Edm Model Generation Fails
Using an Azure ASP.NET MVC API from a Maui app, I am encountering the following error in the app when attempting to access the API. A few days ago, the initalization was working properly. The cloud app has been under further development, but the base api code has not been modified, only the response from the endpoints. The latest release NuGets are in use. What elements are being sought? System.TypeInitializationException: The type initializer for 'GeneratedEdmModel' threw an exception. ---> System.InvalidOperationException: Sequence contains no elements at System.Linq.ThrowHelper.ThrowNoElementsException() at System.Linq.Enumerable.First[TSource](IEnumerable`1 source) at SentryCloud.Models.Container.GeneratedEdmModel.CreateXmlReader()
Windows Forms user control layout issues at runtime
I'm hoping the good folls of this community can help me figure out what's going on with a Windows Forms user control that I created and am trying to use. I created a user control that represents a single band of a parametric equalizer. In the designer, the control looks like this: When I debug the control in the Test Container, things look good: If we take a look at the actual PEQ application that will use the control, things still look OK in the designer: It's only when I fire up the application that things go... awry: What happened to all the TextBoxes? And the ComboBoxes? I''ve got a feeling that the fix for this is something really simple, and I'm going to feel like a complete idiot for not figuring out the obvious. Can anyone tell me what my dumb self did wrong?
It appears and error that does not exist
I am using VS 2022 Community and when i develope asp.net apps it happens sometimes that it appears an error that does not exist adn only after many hours of searching for the error or rewriting the same code the app begins to run correctly. Somehitng simmilar happened to any of you ? how can i avoid these strange behaviour of the compiler ? Thank you in advance Luis MartinConnect .Net (4.6.2) to Dataverse using the Dataverse plugin
Hi Microsoft Tech Community, We have a Dataverse environment in our tenant, and I have its URL. I'm building a .NET application and need to connect it to Dataverse for data access. From the Learn docs, ChatGPT, and Copilot, it seems I need to use an App ID (Client ID) and Client Secret in the connection string (e.g., via Microsoft.PowerPlatform.Dataverse.Client). However, the Dataverse environment itself doesn't expose any App ID or Client Secret—where would I even find those if they exist? Here's the code snippet we found online that's using OAuth with AppId and RedirectUri, but we're unsure about the app registration part: using Microsoft.Crm.Sdk.Messages; using Microsoft.PowerPlatform.Dataverse.Client; using Microsoft.Xrm.Sdk; class Program { // TODO Enter your Dataverse environment's URL and logon info. static string url = "https://yourorg.crm.dynamics.com"; static string userName = "email address removed for privacy reasons"; static string password = "yourPassword"; // This service connection string uses the info provided above. // The AppId and RedirectUri are provided for sample code testing. static string connectionString = $@" AuthType = OAuth; Url = {url}; UserName = {userName}; Password = {password}; AppId = 51f81489-12ee-4a9e-aaae-a2591f45987d; RedirectUri = app://58145B91-0C36-4500-8554-080854F2AC97; LoginPrompt=Auto; RequireNewInstance = True"; static void Main() { //ServiceClient implements IOrganizationService interface IOrganizationService service = new ServiceClient(connectionString); var response = (WhoAmIResponse)service.Execute(new WhoAmIRequest()); Console.WriteLine($"User ID is {response.UserId}."); // Pause the console so it does not close. Console.WriteLine("Press the <Enter> key to exit."); Console.ReadLine(); } } Do I need to create a separate app registration in Microsoft Entra ID (Azure AD), link it to the Dataverse environment (perhaps as an application user?), and then use that app's Client ID/Secret in my .NET code? If so, could someone outline the exact steps, including permissions and Power Platform admin center setup? Any guidance or links to official walkthroughs would be greatly appreciated—thanks!The Evolution of Conversational AI in Microsoft’s Ecosystem
Over the past two decades, conversational AI has shifted from a futuristic curiosity to a core part of how we interact with technology. And while many companies have shaped this field, one of the most influential players has consistently been Microsoft. From the early days of clippy (yes, that Clippy) to the cutting-edge Copilot ecosystem today, Microsoft’s journey mirrors the broader evolution of conversational AI itself. It’s a story of ambition, experimentation, setbacks, breakthroughs, and ultimately, transformation. In this blog, we’ll explore how conversational AI has developed within Microsoft’s ecosystem—how it started, the key milestones along the way, and where it’s all heading next. https://dellenny.com/the-evolution-of-conversational-ai-in-microsofts-ecosystem/GitHub Copilot for Python: Real-World Coding Scenarios & Practical Examples
When GitHub Copilot first launched, many developers wondered whether an AI pair-programmer could truly make an impact on everyday coding tasks. Today, after widespread adoption, the verdict is clear: Copilot can significantly boost productivity, reduce repetitive work, and help developers focus on high-level thinking. This is especially true for Python developers, who frequently deal with tasks ranging from data processing to API integration, automation, and web development. In this blog, we’ll explore real-world Python scenarios where GitHub Copilot shines. Whether you’re a beginner experimenting with your first scripts or a seasoned engineer working on large systems, Copilot can help streamline your workflow in ways that feel surprisingly human. https://dellenny.com/github-copilot-for-python-real-world-coding-scenarios-practical-examples/Security and Compliance Considerations When Using Copilot in Enterprise Environments
We see these new AI tools, like Copilot, helping us do work faster, write better emails, and summarize long documents. It’s like having a super-smart assistant right next to you. But for people who look after company rules, like the security and compliance teams, a new tool also means new questions. We need to be sure that while Copilot helps us be fast, it does not accidentally share our company’s secrets or break any important laws about data. This is what we call security and compliance—it’s about keeping our digital house safe and following the rules. In this blog, I want to talk about the important things we must think about when we bring a powerful tool like Copilot into our enterprise environment. It’s not just about turning it on; it’s about making sure we set it up in a smart and safe way. https://dellenny.com/security-and-compliance-considerations-when-using-copilot-in-enterprise-environments/Turbocharge Your Coding Top GitHub Copilot Shortcuts and Productivity Tips for VS Code
GitHub Copilot isn’t just a fancy autocomplete; it’s a true AI pair programmer that can fundamentally change how you write code. But like any powerful tool, mastering it requires knowing the hidden tricks and, most importantly, the keyboard shortcuts that keep your hands on the keys and your focus in the flow. If you’re using VS Code, you’ve got the ideal setup. Let’s dive deep into the must-know shortcuts and best practices to transform you from a Copilot novice into a speedy! https://dellenny.com/turbocharge-your-coding-top-github-copilot-shortcuts-and-productivity-tips-for-vs-code/Your Guide to Debugging and Reviewing Copilot-Generated Code
The rise of AI coding assistants like GitHub Copilot has been a game-changer. It’s like having a hyper-efficient, incredibly well-read junior developer peering over your shoulder, offering code snippets and completing functions almost as fast as you can think. This boost in productivity is phenomenal—until a tricky bug crawls into a piece of AI-generated code, or a security vulnerability lurks undetected. The truth is, while Copilot is an amazing accelerator, it is not a replacement for a developer’s critical thinking and review process. AI-generated code, for all its brilliance, is still code written by an engine trained on massive datasets, including the good, the bad, and the slightly outdated. You, the human developer, are the crucial “Human-in-the-Loop”—the final guardian of code quality, security, and logic. This blog post is your essential guide to navigating this new landscape. We’ll lay out the best practices for debugging and reviewing code generated by your AI partner, ensuring you leverage its speed without compromising on quality or security. https://dellenny.com/your-guide-to-debugging-and-reviewing-copilot-generated-code/

PowerShell hosting in C#
Don't know if this is the correct place to post my question... I want to use the PowerShell 7 cmdlet Get-ClusterResource in C# under Windows 11, like this: using System.Collections.ObjectModel; using System.Management.Automation; namespace PSHosting; class Program { static void Main() { using (var powerShell = PowerShell.Create()) { powerShell.AddScript("Get-ClusterResource -Cluster 'WSFC1'"); Collection<PSObject> result = powerShell.Invoke(); } } I have the RSAT FailoverCluster Windows package installed. When calling Get-ClusterResource in a PowerShell session, PowerShell uses the implicit remoting technique to create and load a proxy module for the original FailoverCluster module, and then execute the command on the remote computer. At some point during my attemps to get a working Get-ClusterResource in my C# code, I included the following in the above code (before the using statement): A Set-ExecutionPolicy command that lets PowerShell execute arbitrary scripts (most probably required because module loading (see below) and/or implicit remoting would run .ps1 and/or .psm scripts contained in the FailoverCluster module folder) An Import-Module command that loads the FailoverCluster module into the current session Interestingly, the above code still works in my environment after stripping the commands 1. and 2. above from the code, deleting the proxy module C:\Users\<UserName>\AppData\Local\Temp\remoteIpMoProxy_FailoverClusters_2.0.0.0_localhost_<ID>, and rebooting the computer. My ultimate goal is to publish code like the above together with all required modules and other stuff so it can run successfully on a computer with stock Windows 11 installed only (single exception: .NET runtime matching my C# version is installed, so I don't need to distribute that too). From what I think I know at the moment, this means that I need to: Include the FailoverCluster module folder in my publication, and Add the commands 1. and 2. above in my code (hopefully, referencing the FailoverCluster module works with a relative path) Am I correct here, or do I miss something out?
