.NET runtime issues - application not starting up
Hello, We have a .NET based application built using the .NET framework 8.0. The application runtimeconfig.json file shows this: MyApp.runtimeconfig.json "tfm": "net8.0", "frameworks": [ { "name": "Microsoft.NETCore.App", "version": "8.0.0" }, { "name": "Microsoft.WindowsDesktop.App", "version": "8.0.0" } ], Please note that we have Published the application and verified that only .NET version 8.0.16 components, DLLs etc are required. Anything higher than this does not show up. From the cmd prompt, the following runtimes are shown to be installed on the system: >dotnet --list-runtimes Microsoft.AspNetCore.App 8.0.21 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App] Microsoft.NETCore.App 8.0.20 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] Microsoft.WindowsDesktop.App 8.0.20 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App] However, when we try to start a Windows service which is installed as part of the application, it does not start up, and the Windows Event Viewer shows the following error: "Description: A .NET application failed. Application: MyAppControllerService.exe Path: C:\MyApp\MyAppControllerService.exe Message: You must install or update .NET to run this application. App: C:\MyApp\MyAppControllerService.exe Architecture: x64 Framework: 'Microsoft.NETCore.App', version '8.0.21' (x64) .NET location: C:\Program Files\dotnet\ The following frameworks were found: 8.0.20 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] Learn more: https://aka.ms/dotnet/app-launch-failed To install missing framework, download: https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=8.0.21&arch=x64&rid=win-x64&os=win10" So, the issue is, even with Microsoft.WindowsDesktop.App 8.0.20 being installed on the system, it still asks for the .NET 8.0 Runtime (v8.0.21) to be installed. Please let me know why this is so? Since, as per this: https://learn.microsoft.com/en-us/dotnet/core/install/windows .NET Desktop Runtime includes the .NET runtime as well, and Microsoft.WindowsDesktop.App 8.0.20 is installed. Thanks in advance, JY
How to respond to upgrade-assistant cli prompts?
Bear with me please, I have not touched this stuff in a few years. Trying to upgrade Xamarin project to .Net Maui using CLI (latest version of VS 2022 cannot find the Upgrade assistant extension). I have downloaded the upgrade-assistant, but am not familiar with how to reply\how to make a selection of what is displayed after I enter "upgrade-assistant upgrade project-name" (it does not execute and instead displays information...see attached image). Is what is being display telling me that I need to ctrl-c out of this and re-enter the command using what they are showing? Please give me an example of using the Side-by-side upgrade. Is is also telling me that I need to do something with NuGet also on the command line? Thanks.

Trying to add new Type to Dotnet Runtime from github
Hi I'm trying to modify the .NET runtime from github.com/dotnet/runtime. I created a copy of the Dictionary class called Dictionary2 in these source code files: C:\rt5\src\libraries\System.Collections\ref\System.Collections.cs C:\rt5\src\libraries\System.Private.CoreLib\src\System\Collections\Generic\Dictionary.cs When I use dot peek from Jetbrains, Dictionary2 exists in my System.Collections.dll, but when I import System.Collections.dll in my main console C# application, Dictionary2 gives me compiler errors. Am, I missing some code somewhere? Can you guys help me out here? Thanks!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!
Can't able to Upload Images on Azure Server if it is more than 128KB
Hi Everyone , I am trying to upload image and store but when i do it in my local server its working fine but when i push the same code in server i am getting entity too large I reached out microsoft support they are telling that "The content type format is supposed to be image as example given to upload the image file otherwise the application gateway will not understand the image and tries to accept only 128KB which is why the request is not accepted with Application Gateway. " when i am debugging i am getting same content type = image/jpeg .

I frequently deal with insurance documentation and recently had to work with the ACORD 23 Vehicle Insurance Certificate. I’ve been using Windows 11 and was looking for the most efficient way to fill, edit, and save these forms digitally without printing them out. While browsing, I found AcordForm – it lets you view and understand various ACORD forms like the 23, 25, and more. It’s been helpful for referencing and understanding the format. However, I’d love some advice from the community: What’s the best Microsoft-supported tool for filling out ACORD PDF forms? Is Microsoft Edge’s PDF editor reliable enough, or should I be using Microsoft Word with PDF add-ins? Any integration tips with OneDrive or SharePoint for document storage?. Thanks in advanceUsing late binding to run AdvancedSearch in Outlook in .NET8?
I'm trying to use the AdvancedSearch feature from Outlook in my .NET 8 application, but I haven't been able to make it work. I'm currently using Restrict when I need to filter by a specific sender or by date. However, I need more advanced filtering options — for example, checking if the subject contains a specific word. I could use a loop to do this after retrieving the results with Restrict, but it's very slow. It seems like AdvancedSearch would be a better option, but I'm getting an error when I try to run the search. Below is an example of my code, although I've tried many variations. If anyone can share a working example, that would be really helpful. Thanks in advance! string searchTag = "BuscaOutlook"; string searchScope = "'\\Caixa de Entrada'"; filter = "@SQL=\"urn:schemas:httpmail:subject\" LIKE '%orcamento%' AND \"urn:schemas:httpmail:datereceived\" >= '2024-04-01 00:00:00'"; try { dynamic searchb = outlookApp.AdvancedSearch(searchScope, filter, true, searchTag); } catch (Exception ex) { MessageBox.Show("Erro no AdvancedSearch:\n" + ex.Message); return; }
