ServiceFabric RemotingTransport settings in ASPNET Core project

When wirting a Service Fabric Service that uses the Remoting Transport layer, you sometimes need to update the default settings to allow for a greater message size or operation timeout.

According to the documentation, this is achieved by overriding the default settings in the Assembly manifest file that you find under Properties/AssemblyInfo.cs

using Microsoft.ServiceFabric.Services.Remoting.FabricTransport;
// Allow messages up to 100 MB, operation timeout to 10m
[assembly: FabricTransportServiceRemotingProvider(MaxMessageSize = 100000000, OperationTimeoutInSeconds = 6000)]

However, you might notice that if you created an ASPNET Core service (to use as a gateway perhaps), the new project type does not have the AssemblyInfo.cs file anymore. Even more, if you create it yourself, it will be ignored.

This is happening because in the new ASPNET CORE project type, the AssemblyInfo file is auto-generated during build. Since there’s no other way (as far as I could find) to update our remoting settings, we need to get rid of the auto-generated file and write our own.

First, create your own AssemblyInfo.cs file under the Properties folder.
Next, find the auto-generated file in the obj folder. Copy its contents over into your newly created file.
Lastly, we need to instruct the build system to not generate the file automatically any more.
We do this by updating the project file:


That’s it, with these changes, you now have the new remoting settings available for your ASPNET CORE project.
