StringLibrary -> C:\Projects\ClassLibraryProjects\StringLibrary\bin\Debug\net7.0\StringLibrary.dllĪdd a console application that uses the class library. The terminal output looks like the following example: Microsoft (R) Build Engine version 16.7.4+b89cb5fde for. Run the following command to build the solution and verify that the project compiles without error. StartsWithUpper is implemented as an extension method so that you can call it as if it were a member of the String class. The Char.IsUpper(Char) method returns true if a character is uppercase. The Unicode standard distinguishes uppercase characters from lowercase characters. This method returns a Boolean value that indicates whether the current string instance begins with an uppercase character. The class library, UtilityLibraries.StringLibrary, contains a method named StartsWithUpper. Public static bool StartsWithUpper(this string? str) Open Class1.cs and replace the code with the following code. ![]() The TargetFramework element shows that the project targets. In Explorer, open StringLibrary/StringLibrary.csproj. The terminal output looks like the following example: Project `StringLibrary\StringLibrary.csproj` added to the solution.Ĭheck to make sure that the library targets. Run the following command to add the library project to the solution: dotnet sln add StringLibrary/StringLibrary.csproj Restored C:\Projects\ClassLibraryProjects\StringLibrary\StringLibrary.csproj (in 328 ms). Running 'dotnet restore' on StringLibrary\StringLibrary.csproj. The terminal output looks like the following example: The template "Class library" was created successfully. The -o or -output command specifies the location to place the generated output. In the terminal, run the following command to create the library project: dotnet new classlib -o StringLibrary NET class library project named "StringLibrary" to the solution.

In the Terminal, enter the following command: dotnet new sln The Terminal opens with the command prompt in the ClassLibraryProjects folder. Open the Terminal in Visual Studio Code by selecting View > Terminal from the main menu. In the Open Folder dialog, create a ClassLibraryProjects folder and click Select Folder ( Open on macOS). You'll add additional, related projects to the same solution. A solution serves as a container for one or more projects. Start by creating a blank solution to put the class library project in.
