QUESTION
I'm trying to implement a new web API. This API returns a JSON from HTTP-request. So far I wrote very basic code, but the strange thing is that I get an error using XML template - and I have no idea what to do: This is the call: http://localhost:55643/api/ShipmentsStatus/getShipmentsStatusJSON
The code is here:
...ANSWER
Answered 2021-Jun-15 at 14:39You should use http://localhost:55643/api/ShipmentsStatus/getShipmentsStatusJSON or change [Route("getShipmentsStatusJSON")] to the appropriate API method name

I have an application using ASP.NET Core MVC and an Angular UI framework.
I can run the application in IIS Express Development Environment without issue. When I switch to the IIS Express Production environment or deploy to an IIS host, my index referenced files cannot be read showing a browser error:
Uncaught SyntaxError: Unexpected token '<'
These pages look like they are loading the index page as opposed to the .js or .css files.
Here is a snippet of the underlying runtime.js as it should be loaded into browser, it is not loaded with index.html.

QUESTION
I want to generate a dynamic LINQ expression for filtering only with Date, but my column is a Datetime field in the DB. Due to this the operator "equal" and "not equal" is not working because it is appending some default time to my input and trying to match with the data. If there is any way to Generate a LINQ expression that will compare only date by excluding the time.
This is my code:
...ANSWER
Answered 2021-Jun-15 at 06:18Don't do it; go the route suggested of using a date range instead
Always seek to avoid creating queries that manipulate table data before a comparison is done. Suppose you have a table with ten million datetimes in, and they're all indexed
The database will probably use the index for this:

QUESTION
I'm trying to validate some JSON files on VB.net. However, Whenever I run my code it gets stuck on
Dim Schema As JsonSchema = JsonSchema.Parse(SchemaString)
The Error Says
An unhandled exception of type 'Newtonsoft.Json.JsonException' occurred in Newtonsoft.Json.dll.
There is also a warning that says that JSON validation moved to its own package. So, I'm pretty sure I'm just importing the wrong packages, but I'm not sure.
I would be grateful if anyone could point me in the correct direction,
Thank you.
Here is my VB.net code
...ANSWER
Answered 2021-Jun-12 at 03:42$schema is only valid at the root, and properties values MUST be schemas.
You have a "$schema" : "#" inside properties. This means that you're trying to say that your JSON object should have a property called schema that can validate against the schema #. But # isn't a valid schema object, so the parse fails.
You need to remove the $schema from your properties.
I'd also suggest using a later draft of the schema spec (if you have control over the schema). Draft 6 is the oldest version that's compatible with the latest, 2020-12.
But for this you'll likely need to use a different validation package. There are several available. Mine is JsonSchema.Net.

We would like SwaggerUI, which is being generated by Swashbuckle, to show all controllers and methods when debugging as well as on our test environment, but hide some on integration and production environments. Note that the hidden controllers/methods will be functional in all scenarios but won't be documented in SwaggerUI.
To do this I've applied the principal described here.

I'm very new to C# and Linq so please forgive if I misuse terminology. As I tried to phrase in my title I would like to supply a Linq query with a List and have it return a List of objects who have a property that is also a List. The query should look at the property of the objects and return the objects whose lists contain all the values of the query list. Here's a simplified example I'm trying to set up in a command line app.

I have been trying to update a record in the database in window form but each time I click the update button I get this error.
System.Data.Entity.Infrastructure.DbUpdateException: 'An error occurred while updating the entries. See the inner exception for details.' SqlException: Violation of PRIMARY KEY constraint 'PK_ad_gb_rsm'. Cannot insert duplicate key in object 'dbo.ad_gb_rsm'. The duplicate key value is (100001). The statement has been terminated.
Below is the LINQ code I am using

Answered 2021-Jun-11 at 11:11The inner exception says everything:
SqlException: Violation of PRIMARY KEY constraint 'PK_ad_gb_rsm'. Cannot insert duplicate key in object 'dbo.ad_gb_rsm'. The duplicate key value is (100001)
Your code tried to perform an INSERT operation, but failed because it violates the unique constraint of the primary key.
