I have seen all of the following questions:
NUnit .NET Core running through Resharper
Running NUnit Tests in .NET Core with ReSharper
NUnit TestCaseSource
Despite following all of their advice and having the following lines in all of my
test projects:
<PackageReference Include="NUnit" Version="3.10.1" />
<PackageReference Include="NUnit3TestAdapter" Version="3.10.0" />
<PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.7.2" />
I am still getting the following errors in the Unit Test Explorer window of ReSharper (version 2018.1.2):

These are the newest versions of each of these packages, but I have also tried matching NUnit's version to the TestAdapter's version (3.10.0). The most baffling part of this is that Visual Studio's Test Explorer has no problem running the tests! I would very much like to use ReSharper's explorer to easily run their profiling and coverage tools on my tests.
Moreover, at some point in time ReSharper's test explorer used to work, but I'm not aware of the particular version combination that led to it. This setup still works for basic [Test] style tests and only fails for [TestCaseSource] tests.
ETA: ReSharper is also not running namespace-level setup and tear-down fixtures. Maybe this is part of the problem?
How do I fix this?
This was a bug. JetBrains fixed it in ReSharper 2018.2 EAP 5. It's still finicky, but when it works, it works.

I am fairly new to Prism so I'm sure I am missing something, a registration or maybe a NuGet package, but I'm not sure what it would be. I commented out the Registrations for Popup as I was getting the same error, but referring to Prism.Plugin.Popups.PopupPageNavigationService
As always, thanks for any help!
It looks like you are attempting to navigate to a page called LandingPage, but you haven't told the container what LandingPage is.
Every time you want to create a new view and navigate to it, you need to register it for Navigation inside your App.Xaml.cs file;
containerRegistry.RegisterForNavigation<LandingPage, LandingPageViewModel>();
This line registers the view and its corresponding ViewModel inside the container. Once the container knows about the view, the NavigationService can resolve the view you wish to navigate to using the literal name of the view LandingPage.
Now you can call
await NavigationService.NavigateAsync("LandingPage");
//or
await NavigationService.NavigateAsync("/MainPage/NavigationPage/LandingPage")
NOTE
Prism navigation has a couple of neat tricks built into it. It is Uri based, so every time you navigate to another view, passing the name of the view in the NavigateAsync method will stack the view on top of the others. This means that if you start at the URI NavigationPage/PageA, if you then say NavigateAsync("PageB") you will end up at NavigationPage/PageA/PageB.
Additionally, including the / character at the very beginning of the NavigateAsync argument completely resets the stack. So if you navigate to /PageC from NavigationPage/PageA/PageB, this resets the stack to just PageC
I'm currently having issues with IIS crashing out leaving the following messages in the event log. They're not too helpful in directing me to the actual source of the error but a bit of research suggests this is just a case of spawning tasks but not waiting for the result, when they do eventually complete if the parent process has completed it cannot be associated with the parent thread which causes a null reference exception. Is that correct?
For the most part I have removed or added awaits where this was going on but there are some areas where it is handy. One such example is on session start is memory caching a few details unique to the session, however they're not vital immediately so I spin up a task to do this work but don't await it.
I have added ConfigureAwait(false), is this sufficient to prevent the error in future? It sounds like this will remove the thread switching which I assume will prevent the error.
Task.Run(() =>
{
// Do caching here
}).ConfigureAwait(false);

After a morning of chasing this problem around I eventually discovered there was a path which could allow for the parent to bypass the await creating this problem. A quick refactoring to prevent this solved the problem.
In its most simple form the code causing the problem was along the lines of this:
var getDataTask = getData();
if(some_condition == true) {
return some_object;
}
getDataTask.Wait();
return getDataTask.result;
If some_condition == true the method would return without waiting for getDataTask to complete. Refactoring to stop that fixed it.
I've just noticed that when running an application I periodically get an error message.

Our application uses Enyim memcached and MemcachedProviders and runs in a load balanced environment.
The application does alot of managing of PDF reports and compiling of responses then generating a final report pdf. So we use streams quite a bit.
This problem only appears to affect our management application as we also expose a webservice and I never get the error when looking at the service definition and WSDL.
From looking at the session table in the DB I can see that they are being created but, many of them have null in the SessionItems field and the locked flag set to 1.
The data time stamps seem to correlate to the null buffer error occurances.
Is this a case of a buffer set incorrectly or maxing out?
I'm trying to setup Ninject on my new project and I want to scan assembilies using convetions so that
IFoo
will automatically resolve to
IBar
All the samples and documentation describes using this approach
kernel.Scan(...)
while the Ninject 3 Kernel seems to use .Load instead. If I'm using Load for scanning then how do I configure scanning with conventions?
Edit
I was able to get it working using: https://github.com/ninject/ninject.extensions.conventions/wiki/What-is-configuration-by-convention
However, now I can't get my modules to load. I'm using the code below and getting the error below.
IKernel kernel = new StandardKernel();
kernel.Bind(x => x
.FromAssembliesMatching("Crt.*.dll")
.SelectAllTypes()
.BindAllInterfaces()
);
kernel.Load("*.dll");
return kernel;
Error:
Ninject.ActivationException was unhandled
Message=Error activating ITrainingEngine
More than one matching bindings are available.
Activation path:

Suggestions:
1) Ensure that you have defined a binding for ITrainingEngine only once.

I'm playing around with MonoDev on my mac and wanting to see how well it can run basic ASP.NET applications which I've worked on.
I chose a very basic site, it's got a handful of ASP.NET pages, all of which inherit nested master pages and some ASP.NET AJAX stuff. The project is .NET 2.0 and I have the web.config set appropriately for ASP.NET AJAX 1.0.
Under windows this runs without any dramas and because it's so simple I expected it to "just work" in MonoDev too. The problem is that when I run using the built-in web server for MonoDev I get the following exception:

It seems though that when I remove my ScriptManager from my root master page everything runs fine (well except for the JavaScript which expects it to be there).
Being completely new to Mono & MonoDev I don't really know where to start with debugging other than getting to the point I'm currently at.
I had the same problem when doing some Mono testing and the problem was the scriptmanager was not inside the form runat="server" id="form1" /form tags. Once that was added the NULL exception went away.
