Publish failed when using Microsoft.NET.Sdk.Razor if reference was not recognized, but build works

Question

The problem

I've upgraded my solution from asp.net core 2.0 web app to 2.1 and in one of my class libraries I'm using 'Microsoft.NET.Sdk.Razor' SDK.

• Rebuilding the solution from VS works
• Publishing the web project from command line using 'dotnet publish' works
• Publishing the web project from VS fails. The error output suggests that some of my project in solution is not included when publishingthe library with razor views.
• When I remove Microsoft.NET.Sdk.Razor and use just 'Microsoft.NET.Sdk' publishing from VS works.

Solution projects:

• MyProject.DataAccess.csproj (netstandard2.0, nuget refereces Microsoft.EntityFrameworkCore.SqlServer 2.1)
• MyProject.Mail.csproj (netcoreapp2.1, Microsoft.NET.Sdk.Razor, references MyProject.DataAccess.csproj)
• MyProject.Shared.csproj (netcoreapp2.1, Microsoft.NET.Sdk, references MyProject.DataAccess.csproj)
• MyProject.Web.csproj (netcoreapp2.1, Microsoft.NET.Sdk.Web, references MyProject.Mail.csproj and MyProject.Shared.csproj, nuget reference Microsoft.AspNetCore.App);

The log file says:

System.AggregateException: One or more errors occurred. ---> System.Exception: Build failed. Check the Output window for more details. --- End of inner exception stack trace --- at System.Threading.Tasks.Task.ThrowIfExceptional(Boolean includeTaskCanceledExceptions) at System.Threading.Tasks.Task.Wait(Int32 millisecondsTimeout, CancellationToken cancellationToken) at Microsoft.VisualStudio.Web.Publish.PublishService.VsWebProjectPublish.<>c__DisplayClass41_0.b__2() at System.Threading.Tasks.Task`1.InnerInvoke() at System.Threading.Tasks.Task.Execute() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.VisualStudio.ApplicationCapabilities.Publish.ViewModel.ProfileSelectorViewModel.d__116.MoveNext() ---> (Inner Exception #0) System.Exception: Build failed.

Answer 1

For my case, I have installed Microsoft.NET.Sdk.Razor 2.2.0

Open "Package Manager Console" run follows query....

Install-Package Microsoft.NET.Sdk.Razor -Version 2.2.0

Razor is a markup syntax for adding server-side logic to web pages. This package contains MSBuild support for Razor.

Answer 2

It's a bug. Fix should be available in the upcoming SDK version 2.1.1. There are 3 things you can do right now:

1. You can install SDK 2.1.301 (x64 Installer, x86 Installer, Version info)

2. Or you can make the fix yourself for current 2.1.300 SDK, it's a one liner in C:\Program Files\dotnet\sdk\2.1.300\Sdks\Microsoft.NET.Sdk.Razor\build\netstandard2.0\Sdk.Razor.CurrentVersion.targets and change line 460 from:

   DependsOnTargets="RazorCompile"
   

   to

   DependsOnTargets="ResolveRazorGenerateInputs"
   

3. Or keep using dotnet publish
