.NET Windows Service - Architectural Decisions

I hope this helps you . Your description sounds a lot like the thing I wrote about 2 years ago. A windows service which hosts addins and runs them in multithreaded environment. The architecture used is the .NET addin pipeline introduced in .NET 3.5 (System.AddIn-namespace). It works like a charm as I also integrated live/hot updates. It's so easy to implement new addins and just plug them in whenever I like. So I really recommend using this addin stuff.
See http://msdn.microsoft.com/en-us/library/cc175292.aspx for a quickstart.

Accessing Istio enabled K8S pod from a service outside of the mesh

it fixes the issue If you have auth (mTLS) enabled it doesn't work, by design, as in that case Istio tries to protect all service to service communication.
You can turn auth off, and if that doesn't help, also try with the Istio 0.2.4 release candidate (or whichever is the latest at the time you read this, see https://github.com/istio/istio/releases) and see if the problem persists, if it does please file an issue at https://github.com/istio/issues/issues/new

How to host multiple applications in one Istio service mesh?

To fix this issue On what path your Hasura's GraphQL endpoint is configured?
The way your VirtualService is configured, a request to your gateway will behave like this:
code :
- match:
  - uri:
      prefix: /hasura1
    uri: /
  - destination:
      host: hasura-1
        number: 80

How to upgrade Istio Service Mesh from http to http2?

seems to work fine Based on my knowledge, istio documentation and istio feature stages(http2 in stable phase)
code :
apiVersion: networking.istio.io/v1alpha3
kind: Gateway
  name: my-ingress
    app: my-ingress-gateway
  - port:
      number: 80
      name: **http2**
      protocol: **HTTP2**
    - "*"
kind: Service
  name: myservice
  - number: 80
    name: http2

Service Mesh( like Istio) vs Even Driven Architecture of microservices

fixed the issue. Will look into that further You are mixing up several things.
Istio, linkerd etc. addresses some of the fundamental design/architecture issues which come up with cloud native, containerised microservices. e.g. service discovery, circuit breakers etc. Those concerns used to be addressed using libraries which are embedded within application like Spring cloud, hystrix, ribbon etc. Service meshes solve this problem within the paradigm of container world.
