Thanks for the feedback. How do I do this? Or is that a forum SysAdmin prerogative?

Yours would make a nice tip/trick, indeed. The process of finding the cause is at least as important as the actual resolution, imho.

I am working on Webhooks Concept. Since Webhooks act like an trigger. It will be firing an event like Update or Insert takes place. Its a MVC application and I have two Controller Home and Webhook Controller. I am passing argument through Query String on Home controller. I have tried Session,TempData, Cookies for passing variable from home to Webhooks HttpContext.Session.SetString("UserName", Request.Query["UserName"].ToString());
and getting session value on webhook controller
HttpContext.Session.GetString("UserName");
Also tried the same for TempData
Issue is On webbooks Controller its coming null.
I need to store parameter (User Name ,password) and reused the same for database related operation
Kindly guide

Session and TempData both rely on cookies to identify the requesting browser. They have a limited life-span, so data you store in them won't hang around forever.
If the data isn't available in the web-hook request, that means either the session has timed out between the initial request and the hook request; or the hook request was made from a different process than the initial request, or using a tool which doesn't store the cookies you set.
You will need to find a different solution. Since you haven't provided any details of what you're actually trying to do, we can't offer any suggestions.
NB: Storing credentials in memory is not a good idea.

I'm now designing a new application that will run only on Windows. No other platforms.
Is there any reason to develop it in .NET Core as opposed to Framework?
The difficult we do right away...
...the impossible takes slightly longer.
|
|
|
|
|
AFAIK, .NET Framework 4.8 is the last of the Windows specific framework. Everything goes .NET (Core) from now on, so it's only a matter of time before your app needs to be converted to a .NET app.
|
|
|
|
|
Technically, the choice is between .NET Framework 4.8 and .NET 5 now.

[HttpPatch("{id:int}")]
public async Task<IActionResult>UpdatePartialAsync(int id, [FromBody] JsonPatchDocument<TEntity> patchEntity)
{
var entity = await _service.ReadAsync(id, false);
if (entity == null)
return NotFound();
try
{
patchEntity.ApplyTo(entity, ModelState);
}
catch(Exception ex)
{
return Ok(ex.Message);
}
entity = await _service.UpdateAsync(id, entity);
return Ok(entity);
}
When accessing this in PostMan, the return is an error, patchEntity has one Operation with all values being null.
Any ideas?

Are we supposed to guess what the error is?

Returning an "OK" response for an exception seems like a particularly bad idea.

You didn't check if patchEntity was null before dereferencing it.

i got error when i want to add sql server in visual studio 2019
Unable to add data connection. Could not find any resources appropriate for the specified culture or the neutral culture. Make sure -Microsoft.VisualStudio.Data.Providers.SqlSetver.SqlViewSupp ort.xmr was correctly embedded or linked into assembly Microsoft.VisualStudio.Data.Providers.SqlServer at compile time, or that all the satellite assemblies required are loadable and fully signed.

This is exactly the same question as the one below. And if both of those accounts belong to you, you should delete one of them.

In Visual studio 2019, when opening the database, the program displays the message:
Could not find any resources appropriate for the specified culture or the neutral culture.
Make sure "Microsoft.VisualStudio.Data.Providers.SqlServer.SqlViewSupport.xml" was correctly embedded or linked into assembly
"Microsoft.VisualStudio.Data.Providers.SqlServer" at compile time,
or that all the satellite assemblies required are loadable and fully signed.
Can anyone advise me how to solve this problem?
Well thank you

Hi all, how can I add the x clear button to textbox controls on a web page ? I've googled and only see references to Telerik - is this doable without third party controls ?

The browser will do it if you use type="search" instead of type ="text". Otherwise, I believe you'll have to write your own css and JS to do it.
There's probably examples online if you want to do it custom.

Hi, I tried type = search but no cross - not a big deal as it's only a personal project

What browser? You do have to start typing for it to show up.

Hi and thanks for replying, I use Firefox, tried the link you posted and still no x
Tried it with Edge and it worked

Yep, you're right. I thought all browsers had started doing that now but I guess not.

Never mind - as I said it's only a personal project - thanks again
