Azure Service Fabric missing DLL on production server: FabricCommon.dll


I have created an actor service, which runs on a development cluster. An ASP.NET application (hosted separately via IIS), connects to the cluster and uses the actors. This works fine.

But when I deploy everything to the production environment, the ASP.NET application fails to connect to the cluster with the below exception. The cluster is hosted on-premise (Windows 2012 R2).

The type initializer for 'Microsoft.ServiceFabric.Services.ServiceTrace' threw an exception.

It seems that the FabricCommon.dll could not be found on the web server (which hosts the ASP.NET).

I found that this file is part of the cluster installation package. On the development machine and cluster machines, the file is located here: C:\Program Files\Microsoft Service Fabric\bin\Fabric\Fabric.Code\FabricCommon.dll. But it is apparently not a dependency installed via NuGet in the client application.

Do I missed to install any prerequisites on the web server? Do I have to include the DLL manually?

Add the following Service Fabric bin path to your PATH environment variable:

set PATH=%PATH%;C:\Program Files\Microsoft Service Fabric\bin\Fabric\Fabric.Code 

Also set execution policy to unrestricted:

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Force -Scope CurrentUser

I think you need to install Service Fabric SDK on the web server.

See the link below:

I have this happen at one point in my dev machine. All I did was to reinstall the Service Fabric SDK.

For cases when you can't install Service Fabric SDK on target environment there is an option to use Service Fabric REST API.

Here is my repo with API client written in C# which can resolve service using this API

I had the same issue. Reboot my machine solved the issue.
