+# Updating coverage tool zips procedure
+
+FCC uses 3 coverage providers, these are zip files included in the VSIX.
+These get extracted to AppData\Local\FineCodeCoverage
+
+You need to debug FCC to ensure updates to these zips work. This will override the existing.
+
+## All updated zips will need to follow this procedure.
+
+1. Add to \FineCodeCoverage\Shared Files\ZippedTools directory
+2. Add as a linked file to the FineCodeCoverage and FineCodeCoverage2022 projects
+
+Expand the project in solution explorer  
+Right click on the ZippedTools directory  
+Add -> Existing Item  
+Navigate to \FineCodeCoverage\Shared Files\ZippedTools  
+In the browser dialog select All files to see the zips  
+Select the zip you want to add  
+Click the drop down arrow on the Add button and select Add as Link
+
+3. Set the Build properties in the properties window
+
+Select the file  
+Set Build Action to Content  
+Set Include in VSIX to True
+
+4. Remove the previous zip in solution explorer
+
+5. For all updated zips debug an appropriate project ( details follow ) and if coverage is provided the old zip can be deleted from \FineCodeCoverage\Shared Files\ZippedTools
+
+## How to update the zips
+
+### msCodeCoverage
+
+1. [Download the nuget package](https://www.nuget.org/packages/Microsoft.CodeCoverage/).
+2. Change the file extension to zip
+3. Check to see if the zip is compatible
+
+The name should be of the form microsoft.codecoverage.VERSION.zip
+It needs to be compatible with MsCodeCoverageRunSettingsService
+
+```csharp
+public void Initialize(string appDataFolder, IFCCEngine fccEngine, CancellationToken cancellationToken)
+{
+    this.fccEngine = fccEngine;
+    var zipDestination = toolUnzipper.EnsureUnzipped(appDataFolder, zipDirectoryName,zipPrefix, cancellationToken);
+    fccMsTestAdapterPath = Path.Combine(zipDestination, "build", "netstandard2.0");
+    shimPath = Path.Combine(zipDestination, "build", "netstandard2.0", "CodeCoverage", "coreclr", "Microsoft.VisualStudio.CodeCoverage.Shim.dll");
+}
+```
+
+The fccMsTestAdapterPath needs to be a directory that contains a ...collector.dll which is currently called Microsoft.VisualStudio.TraceDataCollector.dll.  
+The shimPath needs to exist.
+
+4. Add the zip to the solution - see instruction at the top of this page.
+5. Debug
+
+Debug a project with the option MsCodeCoverage Yes
+
+### coverletCollector
+
+1. [Download the nuget package](https://www.nuget.org/packages/coverlet.collector/).
+2. Change the file extension to zip
+3. Check to see if the zip is compatible
+   The name should be of the form coverlet.collector.VERSION.zip
+   It needs to be compatible with CoverletDataCollectorUtil
+
+```csharp
+public void Initialize(string appDataFolder,CancellationToken cancellationToken)
+{
+    var zipDestination = toolUnzipper.EnsureUnzipped(appDataFolder, zipDirectoryName, zipPrefix, cancellationToken);
+    var testAdapterPath = Path.Combine(zipDestination, "build", "netstandard2.0");
+    TestAdapterPathArg = $@"""{testAdapterPath}""";
+}
+```
+
+Given that it is a data collector like msCodeCoverage the testAdapterPath needs to be a directory that contains a ...collector.dll which is currently called coverlet.collector.dll. 4. Add the zip to the solution - see instruction at the top of this page. 5. Debug
+
+Debug an SDK style project with RunMsCodeCoverage No and with the test project having an MSBuild property `<UseDataCollector/>`
+
+### coverlet
+
+1. dotnet tool install --global coverlet.console
+
+This will create or update installation in username/.dotnet/tools directory
+
+2. Create a directory - coverlet.console.VERSION
+3. Create a sub directory - .store
+
+Copy the following from within username/.dotnet/tools
+coverlet.exe into coverlet.console.VERSION
+coverlet.console dirctory into .store.
+
+4. Add the zip to the solution - see instruction at the top of this page.
+5. Debug
+
+Debug an SDK style project with RunMsCodeCoverage No and with the test project **not** having an MSBuild property `<UseDataCollector/>`
