Prevents ending up with an empty C# menu.
The option to create the C# solution no longer disappears, to avoid confusing users.
If an user tries to use it when a C# solution already exists they are warned that it will override their sln and csproj files.
The solution directory used to be the same as the project
directory (`res://`). We now allow specifying a different
path for the solution and the other external editors already
use that (which seems more convenient for multi-project
scenarios).
This commit replaces most usages of `ConvertManagedObjectToVariant` and
`ConvertVariantToManagedObjectOfType`, by using the `Godot.Variant`
struct instead of `System.Object`.
The most notable change is to the `GetGodotPropertyDefaultValues` method
that's generated for scripts. The dictionary it returns now stores
`Godot.Variant` values.
Remaining usages are:
- The `DelegateUtils` class, for the serialization of closure display
classes during assembly reloading by the editor. These display classes
are compiler generated classes to store values captured by a closure.
Since it's generated by the compiler, the only way we have to access
the fields is through reflection. This leads to using `System.Object`.
- Converting parameters when invoking constructors from the engine.
This will be replaced with source generators in the future.
- Legacy support for old `GetGodotPropertyDefaultValues` return values.
We need to keep supporting the old version of this generated method
for some time. Otherwise, if loading a project built with the previous
version, it could lead to the loss of exported property values.
Ideally, we should remove this legacy support before a stable release.
- Creates a `Godot.Offline.Config` file to configurate NuGet with
Godot's fallback folder. This is easier because now we can assume we can
override the entire file since user config will likely be in the default
`NuGet.Config` file or an additional `*.config` file.
- Ensure the NuGet fallback folder is created at the same time it is
added to the NuGet configuration so future builds don't fail.
- Add `GodotSharp` and `GodotSharpEditor` packages to the fallback folder.
- Add `.nupkg.metadata` file to packages in fallback folder.
- Refer to `Godot.SourceGenerators` using the specific non-floating version
since floating versions don't seem to work with fallbackPackageFolders.
When the C# bindings generator finds a type without meta assume the type
refers to the 64-bit version of the type:
- `float` is converted to `double`
- `int` is converted to `long`
- Fix platform detection after Linux OS name was renamed from `LinuxBSD`
to `Linux`
- Fix arch detection after renaming `64` to `x86_64`
- Fix typo in `find_hostfxr`
- Replace `IndexOutOfRangeException` with `ArgumentOutOfRangeException`
- Replace `Exception` with a more specific exception
- Add the parameter name to argument exception
- Update documentation for methods that throw exceptions
- Use `StringBuilder` to build exception messages
- Ensure exception messages end with a period
- Moves interop functions to UnmanagedCallbacks struct that
contains the function pointers and is passed to C#.
- Implements UnmanagedCallbacksGenerator, a C# source generator that
generates the UnmanagedCallbacks struct in C# and the body for the
NativeFuncs methods (their implementation just calls the function
pointer in the UnmanagedCallbacks). The generated methods are needed
because .NET pins byref parameters of native calls, even if they are
'ref struct's, which don't need pinning. The generated methods use
`Unsafe.AsPointer` so that we can benefit from byref parameters
without suffering overhead of pinning.

The setting is initially assigned the name of the Godot project,
but it's kept freezed to prevent issues when renaming the Godot
project.
The user can always rename the C# project and solution manually and
change the setting to the new name.
This new version does not support the following type arguments:
- Generic types
- Array of Godot Object (Godot.Object[]) or derived types
The new implementation uses delegate pointers to call the Variant
conversion methods. We do type checking only once in the static
constructor to get the conversion delegates.
Now, we no longer need to do type checking every time, and we no
longer have to box value types.
This is the best implementation I could come up with, as C# generics
don't support anything similar to C++ template specializations.
- Array and Dictionary now store `Variant` instead of `System.Object`.
- Removed generic Array and Dictionary.
They cause too much issues, heavily relying on reflection and
very limited by the lack of a generic specialization.
- Removed support for non-Godot collections.
Support for them also relied heavily on reflection for marshaling.
Support for them will likely be re-introduced in the future, but
it will have to rely on source generators instead of reflection.
- Reduced our use of reflection.
The remaining usages will be moved to source generators soon.
The only usage that I'm not sure yet how to replace is dynamic
invocation of delegates.
