If you want the Angular Development Server ng to serve at the external IP of your computer to allow external clients to access the app, use following command.
ng serve --host=0.0.0.0 --disable-host-check
If you want PowerShell to wait for an action to complete, you can display a loading spinner using these few lines of code.
The script will print a new dot every three seconds until the condition in the until-clause is fulfilled.
The result looks like this:

MS LocalDB has the possibility to share your personal LocalDB instance with other users on the computer.
You can use the CLI tool SqlLocalDb.exe to share the instance. It is available in the Developer Command Prompt of Visual Studio.
This is the documentation of the share action:
share|h ["owner SID or account"] "private name" "shared name" Shares the specified private instance using the specified shared name. If the user SID or account name is omitted, it defaults to current user.
Usage:
C:\Windows\System32>sqllocaldb share contosolab\doering MSSQLLocalDB ShareLocalDb Private LocalDB instance "MSSQLLocalDB" (owner: CONTOSOLAB\doering) shared with the shared name: "ShareLocalDb".
Important: the argument “owner SID or account” must be your own user not the user you want to share the instance with.
The instance then appears as .\ShareLocalDb in the list.
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional>sqllocaldb info .\ShareLocalDb MSSQLLocalDB
You can use the shared instance in connection strings like this:
Data Source=(LocalDb)\.\ShareLocalDb;database=MyDatabase;trusted_connection=yes;
There’s no command line tool on Windows like Grep on Linux to search for a specific text in all files recursively. But there’s a simple alternative.
Bash
grep -r "peter" *
PowerShell
ls * -r | sls "peter"
Did you know the Lazy class in the System namespace?
This little useful helper was introduced with .NET 4. You can use it to lazy initialize properties.
The ResolvePackagePath()-method gets called if the value is needed the first time.
The property IsValueCreated lets you check if the value is already initialized.
Many companies use a http proxy with authentication. Since TFS 2017 the agents are based on .NET Core to be cross-platform. The new agents are unable to obtain the proxy settings from the operating system (Internet Explorer settings).
I’ve found this solution to set a http proxy for the VSTS agents.
- Create a file .proxy in the agents root folder and write the proxy in it.
Example: http://proxy.contoso.org:8080
- Username and password can be set with environment variables
[Environment]::SetEnvironmentVariable("VSTS_HTTP_PROXY_USERNAME", "proxyuser", "User") [Environment]::SetEnvironmentVariable("VSTS_HTTP_PROXY_PASSWORD", "proxypassword", "User")See also the documentation on GitHub.
In the app.config/web.config you can use the configuration section <system.net> <mailSettings> <smtp> to configure how to deliver e-mails which are sent using the MailMessage and SmtpClient classes in your program.
In development environment you usually don’t want the e-mails to be delivered. Today I’ve found a awesome configuration option, which enables that all outgoing e-mails go to an local folder or file share as eml files.
Did you already know the methods Path.GetTempPath() and Path.GetTempFileName() in the System.IO namespace.
The very useful method GetTempFileName() creates a temporary file for you in a location you have write access. You then can write temporary data to this file.
SharePoint generates for each request a random GUID which correlates all log messages in the ULS log which are printed during the current request. The Correlation ID is also printed to error pages. If you want more information about an error page you can use the Correlation ID to find the right log messages in the ULS log.
Recently I wanted to get the current request’s Correlation ID to share it with an external webservice to have the same correlation ID in all depending systems.
You can add following code to your ASP page to get the Correlation ID.
