This repository contains assets that are binary files or too large to be checked in directly. Packages are uploaded to the default transport channel's feed.
- Submit a PR with the new assets.
- After the PR is merged, an internal build publishes assets to the Build Assets Registry and an auto PR will be opened in the subscribing repositories.
- Optional step: Local testing.
Let's assume we are adding a new unit test for the GZip feature from the System.IO.Compression namespace, and the test depends on a file called example.gz.
After the PR is merged an internal build will publish the packages to a public feed and update the Build Assets Registry. Subscribers to this repository will receive an auto PR update with the updated package version.
Testing your assets in your local machine is an optional step you can perform before submitting your PR. Local testing is usually not necessary due to the nature of this repository, which mostly only deals with static files. Feel free to skip this section.
a) Save example.gz inside runtime-assets\src\System.IO.Compression.TestData\GZipTestData.
b) Run build.cmd --pack from the runtime-assets\ root folder.
c) Verify that your package was generated with the new test data.
I. Go to runtime-assets\artifacts\packages\Debug\NonShipping.
II. Temporarily rename System.IO.Compression.TestData.7.0.0-dev.nupkg to the extension *.nupkg.zip.
III. Open it with your preferred Zip app.
IV. Inside the zip, navigate to contentFiles\any\any\GZipTestData and verify that the new example.gz file can be found there.
V. Close the Zip window, and revert the name to *.nupkg.
d) Go to your runtime folder.
e) Edit Nuget.config located in the root folder, and inside the <packageSources> section, add a new key that points to the temporary folder as a source: <add key="tmp" value="D:\runtime-assets\artifacts\packages\Debug\NonShipping" /> (make sure to adjust the root path to your repo folder).
f) Go to runtime\src\libraries\System.IO.Compression\tests and run dotnet build or dotnet restore. This will force consuming the new nupkg and will place it in your local .nuget cache (usually, it's C:\Users\%USERNAME%\.nuget).
g) At the time of writing this guide, the .NET version tracked in the main branch of the runtime repo was 7.0. So for this example, assume the version number is 7.0.0. Navigate to your local .nuget folder, go to .nuget\System.IO.Compression.TestData and verify that the folder 7.0.0-dev is there, and that 7.0.0-dev\contentFiles\any\any\GZipTestData\example.gz is there.
h) Run your new unit test that depends on that file, it should be able to find the file.
i) If you need to update the package with additional files, make sure to delete the folder .nuget\System.IO.Compression.TestData\7.0.0-dev\, then repeat steps b through h.
