Async programming

 Async Programming

Obviously only do these in methods that are marked async.

1) Instead of .ToList() think about .ToListAsync(cancelToken).Result;  This does not apply to IEnumerable that does not have an ToListAsync().  IQueryable does have it. 

2) Instead of .FirstOrDefault(), think about .FirstOrDefaultAsync(cancelToken).Result;


Love this article:

This is ok:

Upgrading to .NET8 from desktop versions 4.8.X

Upgrade to Latest .NET OVERALL     Problems and differences encountered taking applications from .NET 4.8 desktop to .NET 8 . SUGGESTION    Rebuild the solution and project files from scratch with latest .NET 8. PROBLEMS APIs    On later .NET APIs (post 4.8 desktop), you need to be extra carefully about how the inbound objects are declared.  So if integer in Postman, then must be integer in object.  In older .NET, they accept properties as strings.       Example - Say body in Postman is:          {     "SettingData" : 31000 }    Pretend endpoint method is: [HttpPut("cache/resettimer")] [Produces("application/json")] [ProducesResponseType(typeof(ResetCacheResponse), Status200OK)] public async Task<HttpResponseMessage> MyMethod ([FromBody] InputData input)    Later .NET must be: public class InputData { public int SettingData { get; set; } } ...

JSON Web Tokens

 JSON Web Tokens (JWT)   A JSON Web Token (JWT) is commonly used for authentication and authorization in web applications and APIs. Essentially, JWTs encode info about a user or entity into a JSON object, which is then digitally signed and/or encrypted.  A JWT consists of three parts, separated by dots (.):  1. Header: Contains metadata about the token, such as the signing algorithm (e.g., HMAC SHA256, RSA SHA256) and the token type (JWT).  2. Payload: Contains the claims, which are statements about an entity (e.g., user ID, role, expiration time).   3. Signature: Verify that the JWT sender is who they claim to be and that the message hasn't been tampered with.  How it works:   Authentication: A user logs in, and the server creates a JWT containing user info and other relevant claims.    Token Transmission: The server sends the JWT to the client (e.g., browser).    Subsequent Requests: The client includes the JWT in the au...

GHL > Set website so shorter URL address

GHL > Set website so shorter URL address Background:  In GoHighLevel, you can  set a specific page as the default page   for your website or funnel, essentially making it the "index.html" equivalent for your domain. This page will be the first one displayed when someone visits your domain without specifying a specific page path.   Example:      1) GHL > Site > pick your funnel or website > Edit it.       2) Notice where it puts the website:     3) If my  https://aiappointmentbooker.com/  is not working but works when I go to  https://aiappointmentbooker.com/home-page-3213  like above, then you need to fix your index.html by doing these steps. Here's how you can do it: Go to Domains:  In your GoHighLevel account, go to  Settings > Domains . Find and Edit Your Domain:  Find the domain you want to configure and click on the edit icon next to it. Set the Default Page:  Set...
