Blazor App No Longer Compiles
I just updated MS Visual Studio 2022 Community Edition to version 18.11.0. After the update, Blazor apps no longer compile in for the release version, they still work for the debug version of the project. This is true with existing projects and new Blazor App projects created with C#. I get this error message: ===================== 10/16/2026 4:16:12 AM Project: BillByrnes.csproj Recoverable System.AggregateException: One or more errors occurred. ---> (Inner Exception #0) Microsoft.Assumes+InternalErrorException: No pending webSession for web server 1 at Microsoft.Assumes.Fail(String message) at Microsoft.WebTools.ProjectSystem.HotReload.WebHotReloadAgent.StartSession(IWebServer webServer) at Microsoft.WebTools.ProjectSystem.Debugger.BaseDebugTargetsProvider.<OnAfterLaunchAsync>d__84.MoveNext() <--- (Inner Exception #0) =================== Any help would be appreciated.

Simple request for Visual Studio's Find and Replace operation
Doing a Find + Replace operation in VS, I could wish there was an option, when selecting to do so over the whole project or solution, to choose which types of files to include or exclude. For example, in a classic Web Forms project, I'd like to omit the designer pages. I've been caught out by this ore than once ... :( (More fool I...)Mastering Query Fields in Azure AI Document Intelligence with C#
Introduction Azure AI Document Intelligence simplifies document data extraction, with features like query fields enabling targeted data retrieval. However, using these features with the C# SDK can be tricky. This guide highlights a real-world issue, provides a corrected implementation, and shares best practices for efficient usage. Use case scenario During the cause of Azure AI Document Intelligence software engineering code tasks or review, many developers encountered an error while trying to extract fields like "FullName," "CompanyName," and "JobTitle" using `AnalyzeDocumentAsync`: The error might be similar to Inner Error: The parameter urlSource or base64Source is required. This is a challenge referred to as parameter errors and SDK changes. Most problematic code are looks like below in C#: BinaryData data = BinaryData.FromBytes(Content); var queryFields = new List<string> { "FullName", "CompanyName", "JobTitle" }; var operation = await client.AnalyzeDocumentAsync( WaitUntil.Completed, modelId, data, "1-2", queryFields: queryFields, features: new List<DocumentAnalysisFeature> { DocumentAnalysisFeature.QueryFields } ); One of the reasons this failed was that the developer was using `Azure.AI.DocumentIntelligence v1.0.0`, where `base64Source` and `urlSource` must be handled internally. Because the older examples using `AnalyzeDocumentContent` no longer apply and leading to errors. Practical Solution Using AnalyzeDocumentOptions. Alternative Method using manual JSON Payload. Using AnalyzeDocumentOptions The correct method involves using AnalyzeDocumentOptions, which streamlines the request construction using the below steps: Prepare the document content: BinaryData data = BinaryData.FromBytes(Content); Create AnalyzeDocumentOptions: var analyzeOptions = new AnalyzeDocumentOptions(modelId, data) { Pages = "1-2", Features = { DocumentAnalysisFeature.QueryFields }, QueryFields = { "FullName", "CompanyName", "JobTitle" } }; - `modelId`: Your trained model’s ID. - `Pages`: Specify pages to analyze (e.g., "1-2"). - `Features`: Enable `QueryFields`. - `QueryFields`: Define which fields to extract. Run the analysis: Operation<AnalyzeResult> operation = await client.AnalyzeDocumentAsync( WaitUntil.Completed, analyzeOptions ); AnalyzeResult result = operation.Value; The reason this works: The SDK manages `base64Source` automatically. This approach matches the latest SDK standards. It results in cleaner, more maintainable code. Alternative method using manual JSON payload For advanced use cases where more control over the request is needed, you can manually create the JSON payload. For an example: var queriesPayload = new { queryFields = new[] { new { key = "FullName" }, new { key = "CompanyName" }, new { key = "JobTitle" } } }; string jsonPayload = JsonSerializer.Serialize(queriesPayload); BinaryData requestData = BinaryData.FromString(jsonPayload); var operation = await client.AnalyzeDocumentAsync( WaitUntil.Completed, modelId, requestData, "1-2", features: new List<DocumentAnalysisFeature> { DocumentAnalysisFeature.QueryFields } ); When to use the above: Custom request formats Non-standard data source integration Key points to remember Breaking changes exist between preview versions and v1.0.0 by checking the SDK version. Prefer `AnalyzeDocumentOptions` for simpler, error-free integration by using built-In classes. Ensure your content is wrapped in `BinaryData` or use a direct URL for correct document input: Conclusion Using AnalyzeDocumentOptions provides a cleaner and more reliable way to work with query fields in Azure AI Document Intelligence using C#. By aligning with the latest SDK approach, developers can simplify implementation, reduce common errors, and improve code maintainability. Keeping up with SDK enhancements and recommended practices ensures more accurate and efficient document data extraction. As Azure AI capabilities continue to evolve, adopting modern integration patterns will help you build scalable and future-ready document processing solutions with greater confidence.

If you're curious about building AI solutions but don’t know where to start, Microsoft’s AI Toolkit is a great place to begin. Whether you’re a student, developer, or just someone exploring AI for the first time, this toolkit helps you build real-world solutions using Microsoft’s powerful AI services. In this blog, I’ll Walk you through what the AI Toolkit is, how you can get started, and where you can find helpful demos and ready-to-use code samples. What is the AI Toolkit? The AI Toolkit is a collection of tools, templates, and sample apps that make it easier to build AI-powered applications and copilots using Microsoft Azure. With the AI Toolkit, you can: Build intelligent apps without needing deep AI expertise. Use templates and guides that show you how everything works. Quickly prototype and deploy apps with natural language, speech, search, and more. Watch the AI Toolkit in Action Microsoft has created a video playlist that covers the AI Toolkit and shows you how to build apps step-by-step. You can watch the full playlist here: It is especially useful for developers who want to bring AI into their projects, but also for beginners who want to learn by doing. AI Toolkit Playlist – https://aka.ms/AIToolkit/videos These videos help you understand the flow of building AI agents, using Azure OpenAI, and other cognitive services in a hands-on way. Explore Sample Projects on GitHub Microsoft also provides a public GitHub repository where you can find real code examples built using the AI Toolkit. Here’s the GitHub repo: AI Toolkit Samples – https://github.com/Azure-Samples/AI_Toolkit_Samples This repository includes: Sample apps using Azure AI services like OpenAI, Cognitive Search, and Speech. Instructions to deploy apps using Azure. Code that you can clone, test, and build on top of. You don’t have to start from scratch just open the code, understand the structure, and make small edits to experiment. How to Get Started Here’s a simple path if you’re just starting: Watch 2 or 3 videos from the AI Toolkit Playlist. Go to the GitHub repository and try running one of the examples. Make small changes to the code (like updating the prompt or output). Try deploying the solution on Azure by following the guide in the repo. Keep building and learning. Why This Toolkit is Worth Exploring As someone who is also learning and experimenting, I found this toolkit to be: Easy to understand, even for beginners. Focused on real-world applications, not just theory. Helpful for building responsible AI solutions with good documentation. It gives a complete picture — from writing code to deploying apps. Final Thoughts The AI Toolkit helps you start your journey in AI without feeling overwhelmed. It provides real code, real use cases, and practical demos.
