There are various toolkits and libraries available for .NET developers that can be used to read information from Indian passports or any other passports that comply with the International Civil Aviation Organization (ICAO) standards for Machine Readable Travel Documents (MRTDs).

One of the common ways to read passport information is through OCR (Optical Character Recognition) technology. Here are a few options that .NET developers can consider:
1. PassportEye Library: PassportEye is a Python-based library that offers support for reading passport MRZ data using OCR. Although it's written in Python, it can be used in conjunction with .NET applications through Python.NET or by creating Python bindings.
2. Tesseract OCR: Tesseract is an open-source OCR engine that supports various languages and can be used to extract text from passport images. There are .NET wrappers available for Tesseract, such as TesseractSharp, which can be used to integrate Tesseract OCR functionality into .NET applications.
3. Third-Party SDKs: Some commercial solutions offer SDKs specifically designed for passport scanning and OCR. These SDKs may provide .NET compatibility or APIs that can be used within .NET applications for reading passport information.
When implementing any of these solutions, it's important to ensure compliance with data protection and privacy laws, especially when dealing with sensitive information like passport details. Additionally, it's essential to consider the ICAO standards and requirements for reading and processing passport information to ensure accuracy and legality.

Before integrating any toolkit or library into your application, review their documentation, compatibility, and licensing terms to ensure they meet your project's specific needs and requirements, including support for Indian passport formats.

Yes, there are applications available that can extract details from passports. These applications use Optical Character Recognition (OCR) technology to scan and analyze the text on the passport and extract relevant information such as the passport number, name, date of birth, and expiration date.

In the context of C#, you can leverage existing OCR libraries and APIs to develop your own application for extracting passport details. One popular library is Tesseract, which is an open-source OCR engine that supports multiple languages, including English. You can use the Tesseract library in your C# application to process passport images and extract the required information.

Here's an example of how you can use the Tesseract library in C# to extract passport details:
```
using Tesseract;

public string ExtractPassportDetails(string imagePath)
{
    using (var engine = new TesseractEngine(@"path\to\tessdata", "eng", EngineMode.Default))
    {
        using (var img = Pix.LoadFromFile(imagePath))
        {
            using (var page = engine.Process(img))
            {
                var text = page.GetText();
                return text;
            }
        }
    }
}
```
In the above example, you need to provide the path to the tessdata folder, which contains the language data for Tesseract (in this case, English). You also need to pass the path of the passport image to the ExtractPassportDetails method, which will return the extracted text.

Remember to handle any exceptions that may occur during the OCR process and ensure that the passport images are of good quality for accurate extraction.
