Copy RemoteDebugger to remote machine from your local Visual Studio directory (This is path for VS2010) C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Remote Debugger Start remote debugging monitor on the server ‘msvsmon.exe’ Go to Tools/Options and select ‘No Authentication (native only)’ and ‘Allow any user to debug’ In your Visual Studio select ‘Debug/Attach to Process’ , specify Transport as ‘Remote (Native only with no authentication)’ and put your server name as Qualifier, click Refresh and you should see the list of processes on the remote machine. Select the process you want to debug and click ‘Attach’

Left outer join extension method is based on How to: Perform Left Outer Joins article. [Test] public void Test() { var list1 = new List< int >() { 1, 2, 3, 4, 5}.Select(x=> new {a=x, b=x*x}); var list2 = new List< int >() { 1, 2, 3, 4 }.Select(x => new { a = x, b = x * x * x }); var innerJoin = list1.Join(list2, x => x.a, y => y.a, (x, y) => new {a = x.a, b = x.b, c = y.b}); innerJoin.ForEach(Console.WriteLine); var leftOuterJoin = list1.LeftOuterJoin(list2, x => x.a, y => y.a, (x, y) => new { a = x.a, b = x.b, c = (y != null ) ? y.b : ( int ?) null }); leftOuterJoin.ForEach(Console.WriteLine); } public static class Extensions { public static IEnumerable<TResult> LeftOuterJoin<TOuter, TInner, TKey, TResult>( this IEnumerable<TOuter> outer, IEnumerable<TInner> inner, Func<TOuter, TKey> outerKeySelector, Func<TInner, TKey> innerKeySelector, Func<TOute...

To allow your 32bit application use more than 2GB of RAM you need to modify the *.exe file with editbin utility. (open ‘Visual Studio Command Prompt’ and it will be on the path) editbin /LARGEADDRESSAWARE <your-app.exe> or just add these 2 lines to your Post-build event in Visual Studio call "$(DevEnvDir)..\tools\vsvars32.bat" editbin /LARGEADDRESSAWARE "$(TargetPath)" or these if you are building your project with msbuild outside of Visual Studio call "%VS100COMNTOOLS%\vsvars32.bat" editbin /LARGEADDRESSAWARE "$(TargetPath)" To check if all ok run dumpbin utility as below and check if the output has ‘Application can handle large (>2GB) addresses’ text in FILE HEADER VALUES. dumpbin /headers <your-app.exe>
