Execute a local file with custom entry point:

dotnet-exec 'HttpPathJsonSample.cs' --entry MainTest

Execute remote file:

dotnet-exec https://github.com/WeihanLi/SamplesInPractice/blob/master/net7Sample/Net7Sample/ArgumentExceptionSample.cs

Execute raw code:

Execute the raw script:

dotnet-exec '1 + 1'

dotnet-exec 'Guid.NewGuid()'

References

Execute raw code with custom references:

NuGet package reference:

dotnet-exec 'CsvHelper.GetCsvText(new[]{1,2,3}).Dump();' -r "nuget: WeihanLi.Npoi,3.0.0" -u "WeihanLi.Npoi"

Local dll reference:

dotnet-exec 'CsvHelper.GetCsvText(new[]{1,2,3}).Dump();' -r "./out/WeihanLi.Npoi.dll" -u "WeihanLi.Npoi"

Local dll in a folder references:

dotnet-exec 'CsvHelper.GetCsvText(new[]{1,2,3}).Dump();' -r "folder: ./out" -u "WeihanLi.Npoi"

Local project reference:

dotnet-exec 'CsvHelper.GetCsvText(new[]{1,2,3}).Dump();' -r "project: ./WeihanLi.Npoi.csproj" -u "WeihanLi.Npoi"

Framework reference:

dotnet-exec 'WebApplication.Create().Run();' --reference 'framework:web'

Web framework reference in one option:

dotnet-exec 'WebApplication.Create().Run();' --web

Usings

Execute raw code with custom usings:

dotnet-exec 'WriteLine(1+1);' --using "static System.Console"

dotnet-exec 'CsvHelper.GetCsvText(new[]{1,2,3}).Dump()' -r "nuget:WeihanLi.Npoi,3.0.0" -u WeihanLi.Npoi

More

Execute with additional dependencies

dotnet-exec 'typeof(LocalType).FullName.Dump();' --ad FileLocalType2.cs

dotnet-exec 'typeof(LocalType).FullName.Dump();' --addition FileLocalType2.cs

or

dotnet-exec 'typeof(LocalType).FullName.Dump();' FileLocalType2.cs

Execute with exacting references and usings from the project file

dotnet-exec 'typeof(LocalType).FullName.Dump();' --project ./Sample.csproj

Execute file with preview features:

Config Profile

You can customize the config you used often into a config profile to reuse it for convenience.

List the profiles had configured:

dotnet-exec profile ls

Configure a profile:

dotnet-exec profile set web -r "nuget:WeihanLi.Web.Extensions" -u 'WeihanLi.Web.Extensions' --web --wide false

Get the profile details:

dotnet-exec profile get web

Remove the profile not needed:

dotnet-exec profile rm web

Executing with specific profile config:

dotnet-exec 'WebApplication.Create().Chain(_=>_.MapRuntimeInfo()).Run();' --profile web --using 'WeihanLi.Extensions'

Executing with specific profile config and remove preset specific using:

dotnet-exec 'WebApplication.Create().Run();' --profile web --using '-WeihanLi.Extensions'

Alias command

The alias command allows you to manage aliases for frequently used commands.

List aliases

To list all configured aliases, use the list subcommand:

dotnet-exec alias list

You can also use dotnet-exec alias ls to list aliases.

Set alias

To set a new alias, use the set subcommand followed by the alias name and value:

dotnet-exec alias set <aliasName> <aliasValue>

For example, to set an alias for generating a new GUID:

dotnet-exec alias set guid "Guid.NewGuid()"
