Visual Studio 2015 Build errors - The "Csc" task could not be initialized with its input parameters

Question

Visual Studio 2015 Build errors:- The "Csc" task could not be initialized with its input parameters. The "Features" parameter is not supported by the "Csc" task.

Can anyone tell me why I can't build a new empty or otherwise project or build an existing old project without first editing my .csproj file?

In a new project I have found that if I move the 5th line

<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />

up to the 3rd line save, reload and then build all is good.

In old projects I have to add the same line to the same place prior to building.

Once this is done all seam ok from now on!

Answer 1

I have encountered the same issue. In my case, I got a duplicate Microsoft.CodeDom.Providers.DotNetCompilerPlatform and Microsoft.Net.Compilers in my .csproj. Deleting the duplicate (the lower version) was the solution for me. It was also due to copy-paste of nuget packages from packages.config and re-installing it.

Answer 2

I don't know what the hell was that but after installing:

Install-Package Microsoft.Net.Compilers -Version 2.9.0

Everything start working.
