I got this error today and was causing me a headache. I stopped all apps running in IIS Express, tried switching releases, etc. But seems like this is a bug in Visual Studio 2019.
Stop your application, close the solution, delete the .vs folder in the solution, open it back up and it should work.
Leave a CommentIf your working with other developers this file should not be ignored within your .gitignore file. Its useful for environmental and other settings.
I’m not sure why the template I downloaded had it ignored. Seems like its been an issue for a while and has been corrected a few times.

Leave a CommentAdding app_offline.htm to the root of your .net application automatically shuts it down. Very nice for putting up a quick maintenance page.

You can use the following access modifiers to specify the accessibility of a type or member when you declare it:
public
The type or member can be accessed by any other code in the same assembly or another assembly that references it.
private
The type or member can be accessed only by code in the same class or struct.
protected
The type or member can be accessed only by code in the same class or struct, or in a class that is derived from that class.
internal
The type or member can be accessed by any code in the same assembly, but not from another assembly.
protected internal
The type or member can be accessed by any code in the assembly in which it is declared, or from within a derived class in another assembly. Access from another assembly must take place within a class declaration that derives from the class in which the protected internal element is declared, and it must take place through an instance of the derived class type.

Leave a CommentThe only way I found to change the HtmlEncode property on a bound column when auto-generating the grid-view.
protected void grFeedHistoryView_RowDataBound(object sender, GridViewRowEventArgs e)
{
BoundField field = (BoundField)((DataControlFieldCell)e.Row.Cells[2]).ContainingField;
field.HtmlEncode = false;

db.Customers.InsertOnSubmit(newCus);
db.SubmitChanges();
//Update a record
Customer record = (from p in db.Customers

Console.WriteLine(default(Customer));

Don’t recall where I found this but converts List to DataTable.
public static System.Data.DataTable ToDataTable<T>(this IList<T> data)
{
System.ComponentModel.PropertyDescriptorCollection props = System.ComponentModel.TypeDescriptor.GetProperties(typeof(T));
System.Data.DataTable table = new System.Data.DataTable();
for (int i = 0; i < props.Count; i++)
{
System.ComponentModel.PropertyDescriptor prop = props[i];
table.Columns.Add(prop.Name);
//table.Columns.Add(prop.Name, prop.PropertyType);
}
object[] values = new object[props.Count];
foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)
{
values[i] = props[i].GetValue(item);
}
table.Rows.Add(values);
}
return table;
}

Pieced this together from stackoverflow… http://stackoverflow.com/questions/2912476/using-c-sharp-to-check-if-string-contains-a-string-in-string-array/2912541#2912541
string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };
This checks if stringToCheck contains any one of substrings from stringArray.
if(stringArray.Any(stringToCheck.Contains))
If you want to ensure that it contains all the substrings, change Any to All:
if(stringArray.All(s => stringToCheck.Contains(s)))

Here is a regular expression for credit card numbers.
string ccRegEx = @"^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\d{3})\d{11})$";

string _usZipRegEx = @"^\d{5}(?:[-\s]\d{4})?$";
string _caZipRegEx = @"^([ABCEGHJKLMNPRSTVXY]\d[ABCEGHJKLMNPRSTVWXYZ])\ {0,1}(\d[ABCEGHJKLMNPRSTVWXYZ]\d)$";
