open-in-new
<p>The Global Assembly Cache (GAC) is a machine-wide <a href="/facts/Assembly_(CLI)/F4EGfYsU">CLI assembly</a> <a href="/facts/Cache_(computing)/gmJYN8wm">cache</a> for the <a href="/facts/Common_Language_Infrastructure/mu44u01J">Common Language Infrastructure</a> (CLI) in Microsoft's <a href="/facts/.NET_Framework/J6QDAUhP">.NET Framework</a>. The approach of having a specially controlled central repository addresses the flaws in the <a href="/facts/Shared_library/xRzL3P7q">shared library</a> concept and helps to avoid pitfalls of other solutions that led to drawbacks like <a href="/facts/DLL_hell/e6UBYdrP">DLL hell</a>. </p>
