I am new in ASP.NET and use VS2017 with .NET Core 2.0 This is ASP.NET-Core -> Empty project with no authorization. I have the following problem: "The function evaluation requires all threads to run" and when click button "evaluate now" in Watch1 in debugg mod, VS response "Evaluation timed out".
This is my C# code but now all
app.MapWhen(req => req.Request.Path.Value == "/cat/add",
catAdd =>
{
catAdd.Run( async (context) =>
{
if (context.Request.Method == HttpMethod.Get)
{
context.Response.Redirect("/cats-add-form.html");
}
else if (context.Request.Method == HttpMethod.Post)
{
var db = context.RequestServices.GetRequiredService<CatsDbContext>();
var formData = context.Request.Form;
var cat = new Cat
{
Name = formData["Name"],
Age = int.Parse(formData["Age"]),
Breed = formData["Breed"],
ImageUrl = formData["ImageUrl"]
};
db.Add(cat);
try
{
await db.SaveChangesAsync();
context.Response.Redirect("/");
}
catch
{
await context.Response.WriteAsync("<h2>Invalid cat data!</h2>");
await context.Response.WriteAsync(@"<href== ""/cat/add"">Back To The Form</a>");
}
}
});
});
The problem is in "formData"
This is HTML
<h1>Add Cat</h1>
<form method="post" action="/cat/add">
<label for="Name">Name:</label>
<input type="text" name="Name" id="Name" />
<br />
<label for="Age">Age:</label>
<input type="number" name="Age" />
<br />
<label for="Bread">Bread:</label>
<input type="text" name="Bread" />
<br />
<label for="ImageUrl">ImageUrl:</label>
<input type="url" name="ImageUrl" />
<br />
<input type="submit" value="Add Cat" />
</form>
I think the problem is: it doesn't take my form data
I also saw this issue in my asp.net core 2 project today. I think there might be a bug related to VS 2017 debugger and asp.net core 2.
When I put my breakpoint beyond that line that has Request.Form, everything works fine.
