Something really strange is happening. If i place a break point after a certain line of code, when debugging, the debug session stops as if i hit the "Stop" button.
What's really strange is that, if i skip that function altogether, jumping over it, the code does not crash...
I'm using .Net Core 2, running in a fully updated VS For Mac on any VS (windows and Mac), using C# 7.1
heres the code:
var connectionToUse = new SqlConnection(string.Format(str, dbName));
try
{
SqlCommand command = new SqlCommand();
command.Connection = connectionToUse;
command.CommandText = @"SELECT * from myTable";
await connectionToUse.OpenAsync(); //CANT GET PAST THIS LINE HERE
var r1 = await command.ExecuteReaderAsync();
while (await r1.ReadAsync())
{
//MORE CODE
}
r1.Close();
await Task.Delay(15000);
}
catch (Exception ex)
{
//NEVER ENTERS HERE
}
finally
{
if (connectionToUse.State != ConnectionState.Closed)
{
connectionToUse.Close();
}
}
Edit1:
Using .Open(), no async, works perfectly. But the problem moves to the r1.ReadAsync() line...
Edit2:
prior to that code, the following one runs perfectly
private async Task<Dictionary<int, string>> MapDatabases()
{
Dictionary<int, string> databases = new Dictionary<int, string>();
SqlConnection mainConn = new SqlConnection(string.Format(str, "Master"));
SqlCommand command = new SqlCommand();
command.CommandText = "SELECT name,database_id FROM sys.databases WHERE database_id = 5";
command.Connection = mainConn;
try
{
await mainConn.OpenAsync();
SqlDataReader reader = await command.ExecuteReaderAsync();
while (await reader.ReadAsync())
{
databases.Add(reader.GetInt32(1), reader.GetString(0));
}
reader.Close();
mainConn.Close();
}
finally
{
if (mainConn.State != ConnectionState.Closed)
{
mainConn.Close();
}
}
return databases;
}
EDIT3:
Also reproducible on VS 2017 fully updated.
EDIT4:
Apparently theres something wrong with the await statement. I found out that the code will crash in the first subsequent await, no matter where it is
