[Suggestion 1][Allow Language Selection During .NET Installation]
Hi, 1. Context: Currently, when installing the .NET SDK or runtime, multiple language resource folders are automatically included in the installation directory. 2. Problem: Many developers only require a single language, typically English and the additional localization files take up unnecessary disk space and clutter the installation directory. Currently, the installer does not provide an option to select which languages should be installed. Removing these manually is time-consuming and could potentially break application dependencies if done incorrectly. 3. Proposed Solution: Introduce an option in the .NET installer that allows users to select or deselect language packs during installation. This feature could be similar to the "Individual components" selection available in the Visual Studio Installer, where users can choose exactly what they need, ensuring a more streamlined installation. This would help: Reduce disk space usage. Improve installation customization. Provide a cleaner development environment. 4. What do you think about this suggestion ? Thank you for considering this request and I’m happy to provide additional details or insights if needed.
Do I need to upgrade Microsoft.AspNetCore.* NuGet packages after upgrading the .NET Runtime?
Hi, I'm encountering an issue with our SCA (Software Composition Analysis) scan, which reports several known vulnerabilities in .NET Core components. Specifically, the scan detects that the following packages are still on version 8.0.0, which are flagged as vulnerable: Microsoft.AspNetCore.Authorization Microsoft.AspNetCore.Components Microsoft.AspNetCore.Http.Connections.Client Microsoft.AspNetCore.SignalR.Client The scanner recommends upgrading these packages to version 8.0.15 to resolve the issues. To address this, I upgraded the .NET Runtime on our environment to version 8.0.15. However, the SCA scan still reports the same vulnerabilities, indicating that the vulnerable component versions have not changed. My question is: Do I also need to manually upgrade the corresponding NuGet package versions in the project to 8.0.15, or is upgrading the .NET Runtime alone sufficient to ensure these components are updated as well? Any clarification would be appreciated. Thank you!Host Remote MCP Servers on App Service: Updated samples now with new languages and auth support
If you haven't seen my previous blog post introducing MCP on Azure App Service, check that out here for a quick overview and getting started. In this blog post, I’m excited to share some updates for our App Service MCP samples: new language samples, updated functionality to replace deprecated methods, and built-in authentication and authorization—all designed to make it easier for developers to host MCP servers on Azure App Service. 🔄 Migrating from SSE to Streamable HTTP The original .NET sample I shared used Server-Sent Events (SSE) for streaming responses. However, SSE has since been deprecated in favor of streamable HTTP, which offers better compatibility and performance across platforms. To align with the latest MCP specification, I’ve updated the .NET sample to use streamable HTTP: ✅ Updated .NET Sample: remote-mcp-webapp-dotnet This update ensures your MCP server is compliant with the latest protocol guidance. All additional samples in this post also use streamable HTTP. 🌐 New Language Samples: Python and Node.js To support a broader range of developers, I’ve created new MCP server samples in Python and Node.js. These samples are lightweight, easy to deploy, and follow the same architectural principles as the .NET version. 🐍 Python Sample: remote-mcp-webapp-python 🟢 Node.js Sample: remote-mcp-webapp-node Each sample is designed to run seamlessly on Azure App Service, with minimal configuration required. 🔐 Secure Your MCP Server with Auth Support Security is a critical aspect of any remote server. To help developers implement secure MCP servers, I’ve added new samples that demonstrate how to use authentication and authorization mechanisms aligned with the MCP authorization specification. 🔐 Python + Basic Auth: remote-mcp-webapp-python-auth 🔐 Python + OAuth: remote-mcp-webapp-python-auth-oauth These samples show how to validate incoming requests using industry-standard methods, making it easier to integrate with identity providers and enforce access control. Use Basic Auth for a quick and easy way to add authentication to your MCP server. Or use OAuth and configure it with Microsoft Entra ID for an even more secure server. 🚀 Get Started Today Each sample includes detailed instructions for deployment, configuration, and testing. Whether you're building in .NET, Python, or Node.js, you can now host a secure, standards-compliant MCP server on Azure App Service with ease. Follow the guidance in the respective README.md files to get started today. All samples include Azure Developer CLI (azd) templates to get you up and running within minutes. 💬 Join the Conversation I’d love to hear how you’re using these samples or what features you’d like to see next. Feel free to open issues or contribute to the repositories on GitHub. Or leave comments on this post if you have any questions, feedback, or requests.Stefan Pölz - Null & Void, everything about nothing in .NET

The following PowerShell code: class MyClass { } class MyClass1 : MyClass { [void] OutMsg([string] $Str) { Write-Host -Object "MyClass1: $Str" } } class MyClass2 : MyClass { [void] OutMsg([string] $Str) { Write-Host -Object "MyClass2: $Str" } } [MyClass[]] $ClassArray = @([MyClass1]::new(), [MyClass2]::new()) $ClassArray.OutMsg('TestString') outputs: MyClass1: TestString MyClass2: TestString A Get-Member -InputObject $ClassArray shows me that the array object itself has no OutMsg method. Why can I successfully call $ClassArray.OutMsg('TestString') though (looks like this calls the OutMsg method of each array member in turn)?
