⬆ Bump OpenTK.Core, OpenTK.Mathematics and OpenTK.Windowing.Desktop - #430

Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/setup-dotnet@v4. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

The type 'TValue' cannot be used as type parameter 'TKey' in the generic type or method 'Dictionary<TKey, TValue>'. Nullability of type argument 'TValue' doesn't match 'notnull' constraint.

Non-nullable property 'Current' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier or declaring the property as nullable.

Cannot convert null literal to non-nullable reference type.

Nullability of reference types in type of parameter 'other' of 'bool AnyAction.Equals(IAction other)' doesn't match implicitly implemented member 'bool IEquatable<IAction>.Equals(IAction other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool BinaryAction.Equals(IAction other)' doesn't match implicitly implemented member 'bool IEquatable<IAction>.Equals(IAction other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool LambdaAction.Equals(IAction other)' doesn't match implicitly implemented member 'bool IEquatable<IAction>.Equals(IAction other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool DummyAction.Equals(IAction other)' doesn't match implicitly implemented member 'bool IEquatable<IAction>.Equals(IAction other)' (possibly because of nullability attributes).

Nullability of reference types in type of parameter 'other' of 'bool DigitalAction.Equals(IAction other)' doesn't match implicitly implemented member 'bool IEquatable<IAction>.Equals(IAction other)' (possibly because of nullability attributes).

The type 'TValue' cannot be used as type parameter 'TKey' in the generic type or method 'Dictionary<TKey, TValue>'. Nullability of type argument 'TValue' doesn't match 'notnull' constraint.

The target framework 'net6.0' is out of support and will not receive security updates in the future. Please refer to https://aka.ms/dotnet-core-support for more information about the support policy.
