is access via HTTP to MDrivenServer disabled in new releases of MDrivenServer? Even if I setup correct WebServices_*.config files MDrivenServer always returns System.NullReferenceException: Object reference not set to an instance of an object.

I am not aware that we made such a change.
If you use http for development - consider a self signed cert and use this thing i chrome to skip the hassle of getting everything right :

I have been trying to add an environment resource to our pipeline in azure devops but every time i install it with the powershell script they provide it asks me for tags. If i don't want to input tags it errors. If i choose to put in tags it errors. Either way it starts over every time and it will never successfully install. Anyone know if this is something on my end or on their end? I looked through the diagnostic file and the exceptions it is logging look like it's something that i can't fix but i have been having issues with this for over a week and thinking it was something that Microsoft would realize and patch. Now i'm wondering if there is something else i can do?

I was experiencing a similar error "Failed to add virtual machine resource. Linked environment pool is null."
Answer from Kevin Ross here: https://developercommunity.visualstudio.com/t/addition-of-resource-to-environment-fails-for-user/1048111
I resolved my error by following the below steps:
Get the deployment pool ID from the environment URL
Find the deployment pool settings in the organization settings and navigate to the correct pool based on ID from step 1
From the deployment pool settings, go to security and add the required user to administrator role or whatever role is required
I have a problem with a running build machine, where the agent suddenly does not want to start. It's been a part of a remote controller and for trouble shooting this issue, if started a local controller. The symptoms are, at the agent(s) initializes correct (says 'Ready'), but has the stopped icon and in the status area says 'BuildController has not been started in 1 minutes. The AD account running the build service works on another build machine (seperate controller + build agents). I've tried the following
Reinstall the build service
running with machine name, fully qualified domain name and IP address for endpoint address
un- and re-registered build service
rebooted
cleaned up build agent registrations with script
If I change the service account running the build service to my own AD account, it works. However, running under our dedicated build user failes on this particular machine, but not the other. Any suggestions what to do? Here's the error from the event log:
Service 'Default Agent - tfs2010build1' had an exception:

Found the problem. Proxy server was enabled under IE options. Not sure why the build service worked under my AD user account and not the dedicated build user, but it solved the problem.
---->>>>>Update!
So we have 2 machines (B1 & B2), each with 2 agents. B1 had the initial problem and was solved by disabling the proxy settings under IE. Yesterday B2 suddenly started showing the same symptons and error messages on the 2 agents. Proxy setting is NOT enabled. While it did fix B1, it's not the universal solution for this particular problem.
It's hard work keeping these build agents running :( - Miss TeamCity...
---->>>>Update again!
So yesterday when I looked at the proxy configuration, it wasn't set. However this morning the checkbox was checked. Disabled the proxy and the agents went online. Very strange behavior! Wonder if Windows Update changes these settings...
I often get this same issue with the proxy when I am forced to manually stop a build. I have not been able to find any decent resolutions for this.
Well, I'm here to ask about some problem I have, the detail is that when I publish the application from my computer to the server folder and after make the changes in IIS when I try to browse the web app I get the next error:
Index and length must refer to a location within the string.
Parameter name: length
In my local computer, I installed Visual Studio 2008 with SP1 and in the server is not installed only Framework 3.5.
Is the error related with Entity Framework or it's another problem?
Well, I hope you could help me... regards !

The error thrown is from a substring operation. Where it is actually being thrown, I have no clue, as you have not actually posted the stack trace on the error. This could be because you don't know how to do this?
If you can find the stack trace, or even detail your code that gets pieces of a string, you will have a better context of the exception and be able to start doing something to cure it.
As for root cause, the fact it is only happening after publish indicates a) something is missing on the server or b) the server is configured incorrectly (wrong version of .NET for the app pool for example) or c) you have not correctly published the site (maybe copied from your compiled application rather than published and moved the published version over, etc.???)
All of a sudden, I am consistently getting a weird COMException on this machine when I try serve a web app with IIS. I never used to have any problems with this.
Stack Trace:
[COMException (0x80070006): The handle is invalid. (0x80070006 (E_HANDLE))]

How can I fix this? I need this server to be working later today for a demo.
Things I have tried:
Stop/Start in IIS
aspnet_regiis -i
reboot
It is not actually a COM error, it is a Windows error, wrapped in a COM error code. It is a very low-level error, little can be distilled from the error code or the stack trace. There are plenty of hits when you Google the message, here's one that looks good. Be sure to find more yourself if that's not a good match.
We have a workflow as webservice application. We use custom tracking profile for each workflow type.
The worklfow assembly version got changed, so I changed the profile version too. So as the older workflows should work fine.
Now I started the workflow runtime , a workflow got triggered and persisted to DB
After some time , i re-start the runtime, the workflow is re-hydrated, but try to invoke an event on workflow, it shows exception.
If The workflow engine is not re-started , everything works fine, no errors and workflow is completed.

Any ideas, what is getting wrong? There are two workflows of different versions, but attached to same profile version, can this be issue?
I found the solution for it. The version of tracking profile should match the version while creating tracking profile xml.
TrackingProfile myProfile = new TrackingProfile();
myProfile.Version = new Version("4.0.0.0");
The verison should be same as the version used in stored procedure "UpdateTrackingProfile"
This solved my problem.
