SDK Command Prompt
The SDK Command Prompt is new in the .NET Framework 2.0, and automatically sets the SDK environment variables that allow you to easily use the .NET Framework tools.
The required environment variable values are provided by the sdkvars.bat batch file located in the SDK\v2.0\bin folder. The SDK Command Prompt calls this batch file, but the variables expire when you close the command prompt.
To make the settings permanent, you can add the variable values to your system variables by using the Environment Variables dialog box, which you can access from the Advanced tab of System Properties.
To start the SDK Command Prompt
Click Start, point to All Programs, point to Microsoft .NET Framework SDK v2.0, and then click SDK Command Prompt.
