$.getJSON() Not Loading JSON File Within Visual Studio Project In ASP.NET Web Forms

-
Hi,
I was trying to load a JSON file located within my Visual Studio project using $.getJSON(), however the code below doesn't work as expected. 
$.getJSON('/Assets/misc/employee.json', function (data) {
 alert('processing!');
})
.done(function (r) {
 alert(r.message);
})
.fail(function (s) {
 alert('oops the file is missing!');
});
After investigating for a few hours, I tested the local path of the JSON file such as http://localhost:3766/Assets/misc/employee.json and the result was an exception "HTTP Error 404.3 - Not Found The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.".
I remember the solution in one of my ASP.NET project was to set the MimeMap in the web.config inside the system.webServer element. After setting the MimeMap for json files, I can now load local JSON files using $.getJSON(). 
<system.webServer>
 <staticContent>
   <mimeMap fileExtension=".json" mimeType="application/json" />
 </staticContent>
</system.webServer>

How To Insert Or Add Emojis In Microsoft Teams Status Message

Good day Gents! I was trying to update my Microsoft Teams status and was wondering if I can add or insert emoji. For editing or adding new teams status, only text fields are available and there's no emoji icon similar to writing a teams message. After googling for a few minutes, I found this link Emoji's in status which is a feature request in Microsoft Teams User's Voice Forum. So far this upgrade request only has thirty votes which is relatively small and may be considered a low priority for the product team to implement. Given the limitations at hand, I tried several approach including copying an emoji in a chat message which didn't work and later found a solution using Microsoft Outlook 365. First is to create a new email message in Microsoft Outlook and press (Window Key + .). The emoji dropdown control will appear. Next is to select the emoji that you wanted to add to Teams. Copy the emoji from the newly created email message template and paste that to Micr

Pass GUID As Parameter To Action Using ASP.NET MVC ContribGrid

-
Hi, In a scenario where in you want to pass a GUID object to an Action Parameter, the parameter might contain a null value. Since Guid is not nullable, you can't simply just pass it to an action parameter because Action parameters require nullable and reference types. You might encounter an error like this: An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter Assuming you have an aspx view below: <div> <% Html.Grid(Model).Columns (c => { c.For(m => m.Price); c.For(m => m.ProductName); c.For(m => m.ProductID); c.For( "View Person" ).Named( "" ).Action(m => { %> <td> <%= Html.ActionLink( "View Person" , "ProductDetail" , "Home" , new { @id = m.ProductID.ToString() }) %> </td> <% }); %> <% }).Render(); %> </div> and an action
