Issue: I am trying to run a command PM> add-migration testing.

Detail: I know why I am getting this error. Due to security reasons, our company doesn't allow us to run any files inside C:\Users\name\... . so init.ps1 is getting blocked since i cant run inside that folder.

To fix, I moved my Visual Studio project code folder to the following path: C:\adminrun\repos. Here I admin access and I am allow to run any files. This lets me run project but init.ps1 is still inside C:\Users\name\.nuget\packages (this path is blocked)

Question: can I run add-migration command without PM?

Error:

& : File C:\Users\name.nuget\packages\microsoft.entityframeworkcore.tools\6.0.13\tools\init.ps1 cannot be loaded because its operation is blocked by software restriction policies, such as those created by using Group Policy.

Step 1, change the downloaded NuGet package storage location:

1. According to the following file path, find a file named "NuGet.Config", or search for the file directly.

   C:\Users{system username}\AppData\Roaming\NuGet

2. Open the "NuGet.Config" file, we can see the original file content as follows:

   xml version="1.0" encoding="utf-8"?
    <configuration>
    <packageSources>
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    packageSources>
   configuration>  
   

3. Replace its contents with the following and save:

   xml version="1.0" encoding="utf-8"?  
   <configuration>
    <packageSources>
        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    packageSources>
   
   
    <config>
   
        <add key="globalPackagesFolder" value=" The new path where you want the NuGet package to be stored " />
   
   
        <add key="repositoryPath" value=" The new path where you want the NuGet package to be stored " />
    config>
   configuration>
   

Step2, modify the VS offline package reference address:

1. According to the following file path, find a file named "Microsoft.VisualStudio.Offline.config", or search for the file directly.

   C:\Program Files (x86)\NuGet\Config

2. Open the "Microsoft.VisualStudio.Offline.config" file, we can see the original file content as follows:

   xml version="1.0" encoding="utf-8"?
    <configuration>
    <packageSources>
    <add key="Microsoft Visual Studio Offline Packages" value="C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\"/>
   packageSources>
   configuration>
   

3. Replace its contents with the following and save:

   xml version="1.0" encoding="utf-8"?
    <configuration>
    <packageSources>
    <add key="Microsoft Visual Studio Offline Packages" value=" The new path where you want the NuGet package to be stored "/>
   packageSources>
   
   
    <config>
    <add key="globalPackagesFolder" value=" The new path where you want the NuGet package to be stored " />
    config>
    configuration>
   

Step3, verify that the modified new path is successful:

Re-open a project with VS, uninstall a reference package in the project and reinstall it, find the reference item in the project reference list, right-click to open the property panel, in the "Path" column, we can clearly find the referenced The address has become the new address we just set.
