Need C# and Json expert want

To fix:
• The documentation does not mention what tools I need to run the solution
• HDI schema required properties are not the same in the json compared to the xsd schema. The same applies to the other schemas
• Json schemas for HDI do not match what the endpoint is expecting. The api accepts:

{
"countries": [
{
"$schema": "./HDISchema.json",
"country-hdi-ID": 1,
"country-hdi-rank": 68,
"country-name": "Albania",
"HDI-2010": 0.46,
"HDI-2011": 0.54,
"HDI-2012": 0.42,
"HDI-2013": 0.50,
"HDI-2014": 0.56
}
]
}

Whereas the schema says:

{
"$schema": "./HDISchema.json",
"country-hdi-ID": 1,
"country-hdi-rank": 68,
"country-name": "Albania",
"HDI-2010": 0.46,
"HDI-2011": 0.54,
"HDI-2012": 0.42,
"HDI-2013": 0.50,
"HDI-2014": 0.56
}

Both do not match what the documentation describes on page 8.

• Unfortunately there are no value restrictions in the schemas
• The system starts with no data at all nor is there a guide on how to load initial data.
• The API does not return XML responses when setting the Accept: application/xml header. Apparently it only checks for text/xml

• Json is not validated according to the schema.
• The location header returned after a POST has the wrong identifier, e.g. https://localhost:44313/api/HDI5, it misses a / between HDI and 5
• Posting XML doesn’t work, gives Connection reset
• No graphical visualization present

In order to sucessfully work the solution needs both XML and Json validation in the API and preferably also some graphical visualization.

The existing project will be supplied to you when the job gets accepted.
