Hi, I have a project (Service Fabric if that matters) which uses a custom props and targets files which call a DLL winch has a dependency on Newtonsoft.Json.dll which is shipped alongside. When I build inside VS2017 I have no errors. But when I run dotnet build I’m getting this:

BuildLayout.targets(21,5): error MSB4018: The “GenerateArmTemplateTask” task failed unexpectedly. [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: System.IO.FileLoadException: Could not load file or assembly ‘Newtonsoft.Json, Version=11.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed’. Could not find or load a specific file. (Exception from HRESULT: 0x80131621) [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: File name: ‘Newtonsoft.Json, Version=11.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed’ [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: at BuildLayout.Generators.TemplateGenerator.Generate(BuildLayoutOptions args, ApplicationManifestType appManifest) [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: at BuildLayout.Generators.BuildLayoutGenerator.Generate(BuildLayoutOptions args) in e:\bt\921388\repo\src\product\buildlayout\Generators\BuildLayoutGenerator.cs:line 23 [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: at BuildLayout.Tasks.GenerateArmTemplateTask.Execute() in e:\bt\921388\repo\src\product\buildlayout\Tasks\GenerateArmTemplateTask.cs:line 46 [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(ITaskExecutionHost taskExecutionHost, TaskLoggingContext taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask) [DeploymentAgent.sfproj] BuildLayout.targets(21,5): error MSB4018: [DeploymentAgent.sfproj]

Please help me to understand how it works and why i’m getting it.

Ping.

I think the source of confusing was that AssemblyVersion for all releases in 11.x.x is 11.0.0. Give it a try and please let me know.

I’m seeing the same error when running dotnet build from the cli after adding the Mobile.BuildTools package. It has a dependency on Newtonsoft.Json 11.0.2

/Users/username/.nuget/packages/mobile.buildtools/1.4.0.638/build/Mobile.BuildTools.targets(56,5): error : Could not load file or assembly 'Newtonsoft.Json, Version=11.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'. Could not find or load a specific file. (Exception from HRESULT: 0x80131621) [/Users/username/Projects/DotNetBuildErrorExample/DotNetBuildErrorExample/DotNetBuildErrorExample.csproj]

Build FAILED.

I’m not sure why it’s trying to find 11.0.0.0 since that isn’t what the package is requiring.

I’ve added a repro repo If you try and build the project from the cli you’ll see the error.
