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

Question

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?

Answer 1

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

Answer 2

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 

Answer 3

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

Answer 4

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