Spring Cloud Configuration client for dotnet/c# - c#

I have a mixed technology stack and have an existing spring cloud config server set up. I also have dotnet/c# clients and I need them to work with the config server.
I was unable to find example dotnet code which understands the format and bootstraps at runtime. What I can do, worst case, is translate the server http response.
I see a lot of references to a steeltoe library but seems to be focussed on the server/provider.
Any ideas/example code?

This answer is a couple months late, but the Steeltoe Configuration library is a client for Spring Cloud Config Server, I think it is what you're looking for: https://steeltoe.io/docs/steeltoe-configuration/#2-0-config-server-provider
There are samples for ASP.NET 4.x and ASP.NET Core here: https://github.com/SteeltoeOSS/Samples/tree/master/Configuration/src

Alternative SignalR Redis implementation within Load Balancer Environment

We have completed a hybrid mobile application that makes use of SignalR (.Net Core) on the backend.
The issue we have now discovered is that, SignalR does not play nicely with load balancers and although there is Azure and Redis, to get this approved will be a nightmare.
Does anyone know of any alternative solution we can deploy without having to go to the architecture forum for approval of Redis.
Ideally, within C# WebApi and deploy to IIS.
NOTE! We cannot make use of Redis or Azure in our case.
Quick update: going to test this solution tomorrow. If we are successful, I will post an official answer.

Embedded C# web server with easy SSL support

I am looking for an embedded Web Server with out of the box SSL support, preferably configured from a command line or some easy config, without the need to change system wide config (like Registry). It should also work on mono.
Have you tried my old server http://webserver.codeplex.com? It supports SSL and at least used to run on MONO.
I'm also (slowly) building a new one, it got no SSL support yet (but's not that hard to implement by yourself): http://github.com/jgauffin/griffin.webserver
Edit
The HttpListener in Griffin.Framework have SSL support now
I recently came across two such packages.
ceenhttpd - https://github.com/kenkendk/ceenhttpd
and
uHttpSharp - https://github.com/Code-Sharp/uHttpSharp
The part i like about these is that both of them let you load a certificate file from disk. If you use the raw HtttpListener, that is a pain.
If you are open to use .NET Core, you can also self-host Kesterel. I plan to use this as soon as I convert my projects to .NET 5. here is a small sample code for that.

Subversion Protocol

I'm researching the feasiblity of building the ability to browse a subversion repository from my web app. I'm developing in asp.net. I've read some mentions of WebDAV, but nothing that seems particularly concrete. Does anyone know anything about the protocol that is used to communicate with SVN? Or even better, a .net library that can do so.
I think I may have answered my own question...
Edit: There is a new url:
http://sharpsvn.open.collab.net/
Subversion can serve repositories using 2 different protocols. The svn:// protocol is used by svnserve, the custom Subversion server. The http:// protocol is used by the Apache version of Subversion. Apache provides the webDAV functionality that you see with HTTP.
I created a library to work on the server part. It will do stuff like
Add and delete users
Change user's passwords
Create and delete repositories
Create and delete directories
It's called SVNManagerLib and I'm hosting it at CodePlex.
http://svnmanagerlib.codeplex.com
I've used it for a couple Winform apps, but I've also used it with WCF. It only works with svnserve configurations. I haven't had time to add Apache related functionality.

Is it possible to create a standalone, C# web service deployed as an EXE or Windows service?

Is it possible to create a C# EXE or Windows Service that can process Web Service requests? Obviously, some sort of embedded, probably limited, web server would have to be part of the EXE/service. The EXE/service would not have to rely on IIS being installed. Preferably, the embedded web service could handle HTTPS/SSL type connections.
The scenario is this: customer wants to install a small agent (a windows service) on their corporate machines. The agent would have two primary tasks: 1) monitor the system over time and gather certain pieces of data and 2) respond to web service requests (SOAP -v- REST is still be haggled about) for data gathering or system change purposes. The customer likes the idea of web service APIs so that any number of clients (in any language) can be written to tap into the various agents running on the corporate machines. They want the installation to be relatively painless (install .NET, some assemblies, a service, modify the Windows firewall, start the service) without requiring IIS to be installed and configured.
I know that I can do this with Delphi. But the customer would prefer to have this done in C# if possible.
Any suggestions?
Yes, it's possible, you may want to have a look at WCF and Self Hosting.
Yes, it is possible (and fairly easy).
Here is a CodeProject article showing how to make a basic HTTP server in C#. This could easily be put in a standalone EXE or service, and used as a web service.
One technology you might want to check out is WCF. WCF can be a bit of a pain to get into but there's a great screencast over at DNRTV by Keith Elder that shows how to get started with WCF in a very simple fashion.
http://www.dnrtv.com/default.aspx?showNum=135
You could take a look at HttpListener in the .Net framework.
I would highly recommend WCF. It would fit very well into a product like you are describing. There are a good number of books available.
Sure, you can do that. Be sure to change the Output Type of the project to Console Application. Then, in your Main function, add a string[] parameter. Off of some switch that you receive on the command line, you can branch to ServiceBase.Run to run as a Windows Service or branch to some other code to run a console application.
This question is somewhat older but since I needed something similar some time ago it felt like this question is still relevant.
I wrote a small Rest-API with NancyFx and OWIN. OWIN is a standard interface between .Net applications and web servers. With OWIN it is possible to create a self-hosted WEB-API. Nancy on the other hand is
a lightweight, low-ceremony, framework for building HTTP based
services on .NET ยน
The combination of those two makes it possible to create a self-hosted C# Web service.
I am quite sure that there are many more possibilities to create something like this by now but since I used it like this I thought the Information might be useful to someone.

Embedded Web Server in .NET

I would like to embed a light weight web server in a Windows application developed in .NET. The web server has to support PHP.
I have looked at Cassini, but it seems it is ASP.NET only.
The .net class HttpListener exposes the underlying http.sys upon which IIS is built. All machines since Windows XP2 have http.sys installed by default.
Here are some links to get you started.
XML-RPC SERVER USING HTTPLISTENER
HttpListener For Dummies
As for the PHP support, I don't know how you would enable this, but there is no technical reason you couldn't build it in.
I would look at the likes of XAMPP Lite which you could easily start up and shutdown with your application.
There is also AppWeb which claims to be exactly what you are looking for.
You can always use PHP as a CGI application. CGI is well documented, and AFAIK pretty easy to implement. Use Darrel Millers suggestion, and couple it with some CGI magick, and you should be cooking with gas.
Mongoose embedded webserver
https://code.google.com/p/mongoose/
You can build it with VS2012/10/08 as EXE and you can use PHP and also websockets to push data to the client app. Also you can build a DLL you can do this with make or bring the code into a VS DLL project and build out a _DLLMain, DEF file, etc. Then use it direct from C# - see the mongoose.cs and example.cs files.
