By default the GAC folder in Windows is located at %windir%\assembly, you can find all the registered DLLs in that folder. Whilst you can open it in windows explorer and view it like any other folder, it is a somewhat special and allows you to have different versions of the same DLL registered in the GAC.
Open up DOS prompt and navigate to the GAC folder, for instance:
and you can see that the GAC is actually a folder inside the assembly folder, and drilling a little deeper reveals that each DLL has its own folder which contains all the registered versions, each as a folder that contains the actual DLL inside:
For .Net 4, the GAC location is now %windir%\Microsoft.Net\assembly.
Global Assembly Cache Tool
You can use gacutil.exe from the command line to view (e.g. gacutil /l), add (e.g. gacutil /i SomeAssembly.dll) or remove (e.g. gacutil /u SomeAssembly) the contents of the GAC, this of course, supports multiple versions of the same assembly too.
I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Check out my new course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. Including basic concepts, HTTP and event triggers, activities, callbacks, nested workflows, design patterns and best practices.
Here is a complete list of all my posts on serverless and AWS Lambda. In the meantime, here are a few of my most popular blog posts.
- Lambda optimization tip – enable HTTP keep-alive
- You are thinking about serverless costs all wrong
- Many faced threats to Serverless security
- We can do better than percentile latencies
- I’m afraid you’re thinking about AWS Lambda cold starts all wrong
- Yubl’s road to Serverless
- AWS Lambda – should you have few monolithic functions or many single-purposed functions?
- AWS Lambda – compare coldstart time with different languages, memory and code sizes
- Guys, we’re doing pagination wrong
