copied!<p>In your binding configuration, there are four timeout values you can tweak:</p> <pre><code><bindings> <basicHttpBinding> <binding name="IncreasedTimeout" sendTimeout="00:25:00"> </binding> </basicHttpBinding> </code></pre> <p>The most important is the <code>sendTimeout</code>, which says how long the client will wait for a response from your WCF service. You can specify <code>hours:minutes:seconds</code> in your settings - in my sample, I set the timeout to 25 minutes.</p> <p>The <code>openTimeout</code> as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the <code>closeTimeout</code> is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.</p> <p>The <code>receiveTimeout</code> is a bit like a mirror for the <code>sendTimeout</code> - while the send timeout is the amount of time you'll wait for a response from the server, the <code>receiveTimeout</code> is the amount of time you'll give you client to receive and process the response from the server.</p> <p>In case you're send back and forth "normal" messages, both can be pretty short - especially the <code>receiveTimeout</code>, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.</p> <p>There's also openTimeout, receiveTimeout, and closeTimeout. The <a href="http://msdn.microsoft.com/en-us/library/system.servicemodel.channels.binding_members.aspx" rel="noreferrer">MSDN docs on binding</a> gives you more information on what these are for.</p> <p>To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "<a href="https://rads.stackoverflow.com/amzn/click/0596101627" rel="noreferrer">Learning WCF</a>" book by Michele Leroux Bustamante:</p> <p><a href="http://ecx.images-amazon.com/images/I/51GNuqUJq%2BL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg" rel="noreferrer">Learning WCF http://ecx.images-amazon.com/images/I/51GNuqUJq%2BL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg</a></p> <p>and you also spend some time watching her 15-part "<a href="http://www.dasblonde.net/WCFWebcastSeries.aspx" rel="noreferrer">WCF Top to Bottom</a>" screencast series - highly recommended!</p> <p>For more advanced topics I recommend that you check out Juwal Lowy's <a href="https://rads.stackoverflow.com/amzn/click/0596521308" rel="noreferrer">Programming WCF</a> Services book.</p> <p><a href="http://ecx.images-amazon.com/images/I/41odWcLoGAL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg" rel="noreferrer">Programming WCF http://ecx.images-amazon.com/images/I/41odWcLoGAL._BO2,204,203,200_PIsitb-sticker-arrow-click,TopRight,35,-76_AA240_SH20_OU01_.jpg</a></p>
