gRPC StarLink Router .Net

New Info:
I thought I would paste this in full as I can not seem to find any samples on the web of a c# solution for StarLink so hopefully anyone else looking for something may find this helpful and may contribute.
My New Proto File - (partial) - I took the advise of Yuri below. Thanks for the direction here. I was able to I have been using this tool and it has brought a lot of insight but I am still stuck on the c# side of the solution. I am an old VB.Net developer though I have done a bunch in c# I am by no means savvy in it and am probably missing something so simple. Again, any insight would be awesome. I can not post the full proto here as stack has char limit on posts. this is the first bit with messages etc. I can post more if it helps but trying to keep it to the important part.

My New .cs
I have tried many things from Microsoft's examples to thing I can gather from other samples. I simply can not get it to work and am lost. Again, any insight would be amazing and hopefully helpful to others looking for a solution in c#. You will see my commented code of this I have been playing with. Basically I am attempting to achieve three things and have made some movement in one of them.
Goals:
1 - Use Server Reflection to discover services.
I think I got this one resolved with dot-net grpc.
2 - Simply want to check available methods under a service and potentially either check or generate a new .proto file in case things change. StaLink does not publish its proto schema so I assume it could change anytime without warning.
3 - Just run any one of the available methods. I have tried the GetDeviceInfoRequest but can not seem to construct the request message properly. I have not been able to get this accomplishe in the gRPCurl tool either. I can do it on the basic service shown by Microsoft of course but these methods seem to be more complex and I simply get all kinds of errors.
Again, any insight or assistance would be amazing. Thanks to any and all in advance.

Apache Ignite .Net GetDataStreamer WithExpiryPolicy

var cache = client.GetOrCreateCache<int, int>("test").WithExpiryPolicy(new ExpiryPolicy(TimeSpan.FromSeconds(5), null, null));
using (var ldr = client.GetDataStreamer<int, int>("test"))
{
for (int i = 0; i < 20; i++)
ldr.AddData(i, i);
ldr.Flush();
}
I set the WithExpiryPolicy, but the data added by GetDataStreamer does not expire. Please tell me how to set the data to expire.

WithExpiryPolicy does not modify the underlying cache itself. Instead, it returns a new instance with the specified policies. This allows you to configure different policies on the same cache depending on some business logic.
At the same time, the DataStreamer is looking for a cache as it was created and doesn't care about WithExpiryPolicy. I'd suggest you configure the cache explicitly and re-run your example with the following configuration:
var cacheConfiguration = new CacheConfiguration
{
Name = name,
ExpiryPolicyFactory = new ExpiryPolicyFactory(
new ExpiryPolicy(TimeSpan.FromSeconds(1), null, null))
};

Could not load type 'SAS.LanguageServiceCarriageControl' from assembly

In addition to using the integration components of SAS Enterprise Edition, I am using parts of the following project I found on Github to connect with a SAS server. The goal here is to command the server to run programs on a schedule. However, the programs need to be modified each time, which is why I am attempting to trigger them to run in this manner. However, it keeps throwing an error at lang.FlushLogLines.
https://github.com/cjdinger/SasHarness
SAS.Workspace ws = server.Workspace;
List<string> results = new List<string>();
Array CCs;
Array lineTypes;
Array logLines;
int maxLines = 100;
SAS.LanguageService lang = (SAS.LanguageService)ws.LanguageService;
Array linesVar = (Array)new string[] { PROGRAM_TEXT };
lang.SubmitLines(ref linesVar);
//THROWS AN ERROR HERE
lang.FlushLogLines(maxLines, out CCs, out lineTypes, out logLines);
for (int i = 0; i < logLines.Length; i++)
{
results.Add((string)logLines.GetValue(i));
}
After a bit of research I found the following thread where it is recommended to make sure that all the required dlls are referenced in my project. The mystery here is that I do have them referenced, but the error still occurs.
http://blogs.sas.com/content/sasdummy/2013/06/09/sas-client-with-microsoft-dot-net/
Moreover, starting after the very first line, the code is no longer using SASHarness, but is using native SAS integration libraries only. The code above is also based on examples listed in the following documentation from SAS.
https://support.sas.com/documentation/cdl/en/itechwcdg/61500/PDF/default/itechwcdg.pdf (page 27-28)
Has anybody encountered an error similar to this, and if so, how did you correct it?

Strangely, fixing this error required declaring an instance for each of the assemblies that could not be loaded. I have no idea why this fixes the problem, but it works now.
SAS.Workspace ws = server.Workspace;
string wsId = ws.UniqueIdentifier;
List<string> results = new List<string>();
Array CCs;
Array lineTypes;
Array logLines;
int maxLines = 100;
SAS.LanguageService lang = (SAS.LanguageService) server.Workspace.LanguageService;
Array linesVar = (Array) new string[] { PROGRAM_TEXT };
lang.SubmitLines(ref linesVar);
//For some reason, these two declarations need to be here
SAS.LanguageServiceCarriageControl CarriageControl = new SAS.LanguageServiceCarriageControl();
SAS.LanguageServiceLineType LineType = new SAS.LanguageServiceLineType();
lang.FlushLogLines(maxLines, out CCs, out lineTypes, out logLines);
for (int i = 0; i < logLines.Length; i++)
{
results.Add((string) logLines.GetValue(i));
}

Using C#, how do I determine if an uploaded file has any accessible metadata/document properties?

Suppose I have a program which allows a user to upload any kind of file. Along with getting generic information such as file type and file size, I would like to attempt to grab any extra information (such as document properties like author, last revised, etc) that may be transported along with the document.
Since I don't have any knowledge about the incoming document/file ahead of time, I can't simply use classes that are specific to, say Microsoft Office docs. I need to do this generically and then construct a dynamic object or dictionary to hold any found key/value results.
Is this possible? If so, how? Any help is appreciated!

I found a few answers on StackOverflow for this, but none gave me a nice, clean dictionary of document properties. Here is what I finally came up with and it seems to be working nicely (you will need to reference "Microsoft Shell Controls and Automation" from the COM folder and add using Shell32; to your code:
public static Dictionary<string,string> GetDocumentMetadata(string fileName)
{
var properties = new Dictionary<string,string>();
var arrHeaders = new List<string>();
var shell = new Shell();
var objFolder = shell.NameSpace(HttpContext.Current.Server.MapPath("~/RawFiles"));
var file = objFolder.ParseName(fileName);
for (var i = 0; i < short.MaxValue; i++)
{
var header = objFolder.GetDetailsOf(null, i);
if (String.IsNullOrEmpty(header))
break;
arrHeaders.Add(header);
}
for (var i = 0; i < arrHeaders.Count; i++)
{
var value = objFolder.GetDetailsOf(file, i);
if (!String.IsNullOrEmpty(value))
{
properties.Add(arrHeaders[i], value);
}
}
return properties;
}

Is There a Settings Viewer/Manager for Windows 8 apps?

For testing my roaming and/or local settings, I'd like to be able to clear all the settings.
I could do it like so, I guess:
App.roamingSettings.Value["SomeVal"] = string.Empty;
App.roamingSettings.Value["SomeOtherVal"] = string.Empty;
App.roamingSettings.Value["YetAnotherVal"] = string.Empty;
...
etc.
...but I'd rather have some quicker, cleaner (no pun intended) way. Is there one?
Also, relatedly, it would be nice to have a "Settings Manager" utility for quickly verifying they are what you think they are, too. Does anybody know of one?
UPDATE
This is my attempt to "roll my own" based on the answer; so far, no go:
string roamingSettingPairs = string.Empty;
for (int i = 0; i < App.roamingSettings.Values.Count; i++)
{
// Print out whatever you want to verify that everything is as it should be
//string roamingSettingName = App.roamingSettings.Name[i].ToString();
//string roamingSettingValue = App.roamingSettings.Values[i].ToString();
Dictionary<string, object> roamingSettingVals = App.roamingSettings.Values;
string roamingSettingName = roamingSettingVals.Keys[i];
object roamingSettingObj = roamingSettingVals.Values[i];
//roamingSettingPairs = string.Format("{0}{1}={2}{3}", roamingSettingPairs, roamingSettingName,
// roamingSettingValue, Environment.NewLine);
}

You can delete all of your roaming settings using this code:
ApplicationData.Current.RoamingSettings.Values.Clear();
For a Settings Manager, I would probably just use a for loop like so:
for (int i = 0; i < ApplicationData.Current.RoamingSettings.Values.Count; i++)
{
// Print out whatever you want to verify that everything is as it should be
}
