In Visual Studio 2019 (and 2022), you can find this global setting in:

&lt;kbd&gt;Tools&lt;/kbd&gt; &gt; &lt;kbd&gt;Options&lt;/kbd&gt; &gt; &lt;kbd&gt;Projects and Solutions&lt;/kbd&gt; &gt; &lt;kbd&gt;Web Package Management&lt;/kbd&gt; &gt; &lt;kbd&gt;Package Restore&lt;/kbd&gt;

We have not yet found this setting in Project Properties.

Just found it!!!
If it helps anyone in the future

During development, it is very useful to have Chrome autofill my usernames/passwords in localhost. However, due to the new password check feature, it now complains about passwords such as `admin`. How to disable Chrome password check only for localhost?

I found solutions to disable the password checks for all sites. I also found a flag to [disable SSL checks for localhost](https://superuser.com/questions/772762/how-can-i-disable-security-checks-for-localhost) (but not for password check).  
   

Can I disable Chrome password check only for localhost?

i have read the new c++20 feature `no_unique_address` several times and i hope if some one can explain and illustrate with an example better than this example below taken from c++ reference. 

&gt; Explanation Applies to the name being declared in the declaration of a
&gt; non-static data member that&#39;s not a bit field.
&gt; 
&gt; Indicates that this data member need not have an address distinct from
&gt; all other non-static data members of its class. This means that if the
&gt; member has an empty type (e.g. stateless Allocator), the compiler may
&gt; optimise it to occupy no space, just like if it were an empty base. If
&gt; the member is not empty, any tail padding in it may be also reused to
&gt; store other data members.

```
#include &lt;iostream&gt;
 
struct Empty {}; // empty class
 
struct X {
    int i;
    Empty e;
};
 
struct Y {
    int i;
    [[no_unique_address]] Empty e;
};
 
struct Z {
    char c;
    [[no_unique_address]] Empty e1, e2;
};
 
struct W {
    char c[2];
    [[no_unique_address]] Empty e1, e2;
};
 
int main()
{
    // e1 and e2 cannot share the same address because they have the
    // same type, even though they are marked with [[no_unique_address]]. 
    // However, either may share address with c.
    static_assert(sizeof(Z) &gt;= 2);
 
    // e1 and e2 cannot have the same address, but one of them can share with
    // c[0] and the other with c[1]
    std::cout &lt;&lt; &quot;sizeof(W) == 2 is &quot; &lt;&lt; (sizeof(W) == 2) &lt;&lt; &#39;\n&#39;;
}
```

 1. can some one explain to me what is the purpose behind this feature and when should i use it?
 2. *e1 and e2 cannot have the same address, but one of them can share with c[0] and the other with c[1]* can some one explain? why do we have such kind of relation ?

 

what is the new feature in c++20 [[no_unique_address]]?

So i just updated to a new Visual studio version and I&#39;m no longer able to push/pull from/to my azure git repo (cloning works fine).

The exact error I get is
&gt; Cannot determine the organization name for this &#39;dev.azure.com&#39; remote
&gt; url. ensure the `credential.usehttppath` configuration value is set,
&gt; or set the organization name as the user in the remote url
&gt; &#39;{org}@dev.azure.com&#39;.

and only the pull command shows me this error, all the others are failing with git fatal error. I messed with my Credentials Manager cos i suspected it might be the one causing the problem but no luck..

I have a simple class like this.

    public class Greeting
    {
        public string From { get; set; }
        public string To { get; set; } 
        public string Message { get; set; }
    }

Strangely I get the following warning. 

    Severity	Code	Description	Project	File	Line	Suppression State
    Warning	CS8618	Non-nullable property &#39;From&#39; must contain a non-null value when exiting constructor.

    D:\work\MxWork\Elsa2.0WfLearning\MxWork.Elsa2.0Wf.Tuts\src 
    \MxWork.Elsa2Wf.Tuts.BasicActivities\Messages\Greeting.cs	5	Active

I am baffled. These new kind of messages that it throws pulls down my confidence. 
I got them from all the three properties.
And this has suddenly appeared.

Can some one please suggest how this can be mitigated.

## Update

These days I have seen using **default!** like so, and its working.

    public class Greeting
    {
        public string From { get; set; } = default!;
        public string To { get; set; } = default!;
        public string Message { get; set; } = default!;
    }

Also you may put a question mark symbol(?) to indicate that the type is nullable, if you feel appropriate as follows.

```cs
public class Greeting
{
    public string? From { get; set; };
    public string? To { get; set; };
    public string? Message { get; set; };
}
```

I noticed that the default launch configuration generated by VSCode for npm debugging (Launch via NPM) sets the configuration type as &quot;pwa-node&quot; by default.

Does anyone know the meaning of &quot;pwa-node&quot; and why &quot;pwa-node&quot; and not &quot;node&quot;?

The &#39;CascadePackage&#39; package did not load correctly

I have Visual Studio 2022, newest version 17.1.0 running on Windows 10 Pro (up to date). This just started happening yesterday, so maybe it has something to do with the new update.

I open a solution, everything is fine. If I minimize Visual Studio, I can&#39;t get it back.

It&#39;s running. I can see the toolbar icon looks like it&#39;s supposed to when an app is running and I can see it in Task Manager. But I can&#39;t get it back on the screen (I have a single monitor setup). It makes the error sound, and does nothing. I can right-click and open another instance, or I can right-click and select &quot;close window&quot;, but I can&#39;t interact with the original instance at all. If I try to ALT-TAB to it, I can see it, but then it still just makes an error sound and won&#39;t come back up. If I hover over the taskbar button, it will show me the window and I can right-click on that and choose &quot;restore&quot; or &quot;maximize&quot;, and that&#39;s the only way I can get it back.

It seems to do this for multiple solutions, but it&#39;s fairly consistent, once it&#39;s minimized I can&#39;t get it back without closing and reopening the solution or the right-click thing. Anyone run into something like this?
