after trying several times the error might be shorter like this

Reproduction Steps

• cdk init app --language csharp
• dotnet build src
• cdk synth or cdk list

Possible Solution

No response

Additional Information/Context

My home folder is C:\Users\Vitalii Ivanov, I suspect the space in my username causes the issue, but only for dotnet project.

CDK CLI Version

2.149.0 (build c8e5924)

Framework Version

No response

Node.js Version

20.15.1

OS

windows 11 - 22H2 (22621.3880)

Language

.NET

Language Version

.net 6

Other information

I wasn't able to reproduce the issue for the typescript project on the same machine.

cdk init generates .net 6 project, upgrading to .net 8 doesn't help.

I tried to change the temporary folder location as described here and after that cdk synth produced CF template successfully for the dotnet project.

@ivanovvitaly Good morning. Thanks for opening the issue. Although, I'm unable to reproduce the issue:

• Following Getting started with the AWS CDK
  • Installed Nodejs version v20.15.1 (LTS)
  • Installed TypeScript using command npm -g install typescript (optional for .NET projects)
  • Installed AWS CDK CLI using command npm install -g aws-cdk
  • Configured AWS credentials and bootstrapped my environment.
• Created folder named Vitalii Ivanov from command line.
• Changed current directory to Vitalii Ivanov.
• Executed command cdk init app --language csharp
• Ran command dotnet build src.
• Ran command cdk synth

cdk synth successfully generated the below CloudFormation template without any error:

I changed $env:TMP to D:\cdkrepro\Vitalii Ivanov temporarily and got the below error:

It appears that the default value of $env:TMP is set to <<Drive>>:\Users\<<username>>\AppData\Local\Temp on Windows machine. In your case, it is C:\Users\Vitalii Ivanov\AppData\Local\Temp, which resulted in the error since your username contained space character.

So looks like the other issue #1296 was not reopened after comment by other AWS SDK engineer.

I will transfer this issue to JSII repository.

Thanks,
Ashish
