Hi Leonard Zuluaga,

Thanks for reaching out to us on Microsoft Q&A forum.

Does the Entity Framework Core you mentioned refer to this Nuget package? I can install it in Visual Studio, can you provide more information?

Update: What package source did you choose? Did you choose nuget.org? Please make sure you have selected the correct package source, you can upload a screenshot of the nuget solution manager.

Update:

If your Visual Studio package source does not have nuget.org, you can try to add it to the package source. Name: nuget.org Source: https://api.nuget.org/v3/index.json

Hi Leonard Zuluaga,

Thanks for reaching out to us on Microsoft Q&A forum.

Please open Visual Studio > Tools > NuGet Package Manager > Package Manager Settings > Package Sources > check if any invalid package sources are still list there, if so try to remove them or uncheck them, and make sure that the valid package source like nuget.org is checked, then retry installing NuGet package.

Besides, you may need to try to clean NuGet cache, see this document for details: Clearing local folders.

Check Dependencies: Ensure that your project’s dependencies are correctly specified in your .csproj or .fsproj files. Sometimes missing or incorrect dependencies can cause NuGet restore failures.

2.    Clean and Rebuild: Try cleaning your solution and then rebuilding it. Sometimes cached files or outdated build artifacts can cause issues.

3.    Check Package Sources: Verify that your NuGet package sources are correctly configured. You can do this by opening Visual Studio and going to Tools > Options > NuGet Package Manager > Package Sources. Make sure the necessary package sources are listed and enabled.

4.    Update NuGet Package Manager: Ensure that you’re using the latest version of the NuGet Package Manager. You can update it by going to Tools > Extensions and Updates > Updates > Visual Studio Gallery > NuGet Package Manager.

5.    Check for Package Conflicts: Sometimes conflicting package versions can cause issues. Use the dotnet list package command to check for any conflicts in your project. If you find any, try updating or downgrading the affected packages.

6.    Verify Solution Configuration: Ensure that your solution configuration (Debug/Release) matches the configuration specified in your project files. Mismatched configurations can lead to unexpected behavior.

7.    Check for Invalid Characters: Make sure there are no invalid characters (such as spaces or special characters) in your project or solution paths. These can sometimes cause problems during package restoration.

8.    Inspect the Error Message: Look closely at the error message provided by NuGet. It might contain additional details about what went wrong. If you see any specific package names or paths mentioned, investigate those further.

Remember to try these steps one by one and test after each change. If none of these solutions resolve the issue, please provide more details about the error message you’re encountering, and I’ll be happy to assist further!
