This incident occurred whilst creating a new ASP.NET 4.7.1 project in Visual Studio Enterprise 2017 (Version 15.5.2):
Upon building and running the web application, an error occurred:
Could not load file or assembly ‘System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Here’s the source error:
Line 21: new { controller = “Help”, action = “Index”, apiId = UrlParameter.Optional });
Line 22:
Line 23: HelpPageConfig.Register(GlobalConfiguration.Configuration);
Line 24: }
Line 25: }
And the full stack trace:

After creating a few dummy projects and testing, I determined the adding references to Flurl.Signed / Flurl.Http.Signed and updating packages using the NuGet package manager added the following dependent assembly in the Web.Config file:
<dependentAssembly>
<assemblyIdentity name=”System.Net.Http” publicKeyToken=”b03f5f7f11d50a3a” culture=”neutral” />
<bindingRedirect oldVersion=”0.0.0.0-4.1.0.0″ newVersion=”4.1.0.0″ />
</dependentAssembly>
I understand what’s going on but not how to fix the dependency reference. I did find however that simply removing or commenting out the dependent assembly reference to “System.Net.Http” resolved the issue (at least presumably until another NuGet update is made).
Since I did not have this issue prior to updating Visual Studio 2017 from 15.5.1 to 15.5.2 last week, I’m making an educated guess that was the cause.

Other resources to consult:
This is in addition to a question I answered on Stack Overflow where someone had asked how to turn off IE compatibility mode (hint: set “X-UA-Compatible” to “IE=edge”).
These additional response headers are useful in making ArcGIS Server REST endpoints accessible across sites without adding XSS vulnerability.

Books
“Learn Python the Hard Way, 3rd Edition” is available online for free or you can buy the eBook.
Several Packt Publishing titles also come to mind:
• Learning Python Design Patterns
• Expert Python Programming
• Python Tools for Visual Studio
• Raspberry Pi Cookbook for Python Programmers
• BeagleBone for Secret Agents
• Python for Secret Agents
• Python Programming for Arduino
I would suggest creating an account with them and signing up for their daily special.
Some people don’t like O’Reilly but I find their books are pretty good as well:
• Head First Python
IDE
One thing Python lacks is a solid IDE but that’s changed now that Microsoft has made Visual Studio Community 2013 available for free. Couple this with the Packt title, “Python Tools for Visual Studio“, listed earlier and you have a viable platform.
Some people swear by IDLE; I like Google’s PyScripter myself.
There’s also a great stackoverflow article listing many of the IDEs available and their feature set.
Python 2.x vs 3.x
There’s a war of sorts going on in the Python community since the release of version 3.x which breaks some existing 2.x code. The general consensus is to steer people towards 3.x unless they have to support 2.x legacy code or require a plug-in that’s not supported in 3.x.
Yep, I stole this entry’s title from the support article in the WordPress support forums.
Please do all those iPad owners a favor and disable OnSwipe on your blog. It does nothing to enhance or beautify your blog. In fact, it does the opposite and removes your individualization thus making all WordPress blogs look (and bounce) the same (boring).
