Microsoft.AspNetCore.StaticFiles 2.2.0 is deprecated and will lead to a lot of critical security vulnerability warnings (NU1904)

[gszdev]

Is is possible to remove the dependency to the depracted nuget package 'Microsoft.AspNetCore.StaticFiles' (AspNetCore 2.2, ...)?
And I assume that a FrameworkReference to Microsoft.AspNetCore.App is not wanted for sure.

A least with .NET 9 it will lead to critical security vulnerability warnings (NU1904)

A simple copy of FileExtensionContentTypeProvider.cs should be enough to repace the usage in ObjectTeams.cs new FileExtensionContentTypeProvider().TryGetContentType(photoPath, out contentType);
Or use the MimTypeMap like from PnP.Core PnP.Core/Utilities/MimeTypeMap.cs

But I don't know wether the licensing allows it.

FileExtensionContentTypeProvider.cs
// Licensed to the .NET Foundation under one or more agreements.
// The .NET Foundation licenses this file to you under the MIT license.

Is PnP.Framework part auf the .NET Foundation?

@gszdev : I've removed this dependency (copied over the one class we needed from this old deprecated assembly).
