Publish website without roslyn

Solution 1:

I've just faced the same problem. When you create a new web project, two nuget packages automatically added to your project. If you remove them, your problem should be solved. Package names are: "Microsoft.CodeDom.Providers.DotNetCompilerPlatform" and "Microsoft.Net.Compilers".

Solution 2:

I had the same issue. Followed the steps from here. Basically:

1. Uninstall the package

   Uninstall-package Microsoft.CodeDom.Providers.DotNetCompilerPlatform <Your Web API project name>
   

2. In your publish profile settings, uncheck "Allow precompiled site to be updatable". You can find this under Settings > Precompile during publishing > configure

Solution 3:

After searching the same issued I face, I just came here. I read the above answer which is right.

I give the answer, because of Here is the good article to explain :

1. Why the publish code have this exe as well as development environment ?
2. What is the benefit and how to remove?

This is also the very good article, about the history of this exe

Solution 4:

After countless effort....and according to this website. I find that you can use /p:UseWPP_CopyWebApplication=true /p:PipelineDependsOnBuild=false in MSBuild to transform web.config, this also include the roslyn compiler in the build. The output is same as what you get by publishing in Visual Studio into file system

Solution 5:

There is an open bug on the roslyn repository about this issue.

In my case all I had to do was to downgrade the dll Microsoft.CodeDom.Providers.DotNetCompilerPlatform from version 1.0.6 to 1.0.5.
