Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: gittools/actions/gitversion/execute@v1.1.1, gittools/actions/gitversion/setup@v1.1.1. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'progress' doesn't match implemented member 'Task<string> IFlickrUpload.ReplacePictureAsync(Stream stream, string fileName, string photoId, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'progress' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'tags' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'description' doesn't match implemented member 'Task<string> IFlickrUpload.UploadPictureAsync(Stream stream, string fileName, string? title = null, string? description = null, string? tags = null, bool isPublic = false, bool isFamily = false, bool isFriend = false, ContentType contentType = ContentType.None, SafetyLevel safetyLevel = SafetyLevel.None, HiddenFromSearch hiddenFromSearch = HiddenFromSearch.None, IProgress<double>? progress = null, CancellationToken cancellationToken = default(CancellationToken))' (possibly because of nullability attributes).

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'y' of 'int CreationTimeComparer.Compare(ICacheItem x, ICacheItem y)' doesn't match implicitly implemented member 'int IComparer<ICacheItem>.Compare(ICacheItem? x, ICacheItem? y)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'x' of 'int CreationTimeComparer.Compare(ICacheItem x, ICacheItem y)' doesn't match implicitly implemented member 'int IComparer<ICacheItem>.Compare(ICacheItem? x, ICacheItem? y)' (possibly because of nullability attributes).
