ZeroFormatter: Fastest C# Serializer and Infinitely Fast Deserializer for .NET, .NET Core and Unity

A C# serializer a la Cap’n Proto. Data is not really serialized and deserialized but a data wrapper is generated to dig into byte[] when possible. Deserialization is really quick but an time penalty occures on each access. Really efficient when only a small part of deserialized data are needed. You pay only for what you use.

No DSL (like .proto) is used but serialized type must permit subclassing properties acces. Each property must be virtual and a derived class is dynamically generated under the hood. A pre compiler exists for Unity.

ExtraConstraints help to add generic constraint supported by .Net and not by C#

ExtraConstraints use Fody’s way to add generic contraint:

Your Code

public class Sample
{
    public void MethodWithDelegateConstraint<[DelegateConstraint] T> () {...}

    public void MethodWithTypeDelegateConstraint<[DelegateConstraint(typeof(Func<int>))] T> () {...}

    public void MethodWithEnumConstraint<[EnumConstraint] T>() {...}

    public void MethodWithTypeEnumConstraint<[EnumConstraint(typeof(ConsoleColor))] T>() {...}
} 

What gets compiled

public class Sample
{
    public void MethodWithDelegateConstraint<T>() where T: Delegate {...}

    public void MethodWithTypeDelegateConstraint<T>() where T: Func<int> {...}

    public void MethodWithEnumConstraint<T>() where T: struct, Enum {...}

    public void MethodWithTypeEnumConstraint<T>() where T: struct, ConsoleColor {...}
}

LongPath: a drop-in library to support long paths in .NET

Another library (AlphaFS: a descent System.IO for .Net) for supporting long path in .Net. This one use same API than System.IO to ease integration : peteraritchie/LongPath: drop-in library to support long paths in .NET.

WpfMaterialForms – Schema generated material dialogs in WPF

Bored of creating dialog layout for simple data entry? WpfMaterialForms can generate them from a simple DOM called Schema:

• CaptionSchema for setting caption,
• MultiSchema for multiple schema,
• StringSchema for string value in an editbox ,
• BooleanSchema for … boolean value through a switch,
• IntegerSchema for int value,
• DateSchema, TimeSchema for what is obvious,
• NumberRangeSchema for int value through a slider,
• CommandSchema for command handling (button click for example),
• ProgressSchema for handling progression (including multistep),
• SelectionSchema for selecting into a combobox,
• SelectionSchema for selecting a file through an OpenFileDialog.

Each Schema contains key (internal id), name, description, icon reference/visibility and validation/error mechanism and is in charge of creating its view (Schema acts as DataContext for this UserControl).

Default view exhibits a clear designe based on WPF/MahApps and MaterialDesignThemes.
