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 How do i determine should i need to use a newer version of the assemblies than the current ones while upgrading to framework 4.8? 3.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
Blazor Server Authentication Without EF Core
Hey guys, I'm searching to solve a problem I'm developing a Blazor Web App with server global interactivity and i want to handle the authentication and authorization. I would like to do it with a cookie to make it permanent and secure. The only solution i found is with the external package Blazored or identity with EF core. But i wouldn't use an external package and database The authentication will be done by an external database with api connection. I'm developing we the .net 8 preview.

How to Resolve .NET Runtime Error 1026 after Windows 11 Update
I hope you're doing well. I am a teacher from Mexico and I'm facing a critical issue after a recent Windows 11 update to version 23H2. Ever since the update, I've been encountering a frustrating problem – a .NET Runtime Error 1026. This issue is causing applications to crash shortly after I launch them, making it impossible for me to access Mi Portal. Given that I heavily rely on Windows applications for my teaching tasks – from document editing to publications and printing, including crucial tasks like payslips handling – this situation has left me unable to perform my duties effectively. I understand that many educators are in a similar situation, where Windows OS and Office applications are our lifelines for seamless work. I urgently need a simple and effective solution to overcome this error and restore the functionality of my Windows 11 system. Your expertise and support in troubleshooting this .NET Runtime Error 1026 would be immensely appreciated. If anyone has encountered a similar issue or has successfully resolved it, I would be grateful for your insights. I need guidance or steps you can provide to help me swiftly resolve this issue and continue my teaching job without further disruptions. Warm regards and appreciation
