Backend Code for asp.net and mysql

I need you to develop some software for me. I would like this software to be developed for Windows using asp.net and mysqlAddCustomProperty Creates a new custom field for an asset table, which dynamically extends the asset type to support any fields as needed by the user.  Input Parameters: - TableID: An integer value which references a valid asset table in sys_assettables. - CustomProperties (datatable): Same table properties as in the CreateNewAssetType function. Business Logic - Using the TableID provided, for each row in the CustomProperties datatable add a row to the sys_assettables_properties table, matching the fields that are provided in the datatable with those in the sys_assettables_properties table. - Add a field to the existing AssetNameAsset table schema, extending the default field set created above to include each of the custom properties in the datatable. - Create a system audit log entry to indicate that a new field has been added to the table specified, by whom and at what date/time. Return Value: Upon success the function should return a blank string, indicating success, or in case of error return the error details in a human readable format (something that can just be passed back to the UI and understood by the user).  DeleteCustomProperty Deletes a field from the asset table specified, which also removes all of the data stored in the table within that field.  Input Parameters: - TableID: An integer value which references a valid asset table in sys_assettables. - PropertyName: A string value indicating the property/field to be deleted.  Business Logic: - First, validate that the PropertyName provided is not one of the core fields in our database schema, if it is it cannot be deleted and an error is returned to the user.  If this validation passes: o Delete the field from the sys_assettables_properties table for the TableID specified. o Delete the field from the actual database table. - Create a system audit log entry to indicate that the property was deleted, by whom and at what date/time. Output Format: Upon success the function should return a blank string, indicating success, or in case of error return the error details in a human readable format (something that can just be passed back to the UI and understood by the user).  DeleteAssetType Deletes an entire asset type/structure from the system as a soft-delete, leaving the tables/etc in tact.  Input Parameters: - TableID: An integer value which references a valid asset table in sys_assettables. Business Logic: - Toggles the IsDeleted bit field in the sys_assettables table for the TableID specified. - Create a system audit log entry to indicate that the table was soft-deleted, by whom and at what date/time. Output Format: Upon success the function should return a blank string, indicating success, or in case of error return the error details in a human readable format (something that can just be passed back to the UI and understood by the user).
