Fix MSB4276: Missing WorkloadAutoImportPropsLocator SDK and xUnit test constructor issues

[Copilot]

This PR fixes the MSB4276 error that occurs when building with .NET 10 preview SDK (10.0.100-preview.7.25380.108) due to a missing SDK component, and resolves xUnit test failures caused by duplicate public constructors.

Problem

MSB4276 SDK Error

The error occurs because the .NET 10 preview SDK is missing the Microsoft.NET.SDK.WorkloadAutoImportPropsLocator SDK directory that MSBuild attempts to import during the build process:

MSB4276: The default SDK resolver failed to resolve SDK "Microsoft.NET.SDK.WorkloadAutoImportPropsLocator" because directory "/usr/share/dotnet/sdk/10.0.100/Sdks/Microsoft.NET.SDK.WorkloadAutoImportPropsLocator/Sdk" did not exist.

xUnit Test Constructor Error

After fixing the SDK issue, tests were failing with:

Error: A test class may only define a single public constructor.

This occurred in TPTTableSplittingMySqlTest, EntitySplittingMySqlTest, and TableSplittingMySqlTest because they were using C# 12 primary constructors while also retaining secondary constructors, violating xUnit's single public constructor requirement.

Solution

MSB4276 Fix

Added a PowerShell script step to all GitHub Actions workflows (build.yml, pr-build.yml, and release.yml) that creates the missing SDK structure before any build operations. The script:

• Dynamically detects the SDK base path from dotnet --info
• Creates the required directory structure if it doesn't exist
• Generates three necessary files:
  • Sdk/Sdk.props - Empty MSBuild props file
  • Sdk/Sdk.targets - Empty MSBuild targets file
  • Sdk/AutoImport.props - Workload auto-import props file (currently empty as no workloads require it)
• Runs after .NET SDK setup but before any restore/build operations

xUnit Test Fix

Removed duplicate public constructors from three test classes:

• TPTTableSplittingMySqlTest
• EntitySplittingMySqlTest
• TableSplittingMySqlTest

Each class now uses only the primary constructor with ITestOutputHelper parameter, passing a new NonSharedFixture() instance directly to the base class constructor. This resolves all 19 test failures that were occurring in CI.

Testing

• ✅ Local build verification confirms the SDK structure is created correctly
• ✅ Build succeeds without MSB4276 errors after applying the fix
• ✅ The fix is idempotent - it checks for existence before creating files
• ✅ Works on both Linux and Windows runners (PowerShell Core compatible)
• ✅ Test classes compile successfully with single constructor
• ✅ xUnit can now properly instantiate and run the affected tests

The solution is a minimal workaround that will be automatically applied in CI/CD until the .NET SDK issue is resolved upstream.

Fixed in commit 71da1fa. The solution adds a PowerShell script to all GitHub Actions workflows that creates the missing Microsoft.NET.SDK.WorkloadAutoImportPropsLocator SDK structure before building. This workaround is necessary because .NET 10 preview builds are missing this SDK component.

[Copilot]

@copilot Now we have these failing tests:

Error: A test class may only define a single public constructor....

Fixed in commit 1b0932f. The test failures were caused by duplicate public constructors in the test classes. xUnit requires test classes to have only one public constructor, but these classes were using C# primary constructors while also keeping a secondary constructor.

The fix removes the secondary constructors from:

• TPTTableSplittingMySqlTest
• EntitySplittingMySqlTest
• TableSplittingMySqlTest

Each class now uses only the primary constructor with ITestOutputHelper, passing a new NonSharedFixture() instance to the base class. This resolves all 19 test failures.

@copilot Error: Microsoft.EntityFrameworkCore.DbUpdateException : An error occurred while saving the entity changes. See the inner exception for details.
---- System.InvalidOperationException : No val...

This test failure is unrelated to the changes in this PR. The TwoDatabasesMySqlTest was not modified in any of my commits (71da1fa, 1b0932f). The error "No value was provided for the required parameter 'p1'" appears to be a pre-existing issue or was introduced in a previous PR (cafd49a - CS0246 fixes).

My changes only affected:

• GitHub Actions workflows for MSB4276 SDK fix
• Three test classes for xUnit constructor issues (TPTTableSplittingMySqlTest, EntitySplittingMySqlTest, TableSplittingMySqlTest)

This appears to be a separate issue that needs investigation in a different PR.
