General Stuff

Clear all \bin \obj

Be careful were you run this, you could kill your OS install if you ran it somewhere like system32.

Get-ChildItem .\ -include bin,obj -Recurse | foreach ($_) { remove-item $_.fullname -Force -Recurse }

Extract the contents of an *.msi file.

msiexec /a SSCERuntime-ENU-x64.msi

.NET 5 Stuff

dotnet help

.NET

Bitmap bitmap = (Bitmap)Image.FromFile(@"mypath.bmp");

Nuget

# Clear the 3.x+ cache (use either command)
dotnet nuget locals http-cache --clear
nuget locals http-cache -clear

# Clear the 2.x cache (NuGet CLI 3.5 and earlier only)
nuget locals packages-cache -clear

# Clear the global packages folder (use either command)
dotnet nuget locals global-packages --clear
nuget locals global-packages -clear

# Clear the temporary cache (use either command)
dotnet nuget locals temp --clear
nuget locals temp -clear

# Clear the plugins cache (use either command)
dotnet nuget locals plugins-cache --clear
nuget locals plugins-cache -clear

# Clear all caches (use either command)
dotnet nuget locals all --clear
nuget locals all -clear

After running any of these commands nuget could (read most likely will) throw a wobbly and complain about missing packages. If this does occur you can use the following command and options to get back to a working solution.

Firstly, do a safe reinstall of packages. The reinstall command is actually quite destructive in some instances without the -safe flag it will reinstall, but it will reinstall the very latest version of any package which could also introduce compatibility issues. So, run this:

Update-Package -Reinstall -Safe

If this is still an issue you can try executing “Clean Solution” then run the “Rebuild” option. If this still produces issues. Go to Tools -> Options -> Nuget Package Manager -> Clear All Nuget Cache(s). Restart VS (just to be safe) and then run another clean and rebuild.

This *should* fix things. If it doesn’t, it’s off the StackOverflow for you … sorry 🙂
