My unit tests disappear from TestExplorer of visual Studio 2019 16.3.5

The output from test engine is:

All projects in the solution are build under framework 4.8 All have Any Cpu as Platform Target. Not as 32-bit prefer option active. I have x64 arquitecture selected for tests. There is no testFile settings in use.

I try rebuild, clean rebuild, resinstall VS, nothing work. I can't find out what this error is.

Constance answered 16/10, 2019 at 18:1 Comment(6)

Many posts point as solution to reinstall .net framework 4.8. It didn't work for me. I went back to version 16.2. The framework can be downloaded from here. learn.microsoft.com/en-us/visualstudio/releases/2019/history . Still waiting for a solution to move forward. – Constance 18/10, 2019 at 13:51

Is being investigated developercommunity.visualstudio.com/content/problem/594971/… – Constance 18/10, 2019 at 22:26

I have the same problem. I moved from 2017 to 2019 and now suddenly I can't use TestMethods and the test explorer is empty. I've been looking for a solution for a few days now. – Subjacent 31/10, 2019 at 9:44

The problem disappear for me. My version is still 16.2 and i can't figure out what changed. I suspect that was some port conflict that prevented the service to start. What ever the problem was, before it disappears, it survive downgrade and reboot. – Constance 31/10, 2019 at 14:6

I just went back to VS 2017 quickly after upgrading to VS 2019. Seems like VS 2019 has a lot of weird and quirky issues. – Subjacent 31/10, 2019 at 14:12

Just upgraded from VS 2022 v17.8.3 to 17.8.4, and this error has resurfaced. – Villainous 10/1 at 20:25

Microsoft recognized the problem and roll out a fix in version VS 2019 16.5.2.

It is available now as VS 2019 16.5.2 Preview 2

Constance answered 11/2, 2020 at 10:19 Comment(7)

In my case just updating to 16.4.5 (current release version) was enough. – Rudderhead 21/2, 2020 at 7:52

This error has been around and can occur for many reasons. Check other posts for possible solutions. Note that the once it happens, you will have to restart VS. I causes some process to crash. Look for visual studio logs for more information about the crash. – Constance 26/4, 2020 at 22:37

16.6.0 and restarting visual studio and restarting my machine is not working – Dashiell 27/5, 2020 at 9:3

16.8.3, up to date, still pops up every time i restart VS. – Dynamic 10/1, 2021 at 22:46

16.10.3 on VS 2019 still happening. – Mckibben 14/7, 2021 at 15:34

There are many reasons why tests won't show. Check if the test engine is running and check the test engine log for clues. – Constance 14/7, 2021 at 16:20

I've VS 2022 and the same error. – Tracay 13/11, 2022 at 6:10

I had a similar issue workaround try this command in the in run window "devenv /ResetSettings", It worked for me.

I had this issue in Visual Studio Enterprise 2019 Version 16.5.4, but restarting VS fixed it.

I fixed this by running Visual Studio as an administrator.

Fixed by closing and opening VS.

Everything worked (VS2019) and suddenly started failing with a similar (did not compare word to word) callstack. Rebuilding did not help, neither did manually killing hung processes from test console. After re-opening VS - everything back to normal

I had the same problem when running Visual Studio 2019
You can type this statement in the run window
"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\devenv.exe /NoSplash /ResetSettings General /Command Exit"
Note, first enter the address of the executable file of the desired version
It is going to be alright

Just had the same on VS2022. Closed VS, deleted the bin folder of the project, re-opened it in VS, ran it and it all worked fine after that.

This error appeared for me whenever I tried to start Visual Studio 2022, after upgrading to version 17.8.4; I would get this error in a pop-up, and then it would disappear. Turns out it was related to a bad binding for System.Numerics.Vector inside of something called the IdentityService. Adding a binding redirect to Microsoft.Developer.IdentityService.exe.config to look for version 4.1.4 instead of 4.1.3 of System.Numerics.Vector fixed it for me:

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
        <assemblyIdentity name="System.Numerics.Vectors" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
        <bindingRedirect oldVersion="0.0.0.0-4.1.4.0" newVersion="4.1.4.0" />
    </dependentAssembly>
</assemblyBinding>

Faced this issue in following version. Clean and Rebuild Solution worked for me. Microsoft Visual Studio Community 2019 Version 16.6.3
