 Both `--exclude` and `--include` options can be used together but `--exclude` takes precedence. You can specify the `--exclude` and `--include` options multiple times to allow for multiple filter expressions.
 
+Note for Powershell / VSTS users
+To exclude or include multiple assemblies when using Powershell scripts or creating a .yaml file for a VSTS build ```%2c``` should be used as a separator. Msbuild will translate this symbol to ```,```. 
+
+```/p:Exclude="[*]*Examples?%2c[*]*Startup"```
+
+VSTS builds do not require double quotes to be unescaped:
+```
+dotnet test --configuration $(buildConfiguration) --no-build /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=$(Build.SourcesDirectory)/TestResults/Coverage/ /p:Exclude="[MyAppName.DebugHost]*%2c[MyAppNamet.WebHost]*%2c[MyAppName.App]*"
+```
+
 ### MSBuild
 
 In this mode, Coverlet doesn't require any additional setup other than including the NuGet package in the unit test project. It integrates with the `dotnet test` infrastructure built into the .NET Core CLI and when enabled, will automatically generate coverage results after tests are run.
