I have working web client, it uses "wwwroot/appsettings.json" file for its configuration.
Now I would like to override just single settings using environment variable for it (as an example, in reality there will be many, arbitrary, overrides). Is there ready to use mechanism, similar to ASP.NET Core server (all it takes is calling extension method and combining json, env. variables)?
I am not asking about multiple .json files and switching between them depending on ENVIRONMENT variable, it is completely different scenario.
So far I didn't find anything even close, so thinking about DIY approach I see an ugly path -- moving client configuration file into hosting server, adding main node in client .json file like "client", using environment variables with prefix "client", merging those data using ASP.NET server mechanism, dumping it back to file for the client usage. And hoping it will work :-).
So I followed DIY path :-) If anyone like it here are the steps:
create 3 files with empty JSON at web client wwwroot -- appsettings.json, appsettings.Development.json and Production version as well
put your entire web client config in appsettings.json at hosting server at "CLIENT" node for example
in your server Startup constructor create configuration as usual, but then fetch entire "CLIENT" section and "jsonize" it back (see: https://stackoverflow.com/a/62533775/6734314) -- convert it to string and write to $"wwwroot/appsettings.{env.EnvironmentName}.json" (where env is IWebHostEnvironment)
And that's it -- I tested it in Development mode and in Production. The only drawbacks I see are:
it looks weird :-)
when executed using VS the written file is put not relative to binary file, but relative to project -- so when you are done you have to delete newly created file (otherwise on the next run VS will complain about conflict between two static files)
You override the settings using env. variables at server side using "CLIENT" prefix, and the rest is as usual.
For the record, I am not saying this is perfect, but I didn't look for anything more than I asked in my question. What I would like to do however is to reduce the number of steps, or even better to use some already existing mechanism. I will be grateful for the improvements/tips within those areas.

I am working on ASP.NET Core 6.0 WebAPI and I need to get data from a CRM system (Sales Logix) using Sage SData API. We have different CRM environments (Production, Staging, Development) and I want to be able to connect (or test) any environment from my WebAPI project.
For that to work, I would like to add a configuration key (to indicate a particular CRM environment) either in appsettings.json (or launchsetting.json). For example when setting is "crmEnvironment": "Development", I want to include a custom json file, named crm-dev.json. Similarly for "crmEnvironment": "Staging", I want to include crm-staging.json.
Each custom json file ideally contains the CRM Url, Username and Password.
Please tell me how can I conditionally add json config files as mentioned above, or is there any better approach of achieving similar results, considering security in mind. Best if I could have custom config files encrypted without having to shift away from the standards, just like we did for Web.Config files by inheriting ProtectedConfigurationProvider.
My questions is similar to How can I add a custom JSON file into IConfiguration?. But since Program.cs no longer uses the Main() method, I am wondering what would be the correct way to add custom json config files.
If this may work, I use this approach.
.AddJsonFile($"Config\\appsettings.{hostContext.HostingEnvironment.EnvironmentName}.json", optional: true, reloadOnChange: true)
And I will have the Json file created for each environment. You can set the environment variable value either via IHost context or may be, simplifying your need by using Environment variable values from your respective environment.
I'm developing a dll that is supposed to be commonly used (in nuget for example). Simple description: my DLL simplifies message exchange with a particular service. It allows to send a request, then retrieve a response. Service is asynchronous and it can create a response in a hour or a day after accepting a request, so after making a request my dll calls service every few minutes to check out for response. The problem is that the app that uses the dll can be restarted therefore storing a request queue in memory isn't a good option (I don't want to lose info about requests). Neither is serializing it to file, because I can't know for sure where my dll will be used - it could be pc app, mvc. My main options is: serialize to file, but give an option to set a address where to place serialized files via web/app.config or make a user to think about it. But maybe there is some better solution about how to store requests queue?
I would put theses type of configuration or data files in a subfolder to the %appdata% folder. You will have write access to files in this folder and the documentation is extensive. Read more here.
in C# you can easily get this folder using:
var appdata = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
Or use Program Data:
var programdata = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
I'm using the AllScripts HelloWorld TouchWorks C# Project, as provided on their site. I've also created a valid application, using the svcUsername and svcPassword on the app.config file to log and added my own appName instead of the default web20.
Didnt change anything else, tried with many different application ID's, all trying to log into the default sandbox server in the example and some trying other sandboxes.
Regardless of what I do, I keep getting
Error: Service Application not licensed on this server!
Despite this being a sandbox server, thus suppouseably accessable to all applications.
What did I do wrong?
edit: Tried to do the same in Slueth, I get the same error.
It's more simple than it seems. Sandbox servers DO require licenses. Talked with the staff, they're nice people, so they manually added me after a few explanations of my requirements.
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.
I have an application written in .NET 3.5 with C# as the language. I'm using Web Forms, but using url routing with the routes defined in my global file. Everything is working as expected. In order for the pretty paths (see: user/665 instead of user.aspx?uid=665) to work properly, I had to add a wildcard mapping in IIS5.1 (local box, not test, staging, or production) the aspnet_isapi file for the 2.0 framework. Everything works fine.
Now, my site needs a plugin for PHP. However, the PHP files are now being serviced by ASP.NET due to the wild card mapping, and hence are not processed by the PHP interpretter. Is there any way to get around this? Would I have to add some sort of handler to my web app that will take all PHP requests being handled by the ASP.NET framework and have them routed to the PHP engine? Is there an easier way? Maybe a way to exclude them in the web.config (PHP files) and have them served by the proper PHP engine?
Thanks all!

This is a solution, but is not an elegant way (IMHO):
Create a virtual directory
Have it point to the folder with the files (in this case, a PHP plugin)
Give it the proper permissions
Change the config options for the virtual directory in IIS and make sure the wildcard mapping for that directory is removed.
This works like a charm for my situation. However, is there any way to not have to deal with virtual directories?
The problem is that the PHP extension needs to be registered.
In IIS Manager right-click on Default Website -> Properties -> Home Directory -> Configuration
Under Application Mappings make sure that .php is added and is it pointing to PHP.EXE. There should be an entry like this: extension .php, executable path C:\PHP\PHP.EXE %s %s
From what I gather, the problem is that ASP.NET is attempting to route your PHP requests, so what I would do is add a StopRoutingHandler() to your routes in the global.asax. Something like this should work:
routes.Add(new Route("{resource}.php/{*pathInfo}", new StopRoutingHandler()));
Edit: Be mindful that routes are processed in order, so I would add this to the top of your routes.
