I just recently downloaded 4.2.1 and I’m having problems with multiple .net
projects that make DB queries. This all came up when I got the Xamarin 5.10
upgrade, which wouldn’t run on my OS, so I’m not sure what else could be
contributing to this issue, but all of this code runs fine under 4.0.5. Just
looking for some anecdotal evidence of issues right now.
Here is the kind of errors I am seeing. This is just a call to an sql stored
procedure and the code is pretty simple:
DataSet ds = new DataSet ();
// Issue Query
using (SqlCommand sqlcmd = new SqlCommand(sSqlCommand,
dbConn))
{
SqlDataAdapter sqlda = new
SqlDataAdapter(sqlcmd);
// Set Query Timeout
sqlcmd.CommandTimeout = 900;
// Fill the dataset
sqlda.Fill(ds);
}
