Chapter 37: Using Visual Studio .NET to Create Web Parts 1013
There are two default locations where the .NET common language runtime will look
for .NET assemblies when operating within the context of a WSS-extended server.
One of them is the Global Assembly Cache, and the other one is the bin directory of
your WSS extended virtual server root directory (for example, the c:\inetpub\wwwroot
\bin folder).
To specify the build output path
During Web Part development, changing the build output path to the BIN folder of
your SharePoint virtual server is recommended so that you don’t have to copy the
assembly file every time after compilation.
1. In the Solution Explorer, right-click your project name, and then click
Properties.
2. Under Configuration Properties\Build\Outputs, set the Output Path to
the Bin folder within the root folder of the Windows SharePoint Services
extended virtual server, for example: c:\inetpub\wwwroot\bin.
Deploying a Web Part
Now you are ready to compile the Web Part. However, before you’re able to use the
Web Part, there are a couple of steps left that you need to take. The
section of the Web.config file specifies which Web Parts are trusted. So, you need to
register your own Web Part as a safe control. The following code shows an example
of the section:
..
The Assembly attribute of the element shows the assembly name of
the Web Part assembly, and optionally a version number, a culture reference, and a
public key token. Now you should determine the public key token of your Web Part
library assembly so that you can create a safe control entry for your Web Part in the
Web.config file. The easiest way to accomplish this is to copy the assembly DLL file
into the Global Assembly Cache. Locate the DLL file, right-click the DLL, and copy
the public key token. After this, don’t forget to remove the assembly .DLL file from the
Global Assembly Cache. You could also use the Strong Name tool (SN.exe) to obtain
the public key token.
1. From a command prompt on the drive where you installed Visual Studio .NET,
type the following: cd \Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Bin\
or \Program Files\Microsoft Visual Studio.NET 2003\SDK\v1.1\Bin if you are using
Visual Studio.NET 2003.
