tslint: Assets parent identified as different Construct type

[costleya]

const buildInstructions = new FileAsset(this, 'DotnetDevexPipelineBuildInstructions', {
    path: './content/build.sh'
});

yields

Type 'DotnetDevexPipelineStack' is not assignable to type 'Construct'.
    Types of property 'parent' are incompatible.
      Type 'import("/Users/costleya/Work/dotnet-devex-pipeline/node_modules/@aws-cdk/cdk/lib/core/construct").Construct | undefined' is not assignable to type 'import("/Users/costleya/Work/dotnet-devex-pipeline/node_modules/@aws-cdk/assets/node_modules/@aws-cdk/cdk/lib/core/construct").Construct | undefined'.
        Type 'import("/Users/costleya/Work/dotnet-devex-pipeline/node_modules/@aws-cdk/cdk/lib/core/construct").Construct' is not assignable to type 'import("/Users/costleya/Work/dotnet-devex-pipeline/node_modules/@aws-cdk/assets/node_modules/@aws-cdk/cdk/lib/core/construct").Construct'.
          Types have separate declarations of a private property '_children'.

This is supposed to be fixed in >0.15.2 as we introduced peer dependencies (#1091, #979). The problem is not specific to assets, it's because you have two versions of @aws-cdk/cdk in your closure and TypeScript won't allow you to interchangeably use them.

Closing for now, let us know if this persists with the latest version

To elaborate on this error in case someone reached this page later like I did. While you're developing in typescript and adding new services you may run into an issue where all of your aws-cdk/aws-{someservice} is running on 1.6.0. But the new package you installed will be version 1.6.1 and will give you an error every time you're using "this." Easy fix with npm upgrade command
