Easy way to generate “System.InvalidOperationException: Nullable object must have a value.”.
| using System; | |
| public class Test | |
| { | |
| public static void Main() | |
| { | |
| int? nullableInt = null; | |
| int nowInt = (int)nullableInt; | |
| } | |

Every once in a while I do Command-line Building With csc.exe.
When building libraries, it throws this error:
The reason is that by default it wants to build a program.
Change this default by adding the /target:library parameter.

The below batch file finds and runs the latest vsvars32.bat on a system.
vsvars32.bat initializes the path and other environment variables to run Visual Studio and command-line tools (like csc.exe, xsd.exe, editbin.exe).
The batch file employs a few tricks from:

I’m using these Chrome Extensions for most of the http / https call mockups, and after that put them in SoapUI (which despite the name also does REST and has come a long way sinceSource: SoupUI – as sometimes that is the only thing that works):
You can get both Postman versions through GetPostman.com as well.

Boy, don’t you dislike how hard it is to find direct download links…
Well, thanks to kenorb and jjlin (slightly edited):
Check: IE6, IE7, IE8, IE9, IE10, IE11 Offline Installers Download Links – kenorb Mar 20 ’15 at 13:39 – http://www.itechtics.com/download-internet-explorer-all-versions/ – note this does not provide hashes.
Try these Microsoft offline installer links:
- Internet Explorer 10 (32-bit Windows) – http://download.microsoft.com/download/8/A/C/8AC7C482-BC74-492E-B978-7ED04900CEDE/IE10-Windows6.1-x86-en-us.exe
- Internet Explorer 10 (64-bit Windows) – http://download.microsoft.com/download/C/E/0/CE0AB8AE-E6B7-43F7-9290-F8EB0EA54FB5/IE10-Windows6.1-x64-en-us.exe
These may refuse to work if you already have IE 11 installed, though. If it is refused, try this: http://stackoverflow.com/questions/20043971/how-to-downgrade-from-internet-explorer-11-to-internet-explorer-10
And in case these links ever stop working and you must obtain a copy from a non-Microsoft source, here are the SHA-512 hashes for posterity:

HTTP Error 404.0 – Not Found
Had this on a fresh Bonobo Git Server on a relatively fresh Windows 7 installation:
At first I thought it was missing ASP because of the “StaticFile” in the error information, so I enabled it:
ASP is not enabled by default
Enable ASP
That didn’t help, so I searched for “MapRequestHandler” “HTTP Error 404.0 – Not Found” and found:
Though ASP.NET was clearly enabled according to the Windows features, this was apparently for an old ASP.NET version so I manually re-registered ASP.NET (but now for Version 4: I had 4.6.1 installed):
C:\Windows\System32>%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir Microsoft (R) ASP.NET RegIIS version 4.0.30319.0 Administration utility to install and uninstall ASP.NET on the local machine. Copyright (C) Microsoft Corporation. All rights reserved. Start installing ASP.NET (4.0.30319.0) without changing existing web applications to use this version of ASP.Net. ..... Finished installing ASP.NET (4.0.30319.0) without changing existing web applications to use this version of ASP.Net.
Then it still didn’t work, but the second tip above also mentioned the application pool. And since Bonobo insists installing in wwwwroot, it’s using the default application which on Windows 7 – surprise! – is ASP.NET 2.0:
Default Windows 7 application pool for wwwroot uses ASP.NET 2.0
ASP.NET 4.0 needs to be the default.
Changing that to ASP.NET 4.0 made it all work.
Too bad that ASP.NET registration part is only prominently visible in the readme.md on github, but not in the installation instructions of the web-site with a tiny link (overwhelmed by the screenshots) to prerequisites.
Same for the default credentials:

Visual Studio 2015 install stuck on “acquiring” KB2999226
I had exactly the same when installing Visual Studio 2015 on a Windows 7 x64 system: stuck on “Acquiring” the “Update for Microsoft Windows (KB2999226)”.
So as mentioned in the StackOverflow answers for the below question, I manually downloaded “Update for Windows 7 for x64-based Systems (KB2999226)” which you can get directly at https://download.microsoft.com/download/1/1/5/11565A9A-EA09-4F0A-A57E-520D5D138140/Windows6.1-KB2999226-x64.msu.
Be sure to quit both the Visual Studio 2015 installation as well as any (“automagically interfering” background Windows Updates), as otherwise you get this error:
--------------------------- Windows Update Standalone Installer --------------------------- Only one instance of wusa.exe is allowed to run. --------------------------- OK ---------------------------
If you still get that error, then
wuauserv service: usually it gets rid of the error.Applying the KB can take a long while, even on fast hardware.

Direct Microsoft download URLs for the various Visual Studio 2015 Update 2 ISO files.
I won’t even try myself finding them through the Microsoft sites any more given the trouble I had: How can I get Win10_1511_1_English_x64.iso or Win10_1511_1_EnglishInternational_x64.iso ? « The Wiert Corner – irregular stream of stuff

Boy I wish I had known this earlier. Like years ago…
In the Solution Explorer:
It is next to the “Project Dependencies” in this image from Sara Ford:
Sara Ford: change “Project Build Order”
In the resulting dialog, you can change the build order within your solution.
This can be very useful when – for various reasons – you cannot have Project Level dependencies for an assembly, but have to have Assembly Reference dependencies for individual assemblies.
At a client I bumped into this, and this dialog was a life saver for us.
Others have used it because some Visual Studio versions miscalculate the dependencies.
