Publish website without roslyn

Question

I am trying to create web application using Visual Studio 2015 and .NET 4.5.1. When I publish the website, visual studio create folder named roslyn.

I know it's used to compile code on the fly, but unfortunately my hosting provider doesn't allow me to execute the compiler on their server.

How to publish the website without roslyn like previous version of Visual Studio?

EDIT: I got this error when trying to acces my website.

It seems IIS trying to execute roslyn\csc.exe but my user account doesn't have permission to do that. With previous version of Visual Studio, this error doesn't show up.

Answer 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".

Answer 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

Answer 3

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

Answer 4

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.

Answer 6

I have had the same issue in Sept2016 when I took over an existing ASP.NET program. I found that there were multiple versions of the two compiler packages mentioned by Kemal installed in different projects of the solution.

So firstly I updated to get them the same. VS doesn't tell you that updates are available in this scenario (or maybe I missed them ?)

I then had to restart VS2015 for the packages to clean up properly.
