Fixed glib source double removal then using Source.Remove (Timeout.Remove, Idle.Remove).
I don't know if fix is correct or safe, but it solves problem that you can test in TimerDemo section from samples.
Repro:
If on Windows you should enable console in samples: <OutputType>Exe</OutputType>
Go to TimerDemo section and press buttons:
1. Add timer
2. Remove timer by handler
3. GC - no error in console
1. Add timer
2. Remove timer
3. GC - error in console "GLib-CRITICAL **: 20:29:41.579: Source ID 123 was not found when attempting to remove it"
Warnings produced complain that re-throw did not properly capture stack trace.
Given that these rethrow just to please compiler, I think it is better fix that.
* Disable loading of additional assemblies in AOT context
AOT does not supports `Assembly.Load` and `Assembly.GetReferencedAssemblies()` when running AOT.
I opt-out of code which try to find type. In AOT context this means that you rely on dynamic type loading and you have issues anyway.
* Fix compilation errors
Idle.Add, Idle.AddSeconds, Timeout.Add, Timeout.AddSeconds methods overloads are generalized:
* no priority (for default priority)
* enum priority (for standard priorities)
* int priority (for custom priority)
* overloads call main method with int priority
Fixed leak in Timeout.Add(priority): method was not using userData and DestroyHelper.NotifyHandler.
* Fixed marshaling for reading child properties.
* Enabled child properties for Box, Grid, Stack in api xml.
* Added sample/test for using child properties (ChildPropertiesSection).
Spinner was not spining - should use SetValue, not SetValues.
Also fixed sln - VS2019 not want to open sln by double click in explorer - added empty line.
Also fixed sample project - VS2019 not showing all sources.
This matches the other saving-related methods for Gdk.Pixbuf
- `gdk_pixbuf_save_to_stream` was skipped for the auto-generated bindings (with the warning "Ellipsis parameter: hide and bind manually")
- `gdk_pixbuf_save_to_streamv` was in the generated bindings, but incorrect: the `option_keys` and `option_values` arguments had type `string` rather than `string[]`
* Update to .NET 6
I update not only samples, but also codegen tools, because .NET 5 is not LTS and in 4 month would be out
Closes#306
* Add .NET 6.0 support to actual templates
* Dont forget about FSharp and VB.NET
* Revert choice option in parameters
Some GValue types support null value but code was not checking for .NET "null" and get null ref exception. Fixed nulls for g_value_set_variant, g_value_set_object, g_value_set_boxed as in GLib docs.
This fixes NodeView with null pixbuf column.
