UI Path bug (IMHO)

if you invoke a file and the path is wrong no error will be raised

specified element is already the logical child of another element-disconnect it first

close and reopen

nullable int which is key in dapper and getting casting errors?

do this

[ExplicitKey]
        [Computed]

see why POST data is null

 public int SaveBlah([FromBody] Object blah)
        {
             var jsonString = blah.ToString();
             Blah result = JsonConvert.DeserializeObject<B;ah>(jsonString);
}

VS Project wont go in debug - no compile errors on VS

run dotnet run project file name at the root folder
now you will see the error

Access to the path errors

delete bin and obj folders
make sure you are running as Admin

get request info in c# from RequestMessage

response.RequestMessage.Content.ReadAsStringAsync().Result
