Add ConEmu to your VisualStudio Menu -> Tools -> External:
By copying the line from ConEmu's shell integration to get:
Command: C:\Program Files\ConEmu\ConEmu64.exe
Arguments: "{PowerShell} -cur_console:n"
Initial Directory: $(ProjectDir)
Put this in the Target of a cmd.exe shortcut and optionally set Run to Minimized:
cmd.exe /c "dir ..\StartupDelayedStart\* && Timeout /T 10 && echo 'waiting...' && Timeout /T 30 && for %f in ( ..\StartupDelayedStart\* ) do start "" "%f" "
Adding merge fields to a Word document without adding a datasource to it is not at all obvious when the mail merge button is greyed out. But to use MailMerge programmatically you probably want to do just that.
You can do it—unobviously—via Insert->QuickParts->Field:
Choose MergeField from the list on the left, and then you can type in your merge field name.
More recently, the “Field” button has been promoted (woo) to a top-level citizen of the Insert Ribbon, so now it' s a bit easier to find:
There’s a great Q and Answer at dijkstra-path-finding-in-c-is-15x-slower-than-c-version which starts with C++ code at 2ms vs C# at 38ms; and finishes with C# at 2.8ms.
On similar lines, the solution to this riddle — why-does-net-core-2-0-perform-worse-than-net-framework-4-6-1 — has nothing to do with the framework; it results from the slower performance of 64bit code compared to 32bit.
Which just goes to confirm what you might have suspected;
VMs aren’t that slow; and
For best performance, you have to understand your VM, and your language, and your O/S, and ultimately your CPU.
