iDashboard | 基于Laravel5.3的简单后台权限管理系统，基本的后台权限完成，后续会根据计划来升级后台功能 | Web Framework library

I have a C# WinForms application.

I'm using the Unity Container nuget package to inject my service classes. If I get the service class in the Program.cs and make a call to my web api to authenticate a username and password using odata, it works successfully. If I call Application.Run(myForm), where myForm is a Telerik RadForm, and asynchronously run the same call, the application closes with no exceptions thrown.

I am using Application.ThreadException and registering Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException) but this does not catch anything.

The line that is causing the application to crash is a call to System.Net.Http.HttpClient.PostAsync(). This call is made from within the service class located in a separate .Net Standard 2.0 Class Library. The main application is a .NET Framework 4.7.2 Windows Application and the UI controls are located in a .NET Framework 4.7.2 Class Library. Again, this call is successful if called outside of the Telerik RadForm.

From within the Telerik RadForm I have tried to execute the call using:

• private async void btnLogin_Click(object sender, System.EventArgs e)
• var t = new Thread(() => Runner.DoWork(new Credentials(u, p, CLIENT_ID)))
• An asynchronous call to a static method without using await

I did get a different result when I called LoginAsync(...).Result on the service class. This caused the application to enter a thread lock state, but did not crash the app.

UPDATE:

There are two RadForms; a DashboardForm and a LoginForm. Program.cs launches the Dashboard which checks for an existing Bearer token. If the token does not exist, the Dashboard displays the Login using .ShowDialog() to prevent using the Dashboard until authenticated. The Login then uses the service class described above.

If instead of launching the Dashboard in Program.cs using Application.Run() I launch the Login, the service call to authenticate is successful.

I then tried launching the Login, from the Dashboard in a new thread, but this resulted in the same problem described above.

Why does the System.Net.Http.HttpClient.PostAsync() crash the application (with no exceptions) if it is called from a Form displayed by another Form?

These are loans that have "Matured". I need a Count for loans that are 25 days after their Maturity Date, 45 days, and the Rest. I need to assign a Label for each so I can create an iDashboard Chart.

I'm using a Subquery but I believe the data I need is located in ONE table.

I use a NSwag to generate TypeScript typings and classes for swagger API endpoints. The resulting classes contain a .toJSON() method for each object which gets called when serializing objects to JSON using JSON.stringify().

All works fine when serializing a single object, but when I try to serialize an Array of objects it throws a weird error:
