Answer 1

Try any of the following ...

1. Enable Just My Code
   Go to Tools > Options > Debugging > General
   Check "Enable Just my Code"
   
   
   

2. Cache Symbols Locally
   Go to Tools > Options > Debugging > Symbols Browse to local directory (make sure it's not on a network share) Click "Load All Symbols" or run the project to hydrate the cache

   
   
   

3. Remove Remote Symbol Servers

   When you select a remote symbol server, Visual Studio gives you the following warning:

   The performance of remote symbols stores can vary due to latency, bandwidth, or availability of servers. Debugging performance can be improved by selecting the option to load only specified modules when enabling this server

   After loading your symbol cache, deselect remote symbols servers

   Go to Tools > Options > Debugging > Symbols Deselect "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.
