ASP.NET CORE 2.1 Preview "SharedCompilationId" parameter is not supported by the "Csc" task

Question

I am trying run the project with views in separate class library on Mac OSX as described in below article

https://blogs.msdn.microsoft.com/webdev/2018/03/01/asp-net-core-2-1-razor-ui-in-class-libraries/

The problem is that I cannot build the class library project with Visual Studio Community 7.4 on Mac OS.

Project builds with command line (donet build) without problems but when I try to build it with Visual Studio it throws two errors:

/usr/local/share/dotnet/sdk/NuGetFallbackFolder/microsoft.aspnetcore.razor.design/2.1.0-preview1-final/build/netstandard2.0/Microsoft.AspNetCore.Razor.Design.Compilation.targets(10,10): Error MSB4064: The "SharedCompilationId" parameter is not supported by the "Csc" task. Verify the parameter exists on the task, and it is a settable public instance property. (MSB4064)

/usr/local/share/dotnet/sdk/NuGetFallbackFolder/microsoft.aspnetcore.razor.design/2.1.0-preview1-final/build/netstandard2.0/Microsoft.AspNetCore.Razor.Design.Compilation.targets(5,5): Error MSB4063: The "Csc" task could not be initialized with its input parameters. (MSB4063)

When I change RazorCompileOnBuild to false or remove Content from Content Build project compiles without errors.

Answer 1

Go to Nuget Console and add:

Install-Package Microsoft.Net.Compilers -Version 2.8.2

You will no longer get above mentioned error.

Answer 2

I had this problem on the build server but not locally.

The solution: Install the updated Visual Studio on the build server. In my case 2017.15.4

Answer 3

As I find you can solve this issue in two ways.

Solution 1

Add Microsoft.Net.Compilers compilers package to the project.

Solution 2

Build the project using the command line. dotnet build

Answer 4

In my case, I had installed the .NET Core 2.1 SDK, but not the runtime.

Strange how Microsoft don't include the runtime in the SDK.
