Service-fabric: IFabricSecretStoreClient Invalid cast exception thrown

[davebally]

Hi , ive updated the service fabric libraries from 6.3187 to 6.4.617 (as shown below) and am now getting the below exception thrown. This is when i try to instantiate a new FabricClient() object.

The code itself is in a .net standard library used within a .net core 2.2 application.
I have seen similar oddities where mixed versions are used but everything seems to be in line here.

Any clues ?!!?

Thanks

Have you updated the Cluster and SDK as well?

Not sure what the problem is in here, but the new libraries targeting an old cluster might cause these kind of issues.

@guibirow Seems to have been the issue, downloaded local SDK ( its a single node dev cluster ) and all now seems well.
