Deplying a class library to GAC in the Visual Studio

To deploy a class library to the GAC in Visual Studio, perform the following:

1.Open the project Properties and go to Build events.

2.Set the Pre-build event command line to:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\x64\gacutil.exe" /u $(TargetName)

3.Set the Post-build event command line to:

"C:\Program Files (x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools\x64\gacutil.exe" /i $(TargetPath)

When you compile a new version, before building the project, the existing Web Part will be removed from GAC. Then, once the build is successful, the new Web Part will be installed.

The following command is used to search an assembly in the GAC.

gacutil /l | findstr aseembly-name

For example,

gacutil /l | findstr Oracle.DataAccess
