CustomTypeDescriptors

Several (currently only one) custom TypeDescriptor implementations for .NET Framework.

Build:

Use build.cmd to restore Nuget packages, build project and run unit tests with NUnit.

Usage:

Given that we have MyModel class that we want to extend:

class MyModel
{
	[DisplayName("First name")]
	[Required]
	public string FirstName { get; set; }

	[StringLength(20, MinimumLength = 5)]
	public string LastName { get; set; }

	[Range(0, 120)]
	public int Age { get; set; }
}

Configure LamdaTypeDescriptor for MyModel implicitly:

// Instantiate configuration
var config = new LambdaDynamicTypeConfiguration<MyModel>();

// configure metadata
config.ForProperty(m => m.LastName).
		.RemoveAttribute(typeof(StringLengthAttribute);

// Add config to provider
var provider = new LambdaTypeDescriptionProvider(new []{ config });
TypeDescriptor.AddProvider(provider);
