How to solve open id configuration error with identity server 4?

I am trying to use Identity Server 4 for Authenticationa and authorization purpose but which ever project i try to run is throwing only 1 error which is like bugging me alot because i have search for this error and i cant find a stable and proper solution for this.
Error :
Error connecting to
http://localhost:5000/.well-known/openid-configuration: An error
occurred while sending the request.
Couple of projects in which i am getting same error and dont know how to solve it :
https://www.dropbox.com/s/9hs3huwt8h035ek/oauth2Demo-master.rar?dl=0
Another Project : Download but same error
In my first project it seems like there is some problem related to SSL certificate though i tried to follow below link to install certificate but still this error exist :
https://github.com/IdentityServer/IdentityServer3.Samples/tree/master/source/Certificates
But in my second project there is no such SSL certificate problem but still same error.
Is there any way to resolve that error?

I downloaded the solution and I can confirm you need to make sure to run the OAuth2Demo.IdentityServer project, you can actually start it up and navigate to https://localhost:44305/admin/ to see the admin environment of identityserver. It apperantly also needs a sql connection to store configuration information, I didn't dig into those details but with the OAuth2Demo.IdentityServer running the other projects can also be started.

My suggestion is to get the things done one by one.
From your screens I see that on the first you are trying to reach IDS at localhost:44305, and on the second screen, you are trying to reach it at localhost:5000. It will be a good thing to set it as a constant value ( right click on your Identity Server project ->Properties->Debug->Web Server Settings->App URL) and then use this value through all of your clients.
Then - enable Identity Server logging - check here. You can extend this example - serilog basic configurations. So far logging has saved me many times, so I can say that it is really important. Make sure that the App pool account, running the application has the rights to create files, where you want them to be created.
Now the real problem:
Lets assume that you select localhost:5000 as url for your IDS.
First of all start (debug) only the Identity Server project. This should take you to localhost:5000 and you will see a welcome message from Identity Server 4.
If you see it, this means that your IDS is working. This also means that you will be able to access the Discovery Document - the one thing that is failing in your clients. Now its about time to setup your clients.
If not, this means that there is something wrong with your Identity Server instance, and that is the place to dig.
First thing I'll do is to check the logs. They will say what the problem is.
Then - I figure out that you are trying to use custom certificate for this (correct me if I've misunderstood). Why don't you try using the Developer Signing Credential (check the ConfigureServices of Startup.cs) at least for starting it up.
Later on, if you decide to use your custom certificate, have in mind that the user, that is running the IDS application (by user I mean the application pool user) should have at least read privileges over the certificate (I guess that you've seen that in the article you have provided).
Do all these, and let's see what progress you will have, but most important - enable the logging.

DNN Database Repository Reuse in Console Application

I have a project based on the Chris Hammond, Christoc, module template. I have a ton of code that I use to access data an external database. In my repositories I change the database from the default to whichever I need for that particular object. I do so with code that looks like this:
using (IDataContext ctx = DataContext.Instance(MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY))
{
var rep = ctx.GetRepository<Product>();
products = rep.Get().ToList();
}
The default database is switched in the call to .Instance(). The repositories are used by my custom DNN modules. The repository is part of the solution that contains multiple custom modules. When I compile and install using the Extensions part of DNN, everything works well. In the code above, MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY is found in a file MyModuleSettingsBase.cs file of my module solution. It is set to a simple string like "ProductDatabase". In the solution for the base DNN install (not the module solution), within the web.config file, there is a value in <connectionStrings> with name="ProductDatabase" which contains the actual connection string. This all links up fine on the DNN website.
Now I am writing a console application that does some monitoring of the site. I want to access the database to check values in the product table. I would like to reuse all of the repository code I have written. In an attempt to do so, I added a reference to the MyModules.dll file so I would only have one copy of the base code. This works to give me access to all the objects and the associated repositories but when I attempt to query data it fails. When debugging I can see that it fails on the line:
using (IDataContext ctx = DataContext.Instance(MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY))
When viewed in a debugger, the string value MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY is correctly set to "ProductDatabase" but the code is unable to link this with the actual connection string. I don't know where it would be checking for the connections string when running from my console application. I attempted to put a <connectionStrings> section into my App.config file but this didn't do the trick.
Is it possible to have MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY map to the connection string in an external application which references the DLL?
If so, where can I set the value of my connection string so it matches up to the key value stored in MyModuleSettingsBase.DATABASE_CONNECTION_STRING_KEY?

I was faced similar problem 3 months ago, at that time I want to use DNN core libraries in my console application but I was failed.
I placed my queries in DNN official forum website and I got a valid response from Wes Tatters (DNN MVP).
Here is the post link: Reference URL
As your requirement of monitoring, I suggest you to create DNN Schedule Application. You can schedule it within DNN (Host->AdvancedSettings->Schedule), even good point is that you can use your repositories (DNN Libraries) in that schedule application.
I hope it solved your problem. Let me know if you have any questions.

microsoft.identitymodel.clients - cannot find this

I'm trying to use azure acs and the windows live, google etc. identity providers as highlighted in this walkthrough
however I am having the problem with the piece of code
AuthenticationContext _authContext = new AuthenticationContext("https://{your ACS
namespace}.accesscontrol.windows.net");
AssertionCredential theToken =
_authContext.AcquireUserCredentialUsingUI("urn:WPFWithAAL");
which returns an error that the type or namespace AssertionCredential cannot be found. I found this which suggest it exists in the Microsoft.IdentityModel.Clients.ActiveDirectory namespace, but i can't add this namespace because there doesn't seem to be a Microsoft.IdentityModel.Clients namespace that i can add.
Also, when i build the application, it actually returns a slightly different error in the output, saying Microsoft.WindowsAzure.ActiveDirectory.Authentication.AssertionCredential is inaccessible due to its protection level. so i am unsure what the actual error really is and how to resolve it.
i am building a WPF 4.5 Desktop Application, that will require authentication and will need to link to "social" accounts such as windows live / google etc. so i need a way to do this. if this is not the way forward, can anyone suggest an alternative method?

Google-drive example: oauth2callback not found

I need a little help with the C# example program of Google-Drive...
I used this so-called "tutorial"/"example":
https://developers.google.com/drive/examples/dotnet
And the code from here:
https://code.google.com/p/google-drive-sdk-samples/source/checkout
I uploaded my (only slightly modified) sourcecode here in case anybody doesn't have Mercurial (I didn't have Mercurial and no admin rights to install it either, and Mercurial is the only way to get the sourcecode...):
http://verzend.be/elt0k13enraw/DrEdit.rar.html
I always get
"Ressource cannot be found"
Requested URL: /oauth2callback
I don't find this astonishing, as no oauth2callback controller or handler is implemented...
I tried adding a Controller called oauth2callbackController and redirecting to another action in oauth2callbackController.Index, doing
return new RedirectResult("/about/about");
But that only creates a NULL-reference exception.
So i figured, maybe the wrong controller and redirected to
return new RedirectResult("/drive/Index");
But that only creates an infinite loop of redirect -> allow -> redirect - allow -> etc.
BTW, the config to change the API key + REDIRECT_URI is in
Models\ClientCredentials.cs
Note:
The problem aren't my modifications.
The sample also didn't work unmodified, with the exact same error.
All I did was removing EntityFramwork references, and throwing "Not implemented exception" when a method using entity was called.
Edit:
Additional information:
What I really wanted to do in the first place is to write a console service that exports my database, LZMA-compresses the exported content, encrypts that with OpenPGP, and uploads the database of my server to Google drive every day at 24:00 o'clock, without any user input.
I got export working without a problem, i got the LZMA compression working without a problem, I got the encryption with PGP working without a problem.
After the end of the working day (grrrr), when I was at home, I was even able to download the example-code with the mercurial installed on my Linux-machine at home, and bring it on the windows machine using SMB...
But now I can't get the sample for the Google-drive SDK working...
And moreover, what I really need is an example for a console service/daemon, not a web-application.
When I created the API key, I saw one could create a key for a service, but there is no example on how to write a Google-Drive service (console application), and no useful documentation as well (yea there is a reference, but it's only a reference, IntelliSense provides about the same)...

When configuring your app in the API Access tab of the APIs Console, you had to set the root (/) of your web server as the redirect URI and not /oauth2callback.
Assuming that your app is published at www.example.com, just go back to the APIs Console and set it to www.example.com instead of www.example.com/oauth2callback

How to retrieve on which site the web application is currently running?

I am currently running a WCF service on an AppFabric server and my application needs to load a the web.config file dynamically to retrieve custom configuration sections.
On my development machine I can just load the configuration like this:
WebConfigurationManager.OpenMappedWebConfiguration(webMappedFile, virtualPath);
But on the test machine (AppFabric server) I am getting an exception and it seems that I need to specify a third parameter which is actually the site the web application is running on:
WebConfigurationManager.OpenMappedWebConfiguration(webMappedFile, virtualPath, "MySite");
So I tried to hard code it and it worked. Anyway this is not acceptable, so I need to dynamically provide the site to the WebConfigurationManager because I do not on which site the service will be running in the future. Do anybody knows how to achieve that?
Thanks.

If you are running this code as part of handling a request you could use:
Request.ServerVariables("server_name")
see: http://msdn.microsoft.com/en-us/library/ms525396(VS.90).aspx
Edit based on your comment
The parameter that you need is the Site Name, not the machine name, your code be running on many machines. If the code is running somewhere where it no longer knows that it is on a web site, then it is difficult for it to get the name of the web site that it is running on.
You then have two options:
Send the name as a parameter from a layer that has httpconext
Not sure if this will work: but you could try adding a reference to system.web to your project. It may compile, but you could get a null reference exception when you run it. Probably worth a try.

How about Server.MachineName
