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!System.Text.Json Source Generators Makes Serialization 40% Faster in ASP.NET!
In this video I looked at how to use Source Generators with System.Text.Json to improve serialization and deserialization performance by up to 40%. We then looked at how we can use this in an ASP.NET application. https://www.youtube.com/watch?v=sRCAwmF2arY
.NET 8.0.2 Update Causes ASP.NET Core MVC 'Index View Not Found' Error
Hello everyone, I recently updated to .NET https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.2/8.0.2.md?WT.mc_id=dotnet-35129-website and encountered an issue with my ASP.NET Core MVC application. After the update, the application began throwing an error related to the 'Index' view not being found. This issue was not present prior to the update. An unhandled exception has occurred while executing the request. System.InvalidOperationException: The view 'Index' was not found. The following locations were searched: /Views/Home/Index.cshtml /Views/Shared/Index.cshtml This error is generated by the Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware and specifically indicates that the MVC framework is unable to locate the 'Index.cshtml' file in both the 'Home' and 'Shared' directories, where it traditionally searches for views. I've verified the existence of the 'Index.cshtml' file in the correct location and ensured that the routing configurations are set up correctly. This setup was working seamlessly before the update to .NET 8.0.2. Update: I was able to resolve this issue by uninstalling the .NET 8.0.2 updates. After reverting to the previous version, the application started working as expected without any errors. It appears that the .NET 8.0.2 update may have introduced a change or incompatibility affecting the way ASP.NET Core MVC applications locate views.Wont install Framework ect automaticly ???
I have an app/program (an EXE-file) I made way back when King of Spade was a Knight and I've used it for years on Windows 10 where it automaticly downloaded and installed the dependencies ! Now I run it under Windows 11 ... it just DON'T ! I know I SHOULD go back and make an "install package" but isn't there a 'Work-Around' ?Using 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; }
[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.

Upgrade guide .net framework 4.5 to 4.8
Hello! We are in the process of upgrading .net framework version from 4.5 to 4.8 for a legacy application. We have class library projects, web forms project and an MVC project. 1. The system.* assemblies for some of the projects in the the .csproject file look like below. I don't think these are installed as nuget packages. instead, i believe these are added as reference from the GAC. is this assumption correct? If so, as part of the upgrade process, should i remove these assembly references and install them as nuget packages instead or shall i keep the assemblies as they are? <Reference Include="System" /> <Reference Include="System.Data" /> <Reference Include="System.Data.DataSetExtensions" /> <Reference Include="System.Data.Linq"> <RequiredTargetFramework>3.5</RequiredTargetFramework> </Reference> <Reference Include="System.Web.ApplicationServices" /> <Reference Include="System.Web.DynamicData" /> <Reference Include="System.Web.Entity" /> <Reference Include="System.Drawing" /> <Reference Include="System.Web" /> <Reference Include="System.Web.Extensions" /> <Reference Include="System.Xml" /> <Reference Include="System.Configuration" /> <Reference Include="System.Web.Services" /> <Reference Include="System.EnterpriseServices" /> <Reference Include="System.Web.Mobile" /> <Reference Include="System.Xml.Linq" /> 2. How do i determine should i need to use a newer version of the assemblies than the current ones while upgrading to framework 4.8? 3. Here is the collective list of all the System.* assemblies that are referenced in the projects in the solution System System.Core System.Xml.Linq System.Data.DataSetExtensions System.Data System.Xml System.configuration System.Data.Linq System.Web System.Web.ApplicationServices System.Web.DynamicData System.Web.Entity System.Drawing System.Web.Extensions System.Web.Services System.EnterpriseServices System.Web.Mobile
