Create A NuGet Package Using Visual Studio 2017

-
Hello all!

You may have noticed that the trend in adding components or dll's to a project is through a technology called NuGet Package and with that I'll demonstrate on how to create a simple C# Library NuGet package using Visual Studio 2017.
Below are the steps to follow.
1. First is to create a C# class library project called StringLib and add a class with a single method to convert the first letter of a string to uppercase. 
public class ToUpperCase
    {
        /// <summary>
        /// Change first letter to uppercase
        /// </summary>
        public string ToUpperFirstLetter(string s)
        {
            if (string.IsNullOrEmpty(s))
            {
                return string.Empty;
            }

            char[] a = s.ToCharArray();
            a[0] = char.ToUpper(a[0]);
            return new string(a);
        }
    }

2. Build the project to generate a .dll file.
3. Copy the .dll or any files to be included in the package to a shared drive.
4. Download nuget.exe file from this website: Nuget.org
5. Copy the nuget.exe file to the root of your project.
6. Open command prompt as an administrator, change the directory to the root of your project and execute statement "nuget spec" to create a Package.nuspec file.

7. Edit the information of the nuspec file based on the project's id, description, authors/owners, version, purpose and location of the files. Make sure that the location of the assembly and file(s) included are correct.

8. Navigate again to the command prompt and execute statement "nuget pack Package.nuspec". This will create a a nuget package file at the root of the project such as "StringLib.1.0.0.nupkg". Create A NuGet Package Using Visual Studio 2017
9. Copy the newly created nuget package to the shared drive.
Now that we have successfully created the package, we need to add it in Visual Studio's NuGet Package Manager and use it to one of our projects.
1. Open Visual Studio, and go to Tools->Options->NuGet Package Manager-> Package Sources
2. Add the newly created package by adding an appropriate Name and it's location(shared drive). Click Ok.

To use the package in a .NET Project:
 1. Right click on the project and select "Manage NuGet packages".
2. Click Browse and then select the package from the "Package source:" dropdown.
3. Click Install.

That's it. You should be able to use the string method you created earlier. :-)

The complete script is found in this post WPF CRUD With DataGrid, Entity Framework And C#.NET 2. Create a WPF Project and add four folders called DataAccess, Model, View and ViewModel. 3. Your project structure may look similar with the screenshot provided below. II. Coding The Model and Repository Class 1. Inside the Model folder, add an ADO.NET Entity Data Model that connects to the Students table in your database. On my part, I named it StudentModel . 2. For the connectionstring name in App.config file, I

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
