Build Conflict between System.Net.Http-Package & Framework-Default Assembly #1258
Description
Context
Net-Framework (4.8.1)
Wiremock uses a PackageReference to Nuget Package "System.Net.Http" in Version 4.3.4
System.Net.Http-Package
NugetPackage Version: 4.3.4 (Current and newest)
Actual Assembly version sinde: 4.1.1.3
System.Net.Http Assembly included in GAC in Net-Framework 4.8
Assembly Version: 4.2.0.0
Describe the bug
Setup:
- Main Project with implicit GAC/System-Assembly usage (=4.2.0.0)
- Unit Test Project with WireMock which adds implicit reference to Package 4.3.4 (=4.1.1.3 as actual assembly Version)
- A Unit Tests exists wich uses and exchanges a type from System.Net.Http with the tested Main Project
Result:
- Build of Test-project fails because of conflict (CSC: Error CS1705)
- Implicitly referenced System.Net.Http in Test-Project can't be explicitly upgraded because no NugetPackage-Version exists with a version as high as the Framework-provided version
Expected behavior:
- Should be possible to build without downgrading the System.Net.Http-Assembly version in den Main Project
- Is a reference to System.Net.Http-Package necessary when a newer Framework provided Assembly exists in GAC for 4.8?
Other related info
Things that did not work as a workaround:
- Assembly Redirect/Rebinding
- Not exposing internal References with PrivateAssets
- Trying to explicitly add the System-Assembly in Test Project
- Trying to skip the implicit inclusion of the Package in Test-Project
