"TransformWebConfig" task could not be loaded

We experience this error when building new VS2017 csproj project with msbuild 2015:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Sdks\Microsoft.NET.Sdk.Publish\build\netstandard1.0\TransformTargets\Microsoft.NET.Sdk.Publish.TransformFiles.targets(54,5): error MSB4062: The "TransformWebConfig" task could not be loaded from the assembly C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Sdks\Microsoft.NET.Sdk.Publish\build\netstandard1.0\..\..\tools\net46\\Microsoft.NET.Sdk.Publish.Tasks.dll. Could not load file or assembly 'file:///C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\Sdks\Microsoft.NET.Sdk.Publish\tools\net46\Microsoft.NET.Sdk.Publish.Tasks.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format. 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. 

Also it seems some other people experience it as well. See https://github.com/Microsoft/msbuild/issues/1010 and http://stackoverflow.com/q/42805862/213725

@night-king - The log shows that you have an incorrect configuration setup. You cannot have inprocess hosting with AspNetCoreModule.

Can you add this to the csproj? This should fix the issue.

<AspNetCoreModuleName>AspNetCoreModuleV2</AspNetCoreModuleName>

It may be the same reason for a special case, but same is true for Service Fabric’s *.sfproj projects.
