Missing "Microsoft.CodeAnalysis" in .net 3.1 install on Ubuntu

I have a .net project that runs in windows with VS code with no issues.
I am trying to run the same project in Ubuntu 20.04.2 with VS code. Run trying to run it with F5, I get the errors:
CSC : error CS8032: An instance of analyzer System.Text.Json.SourceGeneration.JsonSourceGenerator cannot be created from /home/one/.nuget/packages/system.text.json/6.0.6/analyzers/dotnet/roslyn3.11/cs/System.Text.Json.SourceGeneration.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=3.11.0.0, Culture=neutral, PublicKeyToken=****'.

It looks like "Microsoft.CodeAnalysis" was missing. So, I installed it with nuget in VS code. I added 'nuget: add package' in VS code to install 'Microsoft.CodeAnalaysis' version 3.11.0.
I have verified it successfully lives on my system:

I still get the errors mentioned above.

Since Windows 10 1709 Update - System.OutOfMemoryException c# .net

My winforms application has been running perfectly until the latest Windows 10 1709 Update and ever since updating my app crashes constantly when running the standalone .exe or in Visual Studio 2017. The app crashses on any machine with the latest 1709 update. As a test, I created a Windows 7 machine and works perfectly and all versions prior to Windows 10 1709 fine.
Its pretty random when I get System.OutOfMemoryException exception = usually however when System.Form.Timer fires or a thread is run (this may be a a clue!).
One thing for sure, I am not out of memory! (32GB with 50% available on my development machine).
I am at a loss what is causing this and have tried the following:
The solution comprises of around 30 C# projects.
-I have updated from .Net 4.6 to 4.6.1 then to 4.7 and 4.7.1
-Updated all Nuget projects.
-Compiled code on Windows 7, ran on Windows 10 (crashes) - it runs fine on Windows 7.
- Ran on Windows 10 Home, Windows 10 Pro (1709). Works fine on older Windows 10!
- Fresh install of Windows 10 Pro with 32GB of RAM (my development machine).
- Disabled timers and threads (only to get exceptions elsewhere).
Roll back the OS is not a solution as I have users that rely on this software running Windows 10. I have been looking at this for the last week without no resolution and hope I can get some good pointers to finally resolve this.
Below are two tracebacks - I have 100s of these tracebacks (via rollbar.com) since I updated to latest 1709:

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

Its turned out the actual issue was .Net WebBrowser Control that was causing massive amount of memory to be used.. I had fice WebBrowser controls open at the same time.. would eat 2GB of RAM! (more if the x32 compiled app didnt crash, x64 lasted much longer!).
Removed them, app only consumes 25MB again!
p.s. changing over to CefSharp to see if this fares better!

Objective_C Exception Thrown when debugging Xamarin C# iOS App

When I go to build and debug my iOS app, the simulator runs but I get an exception thrown and the simulator doesn't open. I'm using Visual Studio for Mac.
The error is:

Edit:
Adding picture.
Info.plist

It seems like no main.storyboard can be found in your project.
Check this
if the Main Interface is Main , check if main.storyboard exsits in your project.
Or you can change it to other viewController.

Okay, the weirdest thing fixed it. I installed an older version of Xarmarin iOS that I got from this page: https://bugzilla.xamarin.com/show_bug.cgi?id=38206
Then when I opened Visual Studio it didn't detect it and had me update it. After updating it, my app was able to debug and the simulator worked fine! Very, very weird!

Xamarin.IOS exception while running ibtool: object cannot be nil (key: family)

I'm getting a weird error while trying to build my solution:
Exception while running ibtool: *** setObjectForKey: object cannot be nil (key: family)
I've googled it but there is no answers to this problem, just questions... Maybe worth mentioning is that I use Visual Studio Community 2015, I got the latest Xcode installed on my Mac and I have a updated iPhone 5s connected to the Mac. The OS on my Mac is El Capitan (10.11.4).
I think this problem mainly comes from my storyboard, at first I got this error when i tried to create a segue for a button between two views. I removed it and it worked as usual, now I got the same error later on in this project and it's not thanks to the segue.
If I exclude my storyboard, I can build the solution without any trouble, but I can't run the app on my iPhone since the storyboard is missing.
Anyone got a clue what the problem might be? Here are the error logs if necessary:

Edit: I removed my second view controller and created a whole new one, this seems to have fixed the problem. Still not sure what was causing the problem, but if anyone knows I would really like to know if this happens agian.
Edit 2: The error came back as soon as I added a button on the other (new) view controller. It also refers to a run time error regarding the button not having a code behind (which I thought was created when you added the button on the storyboard). See the image.
Seems like the code for the button isn't generated properly.
I'm hoping this could be some help for other people who run into this issue. I'm still a bit stuck since I tried to manually copy everything regarding a button (changing it's name of course) from my working view controller to the new one, but I don't seem to get it to work.
I have added following to my ViewControllerCreate.designer.cs:
UIKit.UIButton BtnCreateAccount { get; set; }
void ReleaseDesignerOutlets()
{
if (BtnCreateAccount != null)
{
BtnCreateAccount.Dispose();
BtnCreateAccount = null;
}
}
Any ideas?

i got the same error.
After analyzing the code main.storyboard, I discovered that, in my case, the error jump if a button or other control has something like:
<fontDescription key="fontDescription" name="HelveticaNeue" pointSize="17" />
The family font is the problem, try change to
<fontDescription key="fontDescription" type="system" pointSize="17" /> or just delete de line.

Marcelo

I am not sure the following code may be helpful for you.
internal class CustomUIView : UIView
{
internal CustomUIView(IntPtr value) :base(value)
{
}
}
Example:
UIView view = new CustomUIView(IntPtr.Zero);

The DataSet class has a WriteXml function to write your data to a file, or GetXml to return it as a string. The documentation on MSDN has further explanation of customizing the output to get it to match exactly what you need, if your XML structure differs from your database structure.

I think you can just use:
string xml = yourDataSet.GetXml();
You can read it back into a DataSet using the DataSet method ReadXml.
You can also use the following to get an XmlDataDocument:
System.Xml.XmlDataDocument xmlDoc = new System.Xml.XmlDataDocument(yourDataSet);
