Several (currently only one) custom TypeDescriptor implementations for .NET Framework.
Use build.cmd to restore Nuget packages, build project and run unit tests with NUnit.
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);
