Cannot start with windows-host-process mode.

`ContainerAppCommand` default value is : `dotnet $(ContainerWorkingDirectory)$(TargetFileName)`. It should be `dotnet ./$(TargetFileName)`.

In windows-host-process mode, it shows /app/mydll.dll is not found.

Consider following yaml:

``` yaml
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: myapp
labels:
myapp
spec:
securityContext:
windowsOptions:
hostProcess: true
runAsUserName: "NT AUTHORITY\\Local service"
hostNetwork: true
containers:
- name: test
image: myaspnetapp:latest
workingDir: /hpc/app
env:
- name: PATH
value: C:/hpc/Program Files/dotnet
nodeSelector:
"kubernetes.io/os": windows

```

temp solution:

``` diff
apiVersion: apps/v1
kind: DaemonSet
metadata:
name: myapp
labels:
myapp
spec:
securityContext:
windowsOptions:
hostProcess: true
runAsUserName: "NT AUTHORITY\\Local service"
hostNetwork: true
containers:
- name: test
image: myaspnetapp:latest

+ command:
+ - dotnet ./myapp.dll
workingDir: /hpc/app
env:
- name: PATH
value: C:/hpc/Program Files/dotnet
nodeSelector:
"kubernetes.io/os": windows

```

Search the repository for the ContainerAppCommand default and inspect the code that assembles the container command. Verify the default uses dotnet ./$(TargetFileName), then run the relevant container-build or Windows host-process tests and confirm the application starts without the /app/mydll.dll error.
