Error MSB4062

Steps to reproduce

I have a lot old library projects(4.5.1) that builds correctly with new web site project. But one project that using some web references cannot be build from dotnet build with different configurations. For example dotnet build --configuration Debug normally executed but dotnet build --configuration Staging gives following error: Can someone help with this? Thanks

Actual behavior

C:\Program Files\dotnet\sdk\1.0.0\Microsoft.Common.CurrentVersion.targets(3344,5): error MSB4062: The “Microsoft.Build.Tasks.SGen” task could not be loaded from the assembly Microsoft.Build.Tasks.Core, Version=15.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. [D:\ep\ServiceLayer\ServiceLayer.csproj]

We have the save problem with build core project (release configuration and dotnet publish). Now it is working with msbuild.

msbuild %myPath%\MyProject.csproj /p:DeployOnBuild=true /p:Configuration=Release /p:PublishProfile=%myPath%\Properties\PublishProfiles\Release.pubxml /p:publishUrl=D:\Publish\MyProject
