var projectContent = new CSharpProjectContent(); var fileText = "public class MyClass {}"; var file = new CSharpFile("MyClass.cs", fileText); projectContent = projectContent.AddOrUpdateFiles(file);
var projectContent = new CSharpProjectContent(); var fileText = "public class MyClass {}"; var file = new CSharpFile("MyClass.cs", fileText); projectContent = projectContent.AddOrUpdateFiles(file); var updatedFileText = "public class MyClass { public int MyProperty { get; set; } }"; var updatedFile = new CSharpFile("MyClass.cs", updatedFileText); projectContent = projectContent.AddOrUpdateFiles(updatedFile);In this example, a CSharpProjectContent object is created and a new file "MyClass.cs" is added to it. The file is then updated with a new property "MyProperty" using the same file name but with updated contents. The changes are made to the project content using the AddOrUpdateFiles method. The package/library for IProjectContent and CSharpProjectContent is "Microsoft.CodeAnalysis.CSharp.Workspaces".
