So, I installed a new Samsung SSD M.3 drive and found it to be much, much slower than it’s predecessor. After much sturm, drang and gnashing of teeth I stumbled across the solution. The key is in the power requirements on all things – basically just change the power profile to “Performance” in the settings and then confirm that PCI-E is set to 100%. After that it is a night and day difference.

As I’ve looked this up three times now I should put the code directly on the blog. Happily Microsoft has done a lot of the plumbing work for you.

You have a Web API controller with an action that looks like this
[System.Web.Http.Route("Ajax/v1.1/PostItemBatch")]
[OutputCache(NoStore = true, Duration = 0)]
[System.Web.Http.HttpPostAttribute]
public bool PostItemBatch(List postItems)
{
using (ApplicationDbContext db = new ApplicationDbContext())
{
foreach (PostItem postItem in postItems)
{
db.PostItems.Add(postItem);
}
db.SaveChanges();
return true;
}
}
Then you can post data to it by the following

List PostItems = new List();
for (int i = 0; i < 11; i++)
{
PostItems.Add(new PostItem(true));
}

HttpClient client = new HttpClient();
HttpResponseMessage response = client.PostAsJsonAsync("http://localhost:56168/Ajax/v1.1/PostPostItemBatch", PostItems).Result;
var test = response.IsSuccessStatusCode;

And there you go!

The root problem seems to be in the version of Newtonsoft.json – if you set it to version 11.0.1 all of the problems magically disappear

There are two things:
1. Just insert this code in the web.release.config

<system.webServer xdt:Transform=”Insert”>
<rewrite>
<rules>
<rule name=”Force HTTPS” enabled=”true”>
<match url=”(.*)” ignoreCase=”false” />
<conditions>
<add input=”{HTTPS}” pattern=”off” />
</conditions>
<action type=”Redirect” url=”https://{HTTP_HOST}/{R:1}” appendQueryString=”true” redirectType=”Permanent” />
</rule>
</rules>
</rewrite>
</system.webServer>

2. Then make sure that the Url Rewrite module is installed in IIS – if that module is not installed you will get perplexing, unhelpful error messages

Just restart the app pool and the problem goes away.

So – you’re getting the following problem

The following error occurred while loading the extended type data file: Microsoft.PowerShell.Core, C:\Windows\SysWOW64\WindowsPowerShell\v1.0\types.ps1xml(3763) : Error in type “System.Management.Automation.FormatViewDefinition”: Exception: The getter method should be public, non void, static, and have one parameter of type PSObject.

For some reason this just started happening after the last Visual Studio 2017 update

Update – 5/29/2018 – make sure to leave VS Code open while you open Visual Studio 2017 – the problem does recur after every restart for some reason.

First – locate devenv.exe.config in the C:\Users\WarHorse\AppData\Local\Microsoft\VisualStudio\15.0_YOURIDENTIFIER directory

Open that file in VS Code
