCompilerPlatform Version=1.0.6.0

I also made sure that csc.exe is located in:

Visual Studio 2017\Projects\DeviceManagementAPI\DeviceManagementAPI\bin\roslyn

Answer 1

Just had the same problem and it seems it's a known issue with Microsoft.CodeDom.Providers.DotNetCompilerPlatform 1.0.6 and 1.0.7.

Downgrading to 1.0.5 solves the problem.

Answer 2

Upgrading Microsoft.CodeDom.Providers.DotNetCompilerPlatform to 1.08 worked for me
