Visual studio 2019 - package manager GUI freezes when using local Nuget repository but when fiddler is working it works fast

Question

I am using local Nuget repository on air gap environment.

When I use the Nuget package manager of Visual Studio 2019 and I search for package or even when moving from Browse to Installed and vice versa the application freezes for at least half a minute.

When I tried to investigate the issue with Fiddler I have found out that as long as Fiddler is up The problem is solved.

How come it works fine when fiddler is on?

Answer 1

Quite strange and not sure whether fiddler finally caused the problem or some suitable factor.

Please try the following steps to check your VS environment:

1) disable any third party extensions under Extensions --> Manage Extensions --> Installed .

2) close VS, delete all files under C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\16.0_xxx\ComponentModelCache , and then restart VS to test again.

3) type [Net.ServicePointManager]::SecurityProtocol=[Net.ServicePointManager]::SecurityProtocol-bOR [Net.SecurityProtocolType]::Tls12 under Tools --> Nuget Package Manager --> Package Manager Console

4) close vs, delete global nuget.config file under C:\Users\xxx\AppData\Roaming\NuGet , restart to test again.

5) reset vs settings under Tools --> Import and Export Settings --> Reset vs settings

6) type devenv /safemode under Developer Command prompt for VS to start a new pure VS to test again.

7) repair vs or update it if there is a new release version.

Besides , as your choice, you could initialize your VS. Close VS, just delete the whole C:\Users\xxx\AppData\Local\Microsoft\VisualStudio\16.0_xxx folder.
