• Visual Studio 2008 (Pre-release) Frame.set_Source throws NullReferenceException in RC1

  This happens (consistently, although some URLs seem to be effected more than others) after I opened and closed at least one Window containing a Frame. Each of these windows is created on a separate (STA) thread so that my main UI remains responsive. The Uri that I pass is definitely not null, I suspect that this is some kind of threading issue with the Frame control. After the issue occurs for the first time, it same issue occurs everytime I set the Source property on a Frame, so basically the process can't display any web pages anymore. This is the call stack: System.NullReferenceException occurred Message="Object reference not set to an instance of an object." Source="WindowsBase" StackTrace: at MS.Win3 ...Show All

• .NET Development Microsoft Oracle .NET Data Provider Performance - repeated internal SQL

  Hi, We are noticing several similar SQLs (listed below) which execute many thousands of times per day. The SQL in question does not access any application tables, it accesses the Oracle data dictionary to retrieve metadata, which is essentially static in this context. On one particular day the SQL is issued some 24,024 times, performing 401 million block accesses and consuming 2,080 seconds of CPU. Our concern is that as our transaction rate increases that this SQL may become a performance bottleneck. I'm wondering if there are any configuration settings within ODP or application coding guidelines which may allow the SQLs to be issued once and the results held locally for re-use I have read about connection pooling and statement caching. ...Show All

• Visual C# Generic Multi-Dimensional Arrays Comparison

        Hi,     I need to compare multi-dimensional arrays in a function which takes 2 multi-dim arrays which can be any type(int, double, bool...etc). Comparison is done by Object.Equals() of each value in each index of the arrays. As a result, Generic and  Multi-Dimensional is what I need to combine. Any idea I compare 1 Dimensional-arrays with the below code of mine: public static bool AreArraysEqualByVal<T>( IList <T> src, IList <T> dest) { if (src == null || dest == null ) throw new ArgumentNullException ( "source or destination array is null." ); if (src.Count != dest.Count) { Debug .WriteLine( "Array lengths were not equal." ...Show All

• Visual Studio 2008 (Pre-release) svcutil / wsdl creates duplicate types in the proxy file

  I have a solution that includes several wcf services. Everything works great until I add a new service and include it in the wsdl generation. What happens is that several of my enumerations get listed twice, once as a System.Xml.Serialization.XmlTypeAttribute, and one as a System.Runtime.Serialization.DataContractAttribute. I've included a code example below showing one of my enum types behaving this way. I can't figure out the pattern of way this only happens when this new service is included, and why only some of the enums are duped, and some are not. [System.CodeDom.Compiler.
